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. INTERNET-DRAFT 7 J.R.

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 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 INTERNET-DRAFT 9 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 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 the 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. Figure 2 shows a block diagram of the printer and its basic 13 sub- units. Figure 2 - Printer Block Diagram INTERNET-DRAFT 10 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R.

Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. INTERNET-DRAFT 13 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 Localization is only performed on those strings in the MIB that are explicitly 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 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 INTERNET-DRAFT 14 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 associated 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 xerographic 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 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 (e.g., fuser oil) 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. INTERNET-DRAFT 15 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 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. Print Job Delivery Channels The print job delivery 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 INTERNET-DRAFT 16 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 sub-units are represented by the Print Job Delivery 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. Print Job Delivery Channel sub-units can, and usually 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 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 INTERNET-DRAFT 17 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 a critical event, initiating a trap. The exception to this rule is when the "alert alert" trap is generated. 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. 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. INTERNET-DRAFT 18 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 Available - The printer or subunit is functioning normally. Idle - The printer or subunit is not processing any print jobs Active - The printer or subunit is working on one or more print jobs Busy - The printer or subunit is "Active" and has also reached a resource threshold whereby it will not accept any new print jobs for a finite period of time. The expected next state transition from the "busy" state is to the "active" state, implying that resources are again available to accept new print jobs. The Host Resources MIB (RFC 1514) provides three status objects that can be used to describe the status of a printer: (1) hrDeviceStatus in the entry in the 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 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 Unavailable Non Critical warning(3) idle(3) or could be: lowPaper, Alert Active printing(4) lowToner, or serviceRequested Critical down(5) other(1) could be: jammed, Alert Active noPaper, noToner, coverOpen, or serviceRequested Unavailable down(5) other(1) Moving off- warning(3) idle(3) or offline line printing(4) Off-line down(5) other(1) offline Moving down(5) warmup(5) on-line Standby running(2) other(1) INTERNET-DRAFT 19 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. 2.2.13.2.1. Host MIB Printer Status For completeness, the definitions of the Printer Status objects of the Host MIB are given below: hrDeviceStatus OBJECT-TYPE SYNTAX INTEGER { unknown(1), running(2), warning(3), testing(4), down(5) } ACCESS read-only STATUS mandatory DESCRIPTION "The current operational state of the device described by this row of the table. A value unknown(1) indicates that the current state of the device is unknown. running(2) indicates that the device is up and running and that no unusual error conditions are known.

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 Unavailable because Broken 3 011'b Unknown 5 101'b Non-Critical No Non-Critical Alerts 0 Non-Critical Alerts 8 Critical No Critical Alerts 0 Critical Alerts 16 On-Line INTERNET-DRAFT 22 J.R.

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. 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 unary change events. Binary change events come in INTERNET-DRAFT 23 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 that 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 signaled 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. Removing the leading edge entry may cause the unary change event "alertRemovalofBinaryChangeEntry" to be added to the table. With binary change 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 unary 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 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. If 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 capacity 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 INTERNET-DRAFT 24 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 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 INTERNET-DRAFT 25 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. Type 1 enumerations are typically used where changes to the enumeration are either unlikely or will have a significant impact on the structure of the MIB or implementation of the MIB in management applications. Some criteria that suggest using a type 1 enumeration are: INTERNET-DRAFT 26 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 a) the set of values in the enumeration is thought to be known, e.g., faceUp and faceDown b) the enumeration defines a set of units of measure which must be understood by a management application to be able to correctly display the value of an object that measurement unit controls; and c) the enumeration is tied to the structure of the MIB or the model on which the MIB is based, e.g., the prtAlertGroup enumeration is tied to the OIDs for the related tables. 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. The current set of approved values should always be obtained from the IANA registry. Type 2 enumerations are typically used where it is important to insure consistent usage of the enumeration values; that is, to insure that the same entity does not get two different enumerations values, or two different entities do not get the same enum value. 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. The current set of approved values should always be obtained from the IANA registry. Type 3 enumerations are used for enumerations that can be extended without any controls; an example is the prtMarkerSuppliesType, which can be extended as needed by any manufacturer to describe the supplies required by a new printer. 3. Groups from other MIB Specifications This section identifies the grups from other MIBs that shall be supported to supplement and complete a printer MIB implementation. The section also describes some of the less obvious characteristics of the Printer MIB structure that are related to the inclusion of these other MIB groups and/or objects. 3.1. System Group All objects in the system group of MIB-II (RFC 1213) shall be implemented; however, as described in paragraph 3.4, implementers should carefully consider what constitutes the "system". 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 INTERNET-DRAFT 27 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 implemented.

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. 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, INTERNET-DRAFT 31 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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/. INTERNET-DRAFT 32 J.R.

All of these aspects are hidden in the channel -- abstraction. -- -- There are many kinds of print job delivery 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 services over a network connection (interface); or -- it could be a disk drive into which a floppy disk with -- the print data is inserted.

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 print job delivery channel sub-units are represented by the -- Print Job Delivery Channel Group in the Model. It has a current -- print job 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 -- Management Applications). There is also a default -- interpreter that is to be used if an interpreter is not -- explicitly specified using the Control Language. -- The print job delivery channel table and its underlying structure -- -- The first seven items in the Print Job Delivery Channel Table define the -- "channel" itself. A channel typically depends on other -- protocols and interfaces to provide the data that flows -- thru the channel. -- -- Control of a print job delivery channel is largely limited to enabling -- or disabling the entire channel itself. 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).

An application capable of using a specific PrtChannelType should be able to use the combined information from the prtChannelInformation and other channel and interface group objects to 'bootstrap' its use of the channel. prtChannelInformation is not intended to provide a general channel description, nor to provide INTERNET-DRAFT 102 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 information that is available once the channel is in use. The encoding and interpretation of the prtChannelInformation object is specific to channel type. The description of each PrtChannelType enum value for which prtChannelInformation is defined specifies the appropriate encoding and interpretation, including interaction with other objects. For channel types that do not specify a prtChannelInformation value, its value shall be null (0 length). When a new PrtChannelType enumeration value is registered, its accompanying description must specify the encoding and interpretation of the prtChannelInformation value for the channel type. prtChannelInformation semantics for an existing PrtChannelType may be added or amended in the same manner as described in section 2.4.1 for type 2 enumeration values. The prtChannelInformation specifies values for a collection of channel attributes, represented as text according to the following rules: 1. The prtChannelInformation is coded in the NVT ASCII character set. It is not affected by localization. 2. The prtChannelInformation is a list of entries representing the attribute values. Each entry consists of the following items, in order: a. a keyword, composed of alphabetic characters (A-Z, a-z), that identifies a channel attribute, b. an Equals Sign (=) to delimit the keyword, c. a data value, consisting of NVT ASCII graphics characters (codes 32-126), d. a Line Feed character (code 10) to delimit the data value. No other characters shall be present. Keywords are case-sensitive. Conventionally, keywords are capitalized (including each word of a multi-word keyword), INTERNET-DRAFT 103 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 and, since they occupy space in the prtChannelInformation, they are kept short. 3. If a channel attribute has multiple values, it is represented by multiple entries with the same keyword, each specifying one value. Otherwise, there shall be at most one entry for each attribute. 4. By default, entries may appear in any order. If there are ordering constraints for particular entries, these must be specified in their definitions. 5. The prtChannelInformation value may represent information that is not normally coded in textual form, or that is coded in a character set other than NVT ASCII. In these cases, whatever symbolic representation is conventionally used for the information should be used for encoding the prtChannelInformation. (For instance, a binary port value might be represented as a decimal number, Unicode would be represented in UTF-8 format.) 6. For each PrtChannelType for which prtChannelInformation entries are defined, the descriptive text associated with the PrtChannelType enumeration value shall specify the following information for each entry: Title: Brief description phrase, e.g.: 'Port name' 'Service Name' Keyword: The keyword value, eg: 'Port' or 'Service' Syntax: The encoding of the entry value, if it cannot be directly represented by NVT ASCII, Status: 'Mandatory', 'Optional', or 'Conditionally Mandatory' Multiplicity: 'Single' or 'Multiple' to indicate whether the entry may be present multiple times, INTERNET-DRAFT 104 J.R.

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 INTERNET-DRAFT 123 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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 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. INTERNET-DRAFT 124 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. 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. INTERNET-DRAFT 125 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. Visible state - that 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 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 prtMediaDimFeedDir and prtInputChosenMediaDimXFeedDir.

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.

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 INTERNET-DRAFT 132 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. 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. 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. INTERNET-DRAFT 133 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R. Turner, Sharp Laboratories of America Expires June 3, 1997 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. 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 INTERNET-DRAFT 134 J.R. Turner, Sharp Laboratories of America INTERNET-DRAFT J.R.
