Appendix A - Glossary of Terms

   Addressability - On the marker, the number of distinct marking units
   (pels) per unit of addressability unit that can be set; 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.

   Binary Change Event - An event which comes 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.  A binary change event may
   be critical or non-critical. See unary change event.

   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 separate ordered sets, ready for binding.

   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.

Top      Up      ToC       Page 154 
   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.

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

   Host Resources MIB - See [RFC2790].

   IANA - Internet Assigned Numbers Authority.  See [RFC3232].

   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.

   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.

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

Top      Up      ToC       Page 155 
   Media Path - The mechanisms that transport instances of the media
   from an input, through the marker, possibly through media buffers and
   duplex pathways, out to the output with optional finishing applied.
   The inputs and outputs are not part of the Media Path.

   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.

   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
   generation 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.

   Tray - An input sub-unit which is typically removable.

   Unary Change Event - An event that indicates a change of state of the
   printer, but to a state which is (often) just as valid as the state
   that was left, and from which no return is necessary.  See binary
   change event.

Top      Up      ToC       Page 156 
   Visible state - The portion of the state of the printer that can be
   examined by a management application.

   Warning - A non-critical alert.  See non-critical alert.

Appendix B - Media Size Names

   The PWG Standardized Media Names specification [PWGMEDIA], section 5
   Self  Describing Names, contains the currently recommended media size
   names.  This appendix lists the standardized media size names from
   ISO/IEC 10175 Document Printing Application (DPA), [ISO10175] as
   presented in RFC 1759.  Management applications are encouraged to use
   the names from the PWG standard.  However, many legacy systems exist
   that use the DPA names and they are presented here for the
   convenience of developers.

   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 prtInputMediaDimFeedDirChosen and
   prtInputMediaDimXFeedDirChosen.

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), [ISO10175].  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.  New names may also be created using this format
   and the names defined in the PWG Standardized Media Names
   specification [PWGMEDIA].

   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 (prtInputMediaDimFeedDirDeclared,
   prtInputMediaDimXFeedDirDeclared, 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 of any given proposed object for the MIB.
   Many times the real world need for a proposed object would be debated
   within the group; the debate would typically result in the need to
   describe the potential usage of the object in terms of a "live"
   person performing some type of printing-related task.

   Determining the value of a proposed object through identification of
   the associated human users was found to be so common that a more
   formalized model was required for consistent analysis.  The model
   describing categories of human-oriented tasks is called "Role Models"
   in this document.

   In developing the Role Models it was necessary to identify the
   common, primary tasks that humans typically face when interacting
   with a printer and its related printing system(s).  It was expected
   that certain kinds of tasks would serve to identify the various Role
   Models.

   In presenting the set of Role Models, the set of "Common Print System
   Tasks" are first presented, followed by the set of Role Model
   definitions.  Finally, a simple matrix is presented in which Role
   Models and Tasks are cross-compared.

   Common Print System Tasks

   Upon researching the many tasks encountered by humans in dealing with
   printers and printing systems, the following were found to be
   pervasive within any operating environment:

   Printer job state - Determine the status of a job without a printer.

Top      Up      ToC       Page 163 
   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 identity 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 "tasks" cover a large spectrum of requirements surrounding the
   operation of a printer in a network environment.  This list serves as
   the basis for defining the various Role Models described below.

   Proposed Role Models

   Following is the list of "Role Models" used to evaluate the
   requirements for any given Printer MIB object.  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.

Top      Up      ToC       Page 164 
   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, clearing
   simple paper jams, 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
   organization's 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 for the purpose of planning
   printer acquisitions and/or placement of printers based on usage
   trends.

   Installer  (INST) - A person or application responsible for
   installing or configuring printing system components on a local
   system.

   Accountant  (ACCT) - A person responsible for tracking the usage of
   printing resources on an ongoing basis for the purpose of charging
   Users for resources used.

   Matrix of Common Print System Tasks and Role Models

   To better understand the relationship between the set of defined
   "Common Print System Tasks" and the various "Role Models," the
   following matrix is provided.

Top      Up      ToC       Page 165 
   It is important to recognize that many of the tasks will appear to be
   applicable to many of the Role Models.  However, when considering the
   actual context of a task, it is very important to realize that often
   the actual context of a task is such that 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 the "User" and "Operator"
   Role Models.

Appendix E - Overall Printer Status Table

   The Status Table establishes a convention for the top 25 printer
   errors.  The table defines a suggested relationship between various
   printer states and the variables Printer hrDeviceStatus,
   hrPrinterStatus, hrPrinterDetectedErrorState, prtAlertGroup,
   prtAlertCode and various sub-unit status variables (prtInputStatus,
   prtOutputStatus, prtMarkerStatus, prtMediaPathStatus and
   prtChannelStatus).  This table is the recommended implementation of
   these variables.  It is provided to guide implementors of this MIB
   and users of the MIB by providing a sample set of states and the
   variable values that are expected to be produced as result of that
   state.  This information supplements that provided in Section

Top      Up      ToC       Page 166 
   2.2.13.2 "Overall Printer Status".  This is not an exhaustive list
   rather it is a guideline.

   The definition of PrtSubUnitStatusTC specifies that SubUnitStatus is
   an integer that is the sum of 5 distinct values/states: Availability,
   Critical, Non-Critical, On-line and Transitioning.  Thus when a non-
   critical alert or alerts are present the values for Availability,
   On-Line and Transitioning will be summed with the Non- Critical
   Alerts (8) value.

   The table was generated in landscape format and is located at
   ftp://ftp.pwg.org/pub/pwg/pmp/contributions/Top25Errors.pdf.
