1.  Introduction

1.1.  Network Printing Environment

  The management of producing a printed document, in any computer
  environment, is a complex subject. Basically, the task can be divided
  into two overlapping pieces, the management of printing and the
  management of the printer. Printing encompasses the entire process of
  producing a printed document from generation of the file to be
  printed, selection of a printer, choosing printing properties,
  routing, queuing, resource management, scheduling, and final printing
  including notifying the user.  Most of the printing process is outside
  the scope of the model presented here; only the management of the
  printer is covered.

1.2.  Printer Device Overview

  A printer is the physical device that takes media from an input
  source, produces marks on that media according to some page
  description or page control language and puts the result in some
  output destination, possibly with finishing applied. Printers are
  complex devices that consume supplies, produce waste and have
  mechanical problems. In the management of the physical printing
  device the description, status and alert information concerning the
  printer and its various subparts has to be made available to the



Smith, Wright, Hastings, Zilles & Gyllenskog                    [Page 4]

RFC 1759                      Printer MIB                     March 1995


  management application so that it can be reported to the end user,
  key operators for the replenishment of supplies or the repair or
  maintenance of the device. The information needed in the management
  of the physical printer and the management of a printing job overlap
  highly and many of the tasks in each management area require the same
  or similar information.

1.3.  Categories of Printer Information

  Information about printers is classified into three basic categories,
  descriptions, status and alerts.

1.3.1.  Descriptions

  Descriptions convey information about the configuration and
  capabilities of the printer and its various sub-units. This
  information is largely static information and does not generally
  change during the operation of the system but may change as the
  printer is repaired, reconfigured or upgraded. The descriptions are
  one part of the visible state of the printer where state means the
  condition of being of the printer at any point in time.

1.3.2.  Status

  Status is the information regarding the current operating state of
  the printer and its various sub-units. Status is the rest of the
  visible state of the printer. As an example of the use of status, a
  management application must be able to determine if the various sub-
  units are ready to print or are in some state that prevents printing
  or may prevent printing in the future.

1.3.3.  Alerts

  An Alert is the representation of a reportable event in the printer.
  An event is a change in the state of the printer. Some of those state
  changes are of interest to a management application and are therefore
  reportable. Typically, these are the events that affect the printer's
  ability to print. Alerts usually occur asynchronously to the
  operation of the computer system(s) to which the printer is attached.
  For convenience below, "alert" will be used for both the event caused
  by a change in the printer's state and for the representation of that
  event.

  Alerts can be classified into two basic categories, critical and
  non-critical.  A critical alert is one that is triggered by entry
  into a state in which the printer is stopped and printing can not
  continue until the condition that caused critical alert is
  eliminated. "Out of paper", "toner empty" and "output bin full" are



Smith, Wright, Hastings, Zilles & Gyllenskog                    [Page 5]

RFC 1759                      Printer MIB                     March 1995


  examples of critical alerts. Non-critical alerts are triggered by
  those events that enter a state in which printing is not stopped.
  Such a non-critical state may, at some future time, lead to a state
  in which printing may be stopped.  Examples of this kind of non-
  critical alerts are "input media low", "toner low" and "output bin
  nearly full". Or, a non-critical alert may simply provide
  information, such as signaling a configuration changed in the
  printer.

  Description, status and alert information about printer can be
  thought of as a data base describing the printer. The management
  application for a printer will want to view the printer data base
  differently depending on how and for what purposes the information in
  the data base is needed.

2.  Printer Model

  In order to accomplish the management of the printer, an abstract
  model of the printer is needed to represent the sub-units from which
  the printer is composed. A printer can be described as consisting of
  13 types of sub-units. It is important to note that the sub-units of
  a printer do not necessarily relate directly to any physically
  identifiable mechanism. Sub-units can also be a set of definable
  logical processes, such as interpreters for page description
  languages or command processors that set various operating modes of
  the printer.

Smith, Wright, Hastings, Zilles & Gyllenskog                    [Page 7]

RFC 1759                      Printer MIB                     March 1995


2.1.  Overview of the Printer Model

  The model has three basic parts: (1) the flow of a print file into an
  interpreter and onto the marker, (2) the flow of media through the
  marker and (3) the auxiliary sub-units that control and facilitate
  the two prior flows.  The flow of the print data comes through a
  physical connection on which some form of transport protocol stack is
  running.  The data provided by the transport protocol (interface)
  appears on a channel which is the input to an interpreter. The
  interpreter converts the print data into a form suitable for marking
  on the media.

  The media resides in Input sub-units from which the media is selected
  and then transported via a Media Path first to a Marking sub-unit and
  then onto an Output sub-unit with (optionally) some finishing
  operations being performed.  The auxiliary sub-units facilitate
  control of the printer, inquiry/control of the operator panel,
  reporting of alerts, and the adaptation of the printer to various
  natural languages and characters sets. All the software sub-units run
  on the System Controller which represents the processor, memory and
  storage systems of the Printer.  Each of the sub-units is discussed
  in more detail below.

  All of the sub-units other than the Alerts report only state
  information, either a description or a status. The Alerts sub-unit
  reports event information.

2.2.  Printer Sub-Units

  A printer is composed of 13 types of sub-units, called groups.  The
  following sections describe the different types of sub-units.

2.2.1.  General Printer

  The general printer sub-unit is responsible for the overall control
  and status of the printer. There is exactly one general printer sub-
  unit in a printer. The general printer sub-unit is represented by the
  General Printer Group in the model. In addition to the providing the
  status of the whole printer and allowing the printer to be reset,
  this Group provides information on the status of the packaging of the
  printer, in particular, the covers. The general printer sub-unit is
  usually implemented on the system controller.

  The localization portion of the general printer sub-unit is
  responsible for identifying the natural language, country, and
  character set in which character strings are expressed. There may be
  one or more localizations supported per printer. The available
  localizations are represented by the Localization table.



Smith, Wright, Hastings, Zilles & Gyllenskog                    [Page 8]

RFC 1759                      Printer MIB                     March 1995


  Localization is only performed on those strings in the MIB that are
  explicitely marked as being localized.  All other character strings
  are returned in ASCII.

  The character set portion of the general printer sub-unit is
  responsible for identifying the possible character sets that are used
  by the interpreters, the operator console, and in network management
  requests for display objects. There may be one or more character sets
  per printer.  The understood character sets are represented by the
  Character Set Table.

2.2.2.  Inputs

  Input sub-units are mechanisms that feed media to be marked on into
  the printer. A printer contains one or more input sub-units. These
  are represented by the Input Group in the model. The model does not
  distinguish fixed input bins from removable trays, except to report
  when a removable tray has been removed.

  There are as many input sub-units as there are distinctly selectable
  input "addresses".  For example, if a tray has an option for manually
  feeding paper as well as automatically feeding from the tray, then
  this is two input sub-units if these two sources can be (must be)
  separately selected and is one input sub-unit if putting a sheet in
  the manual feed slot overrides feeding from the contents of the tray;
  that is, in the second case there is no way to separately select or
  address the manual feed slot.

2.2.3.  Media

  An input sub-unit can hold one or more instances of the media on
  which marking is to be done. Typically, there is a large set of
  possible media that can be associated with an input. The Media Group
  is an extension of the Input Group which represents that media that
  is in an input sub-unit. The Media Group only describes the current
  contents of each input and not the possible content of the input
  sub-unit.

2.2.4.  Outputs

  Output sub-units are mechanisms that receive media that has been
  marked on. A printer contains one or more output mechanisms. These
  are represented by the Output Group in the model. The model does not
  distinguish fixed output bins from removable output bins, except to
  report when a removable bin has been removed.

  There are as many output sub-units as there are distinctly selectable
  output "addresses".  Output sub-units can be addressed in two



Smith, Wright, Hastings, Zilles & Gyllenskog                    [Page 9]

RFC 1759                      Printer MIB                     March 1995


  different ways: (1) as a set of "mailboxes" which are addressed by a
  specific mailbox selector such as a bin number or a bin name, or (2)
  as a set of "slots" into which multiple copies are collated.
  Sometimes both modes of using the output sub-units can be used on the
  same printer.  All that is important from the viewpoint of the model
  is that the output units can be separately selected.

2.2.5.  Finishers

  A finisher is a sub-unit that performs some operations on the media
  other than marking.  The finisher sub-units are represented by the
  Finisher Group in the model.  Some examples of finishing processes
  are stapling, punching, binding, inserting, or folding.  Finishing
  processes may have supplies asssociated with the process.  Stapling,
  binding, and punching are examples of processes that have supplies. A
  printer may have more than one finishing sub-unit and each finishing
  sub-unit may be associated with one or more output sub-units.
  Finishers are not described in this MIB.

  The exact interaction and sequencing between an output device and its
  associated finisher is not specified by the model. It depends on the
  type of finishing process and the exact implementation of the printer
  system. This standard allows for the logical association of a
  finishing process with an output device but does not put any
  restrictions on the exact sequence or interaction with the associated
  output device. The output and finisher sub-units may or may not be
  separate identifiable physical mechanisms depending on the exact
  implementation of a printer.  In addition, a single output device may
  be associated with multiple finishing sub-units and a single
  finishing sub-unit may be associated with multiple output devices.

2.2.6.  Markers

  A marker is the mechanism that produces marks on the print media. The
  marker sub-units and their associated supplies are represented by the
  Marker Group in the model. A printer can contain one or more marking
  mechanisms.  Some examples of multiple marker sub-units are: a
  printer with separate markers for normal and magnetic ink or an
  imagesetter that can output to both a proofing device and final film.
  Each marking device can have its own set of  characteristics
  associated with it, such as marking technology and resolution.

  In this model the marker sub-unit is viewed as very generalized and
  encompasses all aspects of a marking process. For example, in a
  xero-graphic process, the marking process as well as the fusing
  process would be included in the generalized concept of the marker.
  With the generalized concept of a marking process, the concept of
  multiple marking supplies associated with a single marking sub-unit



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 10]

RFC 1759                      Printer MIB                     March 1995


  results. For example, in the xerographic process, there is not only a
  supply of toner, but there can also be other supplies such as a fuser
  supply that can be consumed and replaced separately. In addition
  there can be multiple supplies of toner for a single marker device,
  as in a color process.

2.2.7.  Media Paths

  The media paths encompass the mechanisms in the printer that move the
  media through the printer and connect all other media related sub-
  units: inputs, outputs, markers and finishers. A printer contains one
  or more media paths. These are represented by the Media Path Group in
  the model.  The Media Path group has some objects that apply to all
  paths plus a table of the separate media paths.

  In general, the design of the media paths determines the maximum
  speed of the printer as well as the maximum media size that the
  printer can handle. Media paths are complex mechanisms and can
  contain many different identifiable sub-mechanisms such as media
  movement devices, media buffers, duplexing units and interlocks. Not
  all of the various sub-mechanisms reside on every media path.  For
  example, one media path may provide printing only on one surface of
  the media (a simplex path) and another media path may have a sub-
  mechanism that turns the media over and feeds it a second time
  through the marker sub-unit (a duplex path).  The duplex path may
  even have a buffer sub-mechanism that allows multiple copies of the
  obverse side to be held before the reverse side of all the copies are
  marked.

2.2.8.  System Controller

  The System Controller is the sub-unit upon which the software
  components of the Printer run. The System Controller is represented
  in the model by the Host MIB. This MIB allows for the specification
  of the processor(s), memory, disk storage, file system and other
  underlying sub-mechanisms of the printer. The controller can range
  from simple single processor systems to multiprocessor systems. In
  addition, controllers can have a full range of resources such as hard
  disks. The printer is modeled to have one system controller even
  though it may have more than one processor and multiple other
  resources associated with it.

2.2.9.  Interfaces

  An interface is the communications port and associated protocols that
  are responsible for the transport of data to the printer. A printer
  has one or more interface sub-units. The interfaces are represented
  by the Interfaces Group of MIB-II (RFC 1213). Some examples of



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 11]

RFC 1759                      Printer MIB                     March 1995


  interfaces are serial ports (with little or no protocol) and EtherNet
  ports on which one might run InterNet IP, Novell IPX, etc.

2.2.10.  Channels

  The channel sub-units identify the independent sources of print data
  (here print data is the information that is used to construct printed
  pages and may have both data and control aspects).  A printer may
  have one or more channels. The channel sub-units are represented by
  the Channel Group in the Model. Each channel is typically identified
  by the electronic path and service protocol used to deliver print
  data to the printer. A channel sub-unit may be independently enabled
  (allowing print data to flow) or disabled (stopping the flow of print
  data). It has a current Control Language which can be used to specify
  which interpreter is to be used for the print data and to query and
  change environment variables used by the interpreters (and SNMP).
  There is also a default interpreter that is to be used if an
  interpreter is not explicitly specified using the Control Language.
  Channel sub-units are based on an underlying interface.

2.2.11.  Interpreters

  The interpreter sub-units are responsible for the conversion of a
  description of intended print instances into images that are to be
  marked on the media. A printer may have one or more interpreters. The
  interpreter sub-units are represented by the Interpreter Group in the
  Model. Each interpreter is generally implemented with software
  running on the System Controller sub-unit. The Interpreter Table has
  one entry per interpreter where the interpreters include both Page
  Description Language (PDL) Interpreters and Control Language
  Interpreters.

2.2.12.  Console

  Many printers have a console on the printer, the operator console,
  that is used to display and modify the state of the printer.  The
  console can be as simple as a few indicators and switches or as
  complicated as full screen displays and keyboards. There can be at
  most one such console.  This console sub-unit is represented by the
  Console Group in the model.  Although most of the information
  displayed there is also available in the state of the printer as
  represented by the various Groups, it is useful to be able to query
  and modify the operator console remotely.  For example, a management
  application might like to display to its user the current message on
  the operator console of the remote printer or the management
  application user might like to modify the current message on the
  operators console of the remote printer.  As another example, one
  might have a remote application that puts up a pseudo console on a

RFC 1759                      Printer MIB                     March 1995


  workstation screen. Since the rules by which the printer state is
  mapped onto the console and vice versa are not standardized, it is
  not possible to reproduce the console state or the action of console
  buttons and menus. Therefore, the Console Group provides access to
  the console. The operator console is usually implemented on the
  system controller with additional hardware for input and display.

2.2.13.  Alerts

  The alert sub-unit is responsible for detecting reportable events,
  making an entry in the alert table and, if and only if the event is a
  critical event, initiating a trap. The alert sub-unit is represented
  by the Alerts Group and, in particular, the Alert Table. This table
  contains information on the severity, sub-unit, detailed location
  within the sub-unit, alert code and description of each critical
  alert that is currently active within the printer. Each reportable
  event causes an entry to be made in the Alert Table.

2.2.13.1.  Status and Alerts

  Summary information about the state of the printer is reported at
  three separate levels: (1) there is the status of the printer as a
  whole reported in the Host MIB, (2) there is the status of various
  sub-units reported in the principle table of the Group that
  represents the sub-unit, and (3) there are alert codes reported in
  the Alert Table.

2.2.13.2.  Overall Printer Status

  Of the many states a printer can be in, certain states are more
  "interesting" because of the distinct actions they are likely to
  provoke in the administrator.  These states may be applied to the
  printer as a whole, or to a particular sub-unit of the printer.
  These named states are:

  Non Critical Alert Active - For the printer this means that one or
  more sub-units have a non-critical alert active.  For a sub-unit,
  this means that the sub-unit has a non-critical alert active.

  Critical Alert Active - For the printer this means that one or more
  sub-units have a critical alert active.  For a sub-unit, this means
  that the sub-unit has a critical alert active.

  Unavailable - The printer or sub-unit is unavailable for use (this is
  the same as "broken" or "down" in other terminologies).  A trained
  service person is typically necessary to make it available.





Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 13]

RFC 1759                      Printer MIB                     March 1995


  Busy / Temporarily Unavailable - The printer or sub-unit is
  operational but currently occupied with a request for activity. The
  sub-unit will become available without the need of human interaction.

  Moving on-line or off-line - The printer is either off-line, in the
  process of moving off-line or in the process of moving back on-line;
  for example on high end printers reloading paper involves a
  transition to off-line to open the paper bin, it is then filled and,
  finally, there is a transition back to on-line as the paper bin is
  repositioned for printing.

  Standby - The printer or sub-unit is unavailable for use because it
  is partially powered down and may need some period of time to become
  fully operational again.  A unit in Standby state shall respond to
  network management requests.

  The Host MIB provides three status objects that can be used to
  describe the status of a printer: (1) hrDeviceStatus in the entry in
  the Host MIB hrDeviceTable; (2) hrPrinterStatus in the
  hrPrinterTable; and (3) hrPrinterDetectedErrorState in the
  hrPrinterTable.  These objects describe many of the states that a
  printer can be in.  The following table shows how the "interesting"
  states named above can be recognized by inspecting the values of the
  three printer-related objects in the Host MIB:

Printer     hrDeviceStatus  hrPrinterStatus  hrPrinterDetectedErrorState
Status

Normal         running(2)     idle(3)        none set

Busy/          running(2)     printing(4)
Temporarily

Alert Active                  printing(4)    lowToner, or
                                            serviceRequested

Critical       down(5)        other(1)       could be: jammed,
Alert Active                                 noPaper, noToner,
                                            coverOpen, or
                                            serviceRequested

Off-line       down(5)        other(1)       offline

Moving         down(5)        warmup(5)
on-line

Standby        running(2)     other(1)

  These named states are only a subset of the possible states - they
  are not an exhaustive list of the possible states.  Nevertheless,
  several things should be noted.  When using these states, it is not
  possible to detect when both critical and non-critical alerts are
  pending - if both are pending, the Critical Alert Active state will
  prevail.  In addition, a printer in the Standby state will be
  represented in the Host MIB with a device status of running(2) and a
  printer status of other(1), a set of states that don't uniquely
  distinguish this important printer state.

  Although the above mapping is workable, it would be improved with a
  few additions to hrDeviceStatus and hrPrinterStatus in the Host
  Resources MIB. In particular, it would be appropriate to add a
  "standby" enumeration to hrDeviceStatus.  Similarly, it would be
  useful to add the following states to hrPrinterStatus: "offline" to
  indicate that reason for the printer being down (instead of having to
  use "other") which allows both "warning" and "offline" to indicate
  going offline and "down" and "offline" to indicate offline and
  "notApplicable" to cover cases, such as "standby", where the device
  state completely describes the state of the device.

  Detailed status per sub-unit is reported in the sub-unit status
  fields.

                (e.g., a disk device driver) but that the device is
                still 'operational'.  An example would be high

2.2.13.2.2.  Sub-unit Status

  Sub-unit status is reported in the entries of the principle table in
  the Group that represents the sub-unit. For sub-units that report a
  status, there is a status column in the table and the value of this
  column is always an integer formed in the following way.

  The SubUnitStatus is an integer that is the sum of 5 distinct values,
  Availability, Non-Critical, Critical, On-line, and Transitioning.
  These values are:

    Availability                           value

           Available and Idle              0       000'b
           Available and Standby           2       010'b
           Available and Active            4       100'b
           Available and Busy              6       110'b
           Unavailable and OnRequest       1       001'b

           Intended state is Off-Line      32

   Transitioning

           At intended state               0
           Transitioning to intended state 64

  For example, an input (tray) that jammed on the next to the last page
  may show a status of 27 (unavailable because broken (3) + a critical
  state (16), jammed, and a noncritical state (8), low paper).

2.2.13.3.  Alert Tables

  The Alert Group consists of a single table in which all active alerts
  are represented.  This section provides and overview of the table and
  a description of how it is managed.  The basic content of the alert
  table is the severity (critical or non-critical) of the alert, the
  Group and entry where a state change caused the alert, additional
  information about the alert (a more detailed location, an alert code,
  and a description), and an indication of the level of training needed
  to service the alert.

  The Alert Table contains some information that is redundant, for
  example that an event has occurred, and some information that is only
  represented in the Alert Table, for example the additional
  information.  A single table was used because a single entry in a
  Group could cause more than one alert, for example paper jams in more
  than one place in a media path. Associating the additional
  information with the entry in the affected group would only allow one
  report where associating the additional information with the alert
  makes multiple reports possible.




Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 18]

RFC 1759                      Printer MIB                     March 1995


  Every time an alert occurs in the printer, the printer makes one or
  more entries into the Alert Table. The printer determines if an event
  is to be classified as critical or non-critical. If the severity of
  the Alert is "critical", the printer sends a trap or event
  notification to the host indicating that the table has changed.
  Whether or not a trap is sent, the management application is expected
  to poll the printer on a regular basis and to read and parse the
  table to determine what conditions have changed, in order to provide
  reliable information to the management application user.

2.2.13.4.  Alert Table Management

  The alert tables are sparsely populated tables. This means the tables
  will only contain entries of the alerts that are currently active and
  the number of rows, or entries in the table will be dynamic. More
  than one event can be added or removed from the event tables at a
  time depending on the implementation of the printer.

  There are basically two kinds of events that produce alerts: binary
  change events and simple change events. Binary change events come in
  pairs: the leading edge event and the trailing edge event. The
  leading edge event enters a state from which there is only one exit;
  for example, going from running to stopped with a paper jam. The only
  exit from this state is fixing the paper jam and it is clear when
  that is accomplished.  The trailing edge event is the event which
  exits the state the was entered by the leading edge event; in the
  example above fixing the paper jam is the trailing edge event.

  It is relatively straightforward to manage binary change events in
  the Alert Table. Only the leading edge event makes an entry in the
  alert table.  This entry persists in the Alert Table until the
  trailing edge event occurs at which point this event is signal by the
  removal of the leading edge event entry in the Alert Table.  That is,
  a trailing edge event does not create an entry; it removes the
  corresponding leading edge event. With binary events it is possible
  to compute the maximum number that can occur at the same time and
  construct an Alert Table that would hold that many events. There
  would be no possibility of table overflow and no information about
  outstanding events would be lost.

  Unfortunately, there are some events that are not binary changes.
  This other category of event, the simple change event,  is
  illustrated by the configuration change event. With this kind of
  event the state of the machine has changed, but to a state which is
  (often) just as valid as the state that was left and from which no
  return is necessary.  For example, an operator may change the paper
  that is in the primary input source from letter to legal. At some
  time in the future the paper may be changed back to letter, but it



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 19]

RFC 1759                      Printer MIB                     March 1995


  might be changed to executive instead.  This is where the problem
  occurs. It is not obvious how long to keep simple change event
  entries in the Alert Table. It they were never removed, the Alert
  Table would continue to grow indefinitely.

  The agent needs to have an algorithm implemented for the management
  of the alert table, especially in the face of combinations of binary
  and simple alerts that would overflow the storage capaciity of the
  table.  When the table is full and a new alert needs to be added, an
  old alert needs to be deleted.  The alert to be deleted should be
  chosen using the following rules:

   1. Find a non-critical simple alert and delete it.  If there are
      multiple non-critical simple alerts, it is suggested that the
      oldest one be chosen.  If there are no non-critical simple
      alerts, then,

   2. Find a non-critical binary alert and delete it.  If there are
      multiple non-critical binary alerts, it is suggested that the
      oldest one be chosen.  If there are no non-critical binary
      alerts, then,

   3. Find a critical (binary) alert and delete it.  If there are
      multiple critical alerts, it is suggested that the
      oldest one be chosen.  Agent implementors are encouraged to
      provide at least enough storage space for the maximum number
      of critical alerts that could occur simultaneously.  Note that
      all critical alerts are binary.

  Note that because the Alert Index is a monotonically increasing
  integer there will be gaps in the values in the table when an alert
  is deleted.  Such gaps can be detected by the management application
  to indicate that the management application may want to re-acquire
  the Printer state and check for state changes it did not observe in
  the Alert Table.

2.3.  Read-Write Objects

  Some of the objects in the printer MIB report on the existence of or
  amount of a given resource used with the printer.  Some examples of
  such resources are the size and number of sheets of paper in a paper
  tray or the existence of certain output options.  On some printers
  there are sensors that allow these resources to be sensed.  Other
  printers, however, lack sensors that can detect (all of) the
  properties of the resource.  Because the printer needs to know of the
  existence or properties of these resources for the printer to
  function properly some other way of providing this information is
  needed.  The chosen way to solve this problem is to allow a



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 20]

RFC 1759                      Printer MIB                     March 1995


  management application to write into objects which hold the
  descriptive or existence values for printers that cannot sense the
  values.  Thus many of the objects in the MIB are given read-write
  access, but a printer implementation might only permit a management
  operation to change the value if the printer could not sense the
  value itself.  Therefore, the ability to change the value of a read-
  write object may depend on the implementation of the agent.  Note
  that even though some objects explicitely state the behaviour of
  conditional ability to change values, any read-write object may act
  that way.

  Generally, an object is given read-write access in the Printer MIB
  specification if:

 1.The object involves installation of a resource that some
   printers cannot themselves detect.  Therefore, external means are
   needed to inform the printer of the installation.  (Here external
   means include using the operator console, or remote management
   application) and

 2.The printer will behave differently if the installation of the
   resource is reported than the printer would if the installation
   were not reported; that is, the object is not to be used
   as a place to put information not used by the printer, i.e., not a
   "PostIt".  Another way of saying this is that the printer believes
   that information given it and acts as if the information were
   true.  For example, on a printer that cannot sense the size, if
   one paper size is loaded, but another size is set into the paper
   size object, then the printer will use the size that was
   set as its current paper size in its imaging and paper handling.

  The printer may get hints that it may not know about the existence or
  properties of certain resources.  For example, a paper tray may be
  removed and re-inserted.  When this removal and insertion happens,
  the printer may either assume that a property, such as the size of
  paper in the tray, has not changed or the printer may change the
  value of the associated object to "unknown", as might be done for the
  amount of paper in the tray.  As long as the printer acts according
  to the value in  the object either strategy is acceptable.

  It is an implementation-specific matter as to whether or not MIB
  object values are persistent across power cycles or cold starts.  It
  is particularly important that the values of the prtMarkerLifeCount
  object persist throughout the lifetime of the printer.  Therefore, if
  the value of any MIB object persists across power cycles, then the
  prtMarkerLifeCount object must also persist.

2.4.  Enumerations

  Enumerations (enums) are sets of symbolic values defined for use with
  one or more objects.  Some common enumeration sets are assigned a
  symbolic data type name (textual convention).  These enumerations are
  listed at the beginning of this specification.

2.4.1.  Registering Additional Enumerated Values

  This working group has defined several type of enumerations.  These
  enumerations differ in the method employed to control the addition of
  new enumerations.  Throughout this document, references to
  "enumeration (n)", where n can be 1, 2 or 3 can be found in the
  various tables.  The definitions of these types of enumerations are:

 enumeration (1)  All the values are defined in the Printer MIB
    specification (RFC for the Printer MIB).  Additional enumerated
    values require a new RFC.

 enumeration (2)  An initial set of values are defined in the Printer
    MIB specification.  Additional enumerated values are
    registered after review by this working group. The initial
    versions of the MIB will contain the values registered so far.
    After the MIB is approved, additional values will be
    registered through IANA after approval by this working group.

 enumeration (3)  An initial set of values are defined in the Printer
    MIB specification.  Additional enumerated values are
    registered without working group review.  The initial versions of
    the MIB will contain the values registered so far.  After the MIB
    is approved, additional values will be registered
    through IANA without approval by this working group.

3.  Objects from other MIB Specifications

  This section lists the objects from other IETF MIB specifications
  that are mandatory for conformance to this Printer MIB specification.

3.1.  System Group objects

  All objects in the system group of MIB-II (RFC 1213) must be
  implemented.

3.2.  System Controller

  The System Controller is represented by the Storage and Device Groups
  of the Host Resources MIB (RFC 1514).  These are the only groups that
  are required to be implemented.  Other Groups (System, Running
  Software, Running Software Performance, and Installed Software) may
  be implemented at the discretion of the implementor.

3.3.  Interface Group objects

  All objects in the Interfaces Group of MIB-II (RFC 1213) shall be

 CodedCharSet ::= TEXTUAL-CONVENTION
     STATUS     current
     DESCRIPTION
        "A coded character set value that specifies both a set of
         characters that may be used and an encoding (as one or more
         octets) that is used to represent the characters in the
         set. These values are to be used to identify the encoding
         employed for strings in the MIB where this is not fixed by
         the MIB.

         Some objects that allow a choice of coded character set
         are: the prtLocalizationCharacterSet object in the
         LocalizationTable and prtInterpreterDefaultCharSetIn.
         The prtGeneralCurrentLocalization and prtConsoleLocalization
         objects in turn contain the index in the LocalizationTable
         of the current localization (country, language, and coded
         character set) of the `description' objects and the console,
         respectively.

         The space of the coded character set enumeration has been
         divide into three regions. The first region (3-999) consists
         of coded character sets that have been standardized by some
         standard setting organization. This region is intended for
         standards that do not have subset implementations. The
         second region (1000-1999) is for the Unicode and ISO/IEC 10646
         coded character sets together with a specification of a (set
         of) sub-repetoires that may occur.  The third region (>1999)
         is intended for vendor specific coded character sets.



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 25]

RFC 1759                      Printer MIB                     March 1995


         NOTE: Unicode and ISO 10646 character coded data may be
         processed and stored in either Big Endian (most significant
         octet first) or Little Endian (least significant octet
         first) order.  Intel x86, VAX, and Alpha/AXP architectures are
         examples of Little Endian processor architectures.
         Furthermore, in environments where either order may occur,
         so-called Unicode BYTE ORDER MARK (BOM) character (which is
         ISO 10646 ZERO WIDTH NO BREAK SPACE), coded as FEFF in two
         octets and 0000FEFF in four octets is used at the beginning
         of the data as a signature to indicate the order of the
         following data (See ISO 10646 Annex F).  Thus either
         ordering and BOM may occur in print data streams sent to the
         interpreter.  However, ISO 8824/8825 (ASN.1/BER) used by
         SNMP is quite clear that Big Endian order shall be used and
         BOM shall NOT be used in transmission in the protocol.
         Transmitting Unicode in Big Endian order in SNMP should
         not prove to be a hardship for Little Endian machines,
         since SNMP ASN.1/BER requires integers to be transmitted
         in Big Endian order as well.  So SNMP implementations on
         Little Endian machines are already reversing the order of
         integers to make them Big Endian for transmission via
         SNMP.  Also Unicode characters are usually treated as
         two-octet integers, not short text strings, so that it will
         be straightforward for Little Endian machines to reverse the
         order of Unicode character octets as well before
         transmitting them and after receiving them via the SNMP
         protocol.

         Where a given coded character set may be known by more than
         one name, the most commonly known name is used as the name
         of the enumeration and other names are shown in the
         comments.  The comments also indicate where to find detailed
         information on the coded character set and briefly
         characterize its relationship to other similar coded
         character sets.

         The current list of character sets and their enumerated
         values used to reference them is contained in the IANA
         Character Set registry.  The enum value is indicated by
         the MIBenum entry in the registry.  The enum symbol is
         indicated by the Alias that starts with `cs' for character
         set.

         The IANA character sets registry is available via
         anonymous ftp.

         The ftp server is ftp.isi.edu.
         The subdirectory is /in-notes/iana/assignments/.

-- The Channel Group
--
-- Implementation of every object in this group is mandatory.

-- Channels are independent sources of print data. Here,
-- print data is the term used for the information that is
-- used to construct printed pages and may have both data
-- and control aspects. The output of a channel is in a form
-- suitable for input to one of the interpreters as a
-- stream. A channel may be independently enabled (allowing
-- print data to flow) or disabled (stopping the flow of
-- print data). A printer may have one or more channels.
--
-- Basically, the channel abstraction is intended to cover
-- all the aspects of getting the print data to an
-- interpreter. This might include transporting the data
-- from one place to another, it might include (invisible)
-- compression, it might include encoding or packetizing to
-- provide multiple information sources over a single
-- physical interface and it might include filtering
-- characters that were destined for another kind of
-- channel. All of these aspects are hidden in the channel
-- abstraction.(Note some Page Description Languages have
-- compression built into them so "invisible" compression
-- refers to compression done by the transport medium and
-- removed before the data is presented to the interpreter.)
--
-- There are many kinds of channels;some of which are based
-- on networks and others which are not. For example, a
-- channel can be a serial (or parallel) connection; it can
-- be a service, such as the Unix Line Printer Daemon (LPD),
-- offering itself over a network connection (interface); or
-- it could be a disk drive into which a floppy disks with
-- the print data is inserted. Each channel is typically
-- identified by the electronic path and/or service protocol
-- used to deliver print data to the printer.
--
-- Channel example                   Implementation
--
-- serial port channel            bi-directional data channel
-- parallel port channel          often uni-directional channel
-- IEEE 1284 port channel         bi-directional channel
-- SCSI port channel              bi-directional
-- Apple PAP channel              may be based on Local-, Ether-or
--                                TokenTalk
-- LPD Server channel             typically TCP/IP based, port 515

RFC 1759                      Printer MIB                     March 1995


-- Novell Remote Printer          typically SPX/IPX based channel
-- Novell Print Server            typically SPX/IPX based channel
-- port 9100 channel              HP and friends
-- Adobe AppSocket(9101) channel  a bi-directional extension of LPD
--
-- It is easy to note that this is a mixed bag.  There are
-- some physical connections over which no (or very meager)
-- protocols are run (e.g. the serial or old parallel ports)
-- and there are services which often have elaborate
-- protocols that run over a number of protocol stacks. In
-- the end what is important is the delivery of print data
-- thru the channel.
--
-- The channel sub-units are represented by the Channel
-- Group in the Model. It has a current Control Language
-- which can be used to specify which interpreter is to be
-- used for the print data and to query and change
-- environment variables used by the interpreters (and
-- Mangement Applications). There is also a default
-- interpreter that is to be used if an interpreter is not
-- explicitly specified using the Control Language. Channel
-- sub-units are based on an underlying interface.

--       The channel table and its underlying structure
--
-- The first seven items in the Channel Table define the
-- "channel" itself.  A channel typically depends on other
-- protocols and interfaces to provide the data that flows
-- thru the channel. It is necessary to provide control of
-- the (perhaps complex) process by which print data arrives
-- at an interpreter. Control is largely limited to enabling
-- or disabling the whole channel. It is likely, however,
-- that more control of the process of accessing print data
-- will be needed over time. Thus, the ChannelType will
-- allow type specific data to be associated with each
-- channel (using ChannelType specific groups in a fashion
-- analogous to the media specific MIBs that are associated
-- with the IANAIfType in the Interfaces Table). As a first
-- step in this direction, each channel will identify the
-- underlying Interface on which it is based. This is the
-- eighth object in each row of the table.

-- Some examples of the kind of control are where
-- compression or encoding is used; and whether the data is
-- filtered to remove file storage anomolies such as those
-- created by using MS-DOS/PC-DOS LPT1:.

Appendix A - Glossary of Terms

  Addressability -- on the marker, the number of distinctly setable
  marking units (pels) per unit of addressability unit; for example,
  300 dots per inch is expressed as 300 per 1000 Thousandths Of Inches
  and 4 dots per millimeter is 4 per 1000 Micrometers. Addressability
  is not resolution because marks that are one addressability position
  apart may not be independently resolvable by the eye due to factors
  such as gain in the area of marks so they overlap or nearly touch.

  Alert -- a reportable event for which there is an entry in the alert
  table

  Bin -- an output sub-unit which may or may not be removable

  Bursting -- the process by which continuous media is separated into
  individual sheets, typically by bursting along pre-formed
  perforations.

  Channel -- A term used to describe a single source of data which is
  presented to a printer.  The model that we use in describing a
  printer allows for an arbitrary number of channels.  Multiple
  channels can exist on the same physical port.  This is commonly done
  over EtherNet ports where EtherTalk, TCP/IP, and SPX/IPX protocols
  can be supplying different data streams simultaneously to a single
  printer on the same physical port.

  Collation -- in multiple copy output, placing the pages from separate
  copies into separte output bins

  Control Language - a data syntax or language for controlling the
  printer through the print data channel.

  Critical Alert -- an alert triggered by an event which leads to a
  state in which printing is no longer possible; the printer is stopped

  Decollating -- the process by which the individual parts within a
  multi-part form are separated and sorted into separate stacks for
  each part.

  Description -- information about the configuration and capabilities
  of the printer and its various sub-units

  DPA - ISO 10175 Document Printing Application standard.  A standard
  for a client server protocol for a print system, including (1)
  submitting print jobs to and (2) managing print jobs in a spooler

  Event - a state change in the printer



Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 98]

RFC 1759                      Printer MIB                     March 1995


  Group -- a collection of objects that represent a type of sub-unit of
  the printer

  IANA - Internet Assigned Numbers Authority.  See STD 2, RFC 1700.

  Idempotent -- Idempotence is the property of an operation that
  results in the same state no matter how many times it is executed (at
  least once).  This is a property that is shared by true databases in
  which operations on data items only change the state of the data item
  and do not have other side effects.  Because the SNMP data model is
  that of operations on a database, SNMP MIB objects should be assumed
  to be idempotent.  If a MIB object is defined in a non-idempotent
  way, the this data model can break in subtle ways when faced with
  packet loss, multiple managers, and other common conditions.

  In order to fulfill the common need for actions to result from SNMP
  Set operations, SNMP MIB objects can be modeled such that the change
  in state from one state to another has the side effect of causing an
  action.  It is important to note that with this model, an SNMP
  operation that sets a value equal to its current value will cause no
  action.  This retains the idempotence of a single command, while
  allowing actions to be initiated by SNMP SET requests.

  For example, a switch like the foot switch that changes from high
  beams to low beams is not idempotent. If the command is received
  multiple times the result may be different than if the command was
  received a single time.  In the SNMP world preferred commands would
  be "set lights to high beam" and "set lights to low beam".  These
  commands yield predictable results when executed perhaps multiple
  times.  A command like "press foot toggle switch", is not idempotent
  because when executed an unknown number of times, it yields an
  indeterminate result.

  Input -- a tray or bin from which instances of the media are obtained
  and fed into the Media Path

  Interpreter - the embodiment of an algorithm that processes a data
  stream consisting of a Page Description Language (PDL) and/or a
  Control Language.

  Localization -- the specification of human language, country, and
  character set needed to present information to people in their native
  languages.

  Management Application (a.k.a. Manager) -- a program which queries
  and controls one or more managed nodes





Smith, Wright, Hastings, Zilles & Gyllenskog                   [Page 99]

RFC 1759                      Printer MIB                     March 1995


  Management Station -- a physical computer on which one or more
  management applications can run

  Media Path -- the mechanisms that transport instances of the media
  from an input, through the marker, possibly through media buffers and
  duplexing pathways, out to the output with optional finishing
  applied.  The inputs and outputs are not part of the Media Path.

  MIB - Management Information Base - the specification for a set of
  management objects to be managed using SNMP or other management
  protocol; also an instance of the data for such a set

  Non-critical Alert -- an alert triggered by a reportable event which
  does not lead to a state in which printing is no longer possible;
  such an alert may lead to a state from which printing may no longer
  be possible in the future, such as the low toner state or the alert
  may be pure informational, such as a configuration change at the
  printer.

  Object - a data item that has a name, a syntax, and a value.  usage).

  Output -- a bin or stacker which accepts instances of media that have
  been processed by a printer

  Page Description Language (PDL) - a data syntax or language for the
  electronic representation of a document as a sequence of page images.

  Printer -- a physical device that takes media from an input source,
  produces marks on that media according to some page description or
  page control language and puts the result in some output destination,
  possibly with finishing applied.

  Printing -- the entire process of producing a printed document from
  gen- eration of the file to be printed, choosing printing properties,
  selection of a printer, routing, queuing, resource management,
  scheduling, and finally printing including notifying the user

  Reportable event -- an event that is deemed of interest to a
  management station watching the printer

  Status -- information regarding the current operating state of the
  printer and its various sub-units. This is an abstraction of the
  exact physical condition of the printer.

  Sub-mechanism -- a distinguishable part of a sub-unit

  Sub-unit -- a part of the printer which may be a physical part, such
  as one of the input sources or a logical part such as an interpreter.

Appendix B - Media Size Names from ISO/IEC 10175 Document Printing
            Architecture

  For the convenience of management application developers, this
  appendix lists the standardized media size names from ISO/IEC 10175
  Document Printing Application (DPA). Management applications that
  present a dialogue for choosing or displaying media size are
  encouraged to present relevant names from this list to avoid
  requiring the user to remember the physical dimensions used to
  describe the size of the media. A printer implementing the Printer
  MIB has no knowledge of these names, however; all media sizes in the
  MIB are given in terms of media dimensions as the values of
  prtInputChosenMediaDimFeedDir and prtInputChosen-MediaDimXFeedDir.

Appendix C - Media Names

  For the convenience of management application developers, this
  appendix lists the standardized media names from ISO/IEC 10175
  Document Printing Application (DPA). Management applications that
  present a dialogue for choosing media may wish to use these names as
  an alternative to separately specifying, size, color, and/or type.
  Using standard media names will mean that a single management
  application dealing with printers from different vendors and under
  different system mangers will tend to use the same names for the same
  media. If selection of media by name is used, the attributes (size,
  type or color) implied by the name must be explicitly mapped to the
  appropriate object (prtInputDeclared-MediaDimFeedDir,
  prtInputDeclaredMediaDimXFeedDir, prtInputMediaType and
  prtInputMediaColor) in the MIB. The object prtInputMediaName is
  intended for display to an operator and is purely descriptive. The
  value in prtInputMediaName is not interpreted by the printer so using
  a standard name for this value will not change any of the other media
  attributes nor will it cause an alert if the media in the input sub-
  unit does not match the name.

Appendix D - Roles of Users

Background

  The need for Role Models stemmed in large part from the need to
  understand the importance any given managed object under
  consideration for inclusion in the specification.  Many times the
  presence or nature of a particular proposed object would be debated
  within the group; the debate would typically end when one or more
  persons would describe the potential usage for the object, usually in
  terms of a "live" person operating in some target environment.

  Steve Zilles (Adobe) first mentioned that he had considered this
  general problem and had come up with a short list of categories by
  which the group can evaluate the relative utility of a proposed
  object.  The list Steve described was:

   - User

   - Trained Operator

   - Service

  Upon further examination of the overall problem I found it useful to
  expand the list of categories, as well as attempt to define a basic
  set of "requirements areas" that can help define the basic nature of
  each category.

  Every concept needs a name, and this concept is no different.  For
  lack of better alternatives, I refer to these categories as "Role
  Models" in this document.  This name was chosen in light of the fact
  that many times we try to find a "person" (or similar entity) for
  which the use of a proposed object is targeted.  (I resisted the
  temptation to use the term "Usage Models," as I felt the term was too
  generic in nature.)

  In presenting the initial list of Role Models, the initial set of
  "requirements areas" are presented, followed by the set of Role Model
  definitions.  Finally, a simple matrix is presented in which Role
  Models and requirements areas are cross-compared.

  It should be emphasized at this point that all of this is proposed as
  initial information for further discussion.  No doubt major changes

RFC 1759                      Printer MIB                     March 1995


  will be proposed by members of the group as time goes on.

Proposed Print System Requirements Areas

  Surrounding printers and printing systems, the following list of
  "requirement areas" is proposed as a "check list" of needs for the
  various Role Models:

 Printer job state - Determine the status of a job without a printer.
 Printer capabilities - Determine the current capabilities of a
    printer, for example, the available media sizes, two-sided
    printing, a particular type of interpreter, etc.
 Printer job submission - Submit a print job to a printer.
 Printer job removal - Remove a job from a printer.
 Notification of events - Receive notification of the existence of a
    defined printer event.  An event can be of many types, including
    warnings, errors, job stage completion (e.g., "job done"), etc.
 Printer configuration - Query the current configuration of a
    printer.
 Printer consumables - Determine the current state of any and all
    consumables within a printer.
 Print job identification - Determine the identification of a job
    within a printer.
 Internal printer status - Determine the current status of the
    printer.
 Printer identification - Determine the identify of a printer.
 Printer location - Determine the physical location of a printer.
 Local system configuration - Determine various aspects of the
    current configuration of the local system involved with the
    operation of a printer.

  These "requirements" cover a large spectrum of requirements
  surrounding the operation of a printer in a network environment.
  This list is by no means complete, but serves as a starting point for
  assessing major requirements of the various Role Models described
  below.

Proposed Role Models

  Following is a proposed list of "Role Models" to be used in
  evaluating the requirements for any given object defined within the
  Printer MIB.  Note that the keyword enclosed in parentheses
  represents an abbreviation for the particular Role Model in the
  matrix described later in this document.

 User  (USER) - A person or application that submits print jobs to
    the printer; typically viewed as the "end user" within the overall
    printing environment.



Smith, Wright, Hastings, Zilles & Gyllenskog                  [Page 108]

RFC 1759                      Printer MIB                     March 1995


 Operator  (OP) - A person responsible for maintaining a printer on a
    day-to-day basis, including such tasks as filling empty media
    trays, emptying full output trays, replacing toner cartridges,
    etc.
 Technician  (TECH) - A person responsible for repairing a
    malfunctioning printer, performing routine preventive maintenance,
    and other tasks that typically require advanced training on the
    printer internals.  An example of a "technician" would be a
    manufacturer's Field Service representative, or other person
    formally trained by the manufacturer or similar representative.
 System Manager  (MGR) - A person responsible for configuration and
    troubleshooting of components involved in the overall printing
    environment, including printers, print queues and network
    connectivity issues.  This person is typically responsible for
    ensuring the overall operational integrity of the print system
    components, and is typically viewed as the central point of
    coordination among all other Role Models.
 Help Desk  (HELP) - A person responsible for supporting Users in
    their printing needs, including training Users and troubleshooting
    Users' printing problems.
 Asset Manager  (AM) - A person responsible for managing an
    organizations printing system assets (primarily printers).  Such a
    person needs to be able to identify and track the location of
    printing assets on an ongoing basis.
 Capacity Planner  (CP) - A person responsible for tracking the usage
    of printing resources on an ongoing basis.  An optional related
    activity might be to acquire printing resource utilization
    information for the purposes of charging Users for resources used.
 Installer  (INST) - A person or application responsible for
    installing or configuring printing system components on a local
    system.

  The purpose of these Role Models is to evaluate the relative merit of
  any given managed object.  Whenever a managed object is proposed for
  inclusion into the specification, discussion on its expected value
  should be geared around which Role Models benefit from its presence
  and operation.

Matrix of Requirement Areas and Role Models

  To better understand the relationship between the set of defined
  "Requirements Areas" and the various "Role Models," the following
  matrix is offered.

  It is important to recognize that many of the requirements areas will
  appear to be applicable to many of the Role Models.  However, when
  considering the actual context of a requirement area, it is very
  important to realize that often the actual context of a requirement



Smith, Wright, Hastings, Zilles & Gyllenskog                  [Page 109]

RFC 1759                      Printer MIB                     March 1995


  is such the Role Model can change.

  For example, it is obvious that a "System Manager" must be able to
  submit print jobs to a printer; however, when submitting a print job
  a person identified as a "System Manager" is actually operating in
  the context of a "User" in this case; hence, the requirement to
  submit a print job is not listed as a requirement for a System
  Manager.

  Conversely, while a "User" must be able to remove a job previously
  submitted to a printer, an "Operator" is often expected to be able to
  remove any print job from any printer; hence, print job removal is a
  (subtly different) requirement for both "User" and an "Operator" Role
  Models.

  That being said, I'm sure you'll find some inconsistencies in the
  following matrix, depending on your particular interpretations of the
  various requirements areas.
