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
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
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.
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
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.
