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

Top      Up      ToC       Page 99 
   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

Top      Up      ToC       Page 100 
   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.

Top      Up      ToC       Page 101 
   Tray -- an input sub-unit which is typically removable

   Visible state -- that portion of the state of the printer that can be
   examined by a management application

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

   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.

  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

Top      Up      ToC       Page 110 
   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.

                       Role Models
