However, the information available and the method of presentation varies significantly by job submission protocol. A common method of mapping job submission information to the Job Monitoring MIB is essential for interoperability of Job MIB agents and monitoring applications. This document defines recommended mappings for most popular job submission protocols to ensure this compatibility. Bergman Informational [Page 2]
RFC 2708 Job Submission Protocol Mapping November 1999 All mappings are unidirectional from the job submission protocol to the MIB. It is assumed that support of the job submission protocol in the printer implies that the reverse information flow is presently defined and does not require interaction from the MIB. This mapping is not defined in this document as it should be obvious. This document refers to system configurations that are defined in the Job Monitoring MIB [JobMIB]. For those readers that are familiar with the configuration descriptions, a short summary appears here. Please see the Job MIB document for further details. Configuration 1: This is a simple peer-to-peer system which contains only a client and a printer. The Job MIB agent is resident in the printer. Configuration 2: This system contains a client, server, and a printer. The Jib MIB agent is resident in the server. Configuration 3: This system, as in configuration 2, contains a client, server, and a printer. In this case the Job MIB agent is implemented within the printer. The most important object to be mapped is jmJobSubmissionID, since this is a method for the user or client to determine the jmJobIndex for a submitted job. Therefore, jmJobSubmissionID is specified for all job submission protocols defined in this document. The remaining objects mapped include only those items that have the equivalent information presented to the printer by the job submission protocol. While this document places a strong emphasis on jmJobSubmissionID mapping to obtain jmJobIndex, the preferred method is through the use of a bi-directional job submission protocol that returns the equivalent value of jmJobIndex to the client, such as IPP. When a bi-directional protocol that returns jmJobIndex is in use, the jmJobSubmissionID object has no value to the client. When the jmJobIndex cannot be returned, the use of a client defined jmJobSubmissionID is preferred over an agent derived value. The client defined version allows for retrieval of jmJobIndex using a single SNMP Get operation, since jmJobSubmissionID is the index into the jmJobIDTable. An agent derived value will require a search through multiple entries in the jmJobIDTable. The majority of the protocols mapped in this document are oriented towards network job submission. However, the Job Monitoring MIB is also intended to monitor print jobs received from other than network ports, such as parallel and serial ports. Some of the job submission protocols included that are used with non-networked ports are PJL, Bergman Informational [Page 3]
RFC 2708 Job Submission Protocol Mapping November 1999 PostScript, and TIP/SI. In addition, the Job Monitoring MIB can be used with print jobs that are internally generated, such as self test pages. In this latter case, no mapping is required since all job submission protocols are bypassed. 2.0 LINE PRINTER DAEMON (LPR/LPD) PROTOCOL The LPR/LPD printing protocol [LPD] is used with BSD UNIX systems in the client-server-printer configuration. Usage of the Job Monitoring MIB with LPR/LPD will most likely conform to Configuration 3, where the monitor application or the server uses SNMP to obtain job information from the printer. The client communicates with the UNIX server using the existing LPD protocol to obtain job information. The LPR/LPD protocol is also used in the Windows environment to implement peer-to-peer printing, as shown in configuration 1. In this case, SNMP is used by the client and/or the monitor application to obtain the job information. One of the major problems of LPR/LPD is the large number of vendor unique extensions currently used with the protocol and the resulting compatibility issues between available implementations. To avoid these issues, this mapping of LPR/LPD is restricted to the protocol as defined by RFC 1179. The LPR/LPD protocol transfers print job data and control information in separate files, known as the Data File and Control File, respectively. Most of the information concerning the print job is contained in the Control File. In many LPD implementations, the Control File is transferred following the Data File. Thus much of the information concerning the job may not be available until the completion of the data transmission. 2.1 jmJobSubmissionID Mapped to LPR/LPD The LPR/LPD Receive Data File command contains a parameter which defines the name of the data file. This name field is structured as follows: dfaXXX<host-name> or daXXXX<host-name> Where XXX or XXXX is the numeric job number assigned by the network entity submitting the print job to the printer. The recommended mapping of this name field to jmJobSubmissionID is: Bergman Informational [Page 4]
RFC 2708 Job Submission Protocol Mapping November 1999 octet 1: '9' octets 2-40: Contains the <host-name> portion of the name field. If the <host-name> portion is less than 40 octets, the left-most character in the string shall appear in octet position 2. Any unused portion of this field shall be filled with spaces. Otherwise, only the last 39 bytes shall be included. octets 41-48: '00000XXX' or '0000XXXX', where XXX or XXXX is the decimal (ASCII coded) representation of the LPR/LPD job number. 2.2 jmJobIndex Mapped to LPR/LPD The job index (jmJobIndex) is assigned by the SNMP job monitoring agent and is independent of the XXX (or XXXX) index assigned by the LPR/LPD client. This will allow the SNMP agent to track jobs received from multiple sources. 2.3 Other MIB Objects Mapped to LPR/LPD MIB Object | LPR/LPD Parameter ------------------------------+---------------------------------------- jmJobKOctetsPerCopyRequested | Number of bytes as defined in the Data | File jmJobOwner | Control file command code = P (User Id) 2.4 The Attribute Group Mapped to LPD Other attributes that are applicable, but not defined in this section such as attributes that map to a vendor unique extension, may also be included. MIB attribute | LPR/LPD information | Data type ----------------------+---------------------------------+-------------- jobName | Job Name (notes 1, 2) | Octet String queueNameRequested | Queue name from the Data File | Octet String fileName | Source File Name (notes 1, 3) | Octet String Notes: ------ 1. The information is optional in the Control File. The attribute should be included if present in the Control File. 2. Control file command code = J. If this optional field is omitted from the control file, then the agent returns the file name (command code = N), if present. 3. Control file command code = N. Bergman Informational [Page 5]
RFC 2708 Job Submission Protocol Mapping November 1999 3.0 APPLETALK PROTOCOL AppleTalk was originally developed as a peer-to-peer network protocol, as described in configuration 1, for use with Apple Macintosh computers. Today, print spoolers are also available for use with Macintosh computer networks that conform to configurations 2/3. In addition, printing with the AppleTalk protocol is supported from both Windows NT servers and Novell servers also per configurations 2/3. The AppleTalk protocol provides very little information that can be used with the Job Monitoring MIB. The Macintosh print drivers are able to provide information concerning the user and document name but imbed this information in the PDL, which is typically PostScript. The preferred jmJobSubmissionID is constructed from the information in the PostScript file, as defined in section 9.0. 3.1 jmJobSubmissionID Mapped to AppleTalk An alternative jmJobSubmissionID may be constructed from the Connection Identifier contained in the AppleTalk Printer Access Protocol (PAP) header. Since the Connection Id is not readily available in any of the defined AppleTalk implementations, this approach may be of little utility. octet 1: 'A' octets 2-40: Contains the AppleTalk printer name, with the first character of the name in octet 2. AppleTalk printer names are a maximum of 31 characters. Any unused portion of this field shall be filled with spaces. octets 41-48: '00000XXX', where 'XXX' is the decimal (ASCII coded) representation of the Connection Id. 3.2 Other AppleTalk Mappings No other Job MIB objects or parameters can be derived from information available in the AppleTalk headers 4.0 INTERNET PRINTING PROTOCOL (IPP) The Internet Printing Protocol [IPP] supports printing using any one of the three possible configurations. For configuration 2, the mapping defined herein is performed on an agent within the server. Otherwise, the mapping is performed on an agent within the printer. Bergman Informational [Page 6]
RFC 2708 Job Submission Protocol Mapping November 1999 4.1 jmJobSubmissionID Mapped to IPP IPP contains a rich set of parameters which allow several methods of creating the jmJobSubmissionID object. To prevent interoperability problems, the preferred method is to use the IPP job-uri attribute as follows: octet 1: '4' octets 2-40: Contains the IPP job-uri job description attribute generated by the printer. (The job-uri is returned to the client by IPP.) If the job-uri is less than 40 octets, the left-most character in the string shall appear in octet position 2. Any unused portion of this field shall be filled with spaces. Otherwise, only the last 39 bytes shall be included. octets 41-48: Contains the decimal (ASCII coded) representation of the job-id job description attribute. Leading zeros shall be inserted to fill the entire 8 octet field. NOTE - Since IPP returns the "job-identifier" attribute with the jmJobIndex value for a job when the job is submitted, the use of the jmJobSubmissionID table should not be needed by a management application. See Section 1.0. 4.2 jmJobIndex Mapped to IPP The job index (jmJobIndex) assigned by the SNMP job monitoring agent is returned to the client by IPP as the job-id job description attribute. (Since IPP does not require consecutively generated job- ids, the agent may receive jobs from multiple clients and can assign jmJobIndex in an ascending sequence independent of the submitting job client.) The IPP job-id must be restricted to the range of 1 to 99,999,999 (decimal) to allow the value to be properly represented in jmJobSubmissionID. Bergman Informational [Page 7]
RFC 2708 Job Submission Protocol Mapping November 1999 4.3 Other MIB Objects Mapped to IPP MIB Object | IPP Job attribute ---------------------------------+----------------------------------- jmJobState | job-state jmJobStateReasons1 | job-state-reasons (note 1) jmNumberOfInterveningJobs | number-of-intervening-jobs jmJobKOctetsPerCopyRequested | job-k-octets jmJobKOctetsProcessed | job-k-octets-processed jmJobImpressionsPerCopyRequested | job-impressions jmJobImpressionsCompleted | job-impressions-completed jmJobOwner | job-originating-user-name Notes: ------ 1. jmJobStateReasons1 is a bit map which can describe up to 31 job state reasons. Also the IPP "job-state-reasons" attribute is a multi-valued attribute with each value being a keyword. The IPP condition may change multiple bits in this object. The IPP "job- state-reasons" attribute may also change one or more of the jobStateReasonsN attributes (see section 4.4). 4.4 The Attribute Group Mapped to IPP The following mappings are required if the listed IPP job template attribute is provided. Bergman Informational [Page 8]
RFC 2708 Job Submission Protocol Mapping November 1999 MIB attribute | IPP job attribute | Data type ---------------------------+------------------------------+------------- jobStateReasonsN(N=2, 3, 4)| job-state-reasons (note 3) | Integer jobCodedCharSet | attributes-charset (note 1) | Octet String jobNaturalLanguageTag | attributes-natural-language | Octet String jobURI | job-uri | Octet String jobName | job-name | Octet String physicalDevice | output-device-assigned | Octet String numberOfDocuments | number-of-documents | Integer jobPriority | job-priority | Integer jobHoldUntil | job-hold-until | Octet String sides | sides (note 2) | Integer finishing | finishings | Integer printQualityRequested | print-quality | Integer printerResolutionRequested | printer-resolution | Integer jobCopiesRequested | copies (note 4) | Integer documentCopiesRequested | copies (note 4) | Integer jobCollationType | multiple-document-handling | Integer sheetsRequested | job-media-sheets | Integer sheetsCompleted | job-media-sheets-completed | Integer mediumRequested | media | Octet String jobSubmissionTime | time-at-submission | Integer jobStartedProcessingTime | time-at-processing | Integer jobCompletionTime | time-at-completed | Integer Notes: ------ 1. jobCodedCharSet is an enum from the IANA registry which is also used in the Printer MIB. The IPP attributes-charset is the name (MIME preferred name) of the character set. 2. The Job MIB sides attribute uses the integer values "1" and "2". The IPP sides attribute uses three keywords. 3. jobStateReasonsN are three attributes (N=2, 3, 4). Also the IPP "job-state-reasons" attribute is a multi-valued attribute with each value being a keyword. The IPP condition may change multiple bits in one or more of these Job MIB attributes. See also jmJobStateReasons1 in section 4.3. 4. The IPP "copies" attribute maps to the Job MIB: (1) jobCopiesRequested when the job has only one document OR IPP "multiple-document-handling" is 'single-valued' (2) documentCopiesRequested, in which case the MIB value is the total number of document copies that the job will produce as a whole. Bergman Informational [Page 9]
RFC 2708 Job Submission Protocol Mapping November 1999 5.0 INTELLIGENT PRINTER DATA STREAM (IPDS) The IPDS datastream facilitates a close relationship between the print supervisor (Print Services Facility - PSF) and the printer. There are PSF applications for UNIX, Windows, OS/2, OS/400 and host operating systems such as VM, MVS and VSE. Together, PSF and IPDS represent a complete, mature and robust job management framework which includes font and resource management, page progress tracking, job cancellation, complete error recovery and end-user notification. Because PSF and the printer correspond via the use of locally assigned IDĘs, there is a limited amount of clear text information provided during submission for use by the Job MIB. 5.1 jmJobSubmissionId Mapped to IPDS For IPDS on the MVS or VSE platform: octet 1: 'E' octets 2-40: Contains bytes 2-27 of the XOH Define Group Boundary Group ID triplet. Octet position 2 must carry the value x'01'. Bytes 28-40 must be filled with spaces. octets 41-48: Contains a decimal (ASCII coded) representation of the jmJobIndex assigned by the agent. Leading zeros shall be inserted to fill the entire 8 octet field. For IPDS on the VM platform: octet 1: 'F' octets 2-40: Contains bytes 2-31 of the XOH Define Group Boundary Group ID triplet. Octet position 2 must carry the value x'02'. Bytes 32-40 must be filled with spaces. octets 41-48: Contains a decimal (ASCII coded) representation of the jmJobIndex assigned by the agent. Leading zeros shall be inserted to fill the entire 8 octet field. For IPDS on the OS/400 platform: octet 1: 'G' octets 2-40: Contains bytes 2-36 of the XOH Define Group Boundary Group ID triplet. Octet position 2 must carry the value x'03'. Bytes 37-40 must be filled with spaces. Bergman Informational [Page 10]
RFC 2708 Job Submission Protocol Mapping November 1999 octets 41-48: Contains a decimal (ASCII coded) representation of the jmJobIndex assigned by the agent. Leading zeros shall be inserted to fill the entire 8 octet field. 5.2 The Attribute Group Mapped to IPDS For MVS/VSE: MIB attribute | IPDS XOH DGB Group ID | Data type ----------------------------------+-----------------------+------------- jobSourcePlatformType sptMVS(7) | Byte 2 = x'01' | Integer jobName | Bytes 4-11 | Octet String For VM: MIB attribute | IPDS XOH DGB Group ID | Data type ----------------------------------+-----------------------+------------- jobSourcePlatformType sptVM(8) | Byte 2 = x'02' | Integer fileName | Bytes 4-11 | Octet String For OS/400: MIB attribute | IPDS XOH DGB Group ID | Data type ----------------------------------+-----------------------+------------- jobSourcePlatformType sptOS400(9) | byte 2 = x'03' | Integer fileName | Bytes 23-32 | Octet String jobName | Bytes 37-46 | Octet String 6.0 DOCUMENT PRINTING APPLICATION (DPA) The ISO 10175 Document Printing Application (DPA) [DPA] supports printing using any one of the three possible configurations. For configuration 2, the mapping defined herein is performed on a server. Otherwise, the mapping is performed on an agent within the printer. 6.1 jmJobSubmissionID Mapped to DPA DPA contains a rich set of parameters which allow several methods of creating the jmJobSubmissionID object. To prevent interoperability problems, the preferred method is to use the DPA job-owner attribute as follows: Bergman Informational [Page 11]
RFC 2708 Job Submission Protocol Mapping November 1999 octet 1: '0' octets 2-40: Contains the DPA job-owner attribute supplied by the submitter. If the job-owner is less than 40 octets, the left-most character in the string shall appear in octet position 2. Any unused portion of this field shall be filled with spaces. Otherwise, only the last 39 bytes shall be included. octets 41-48: Contains an 8-digit sequential decimal number. 6.2 jmJobIndex Mapped to DPA The job index (jmJobIndex) assigned by the SNMP job monitoring agent is returned to the client by DPA as a decimal digit string as the value of the DPA job-identifier attribute. (Since DPA does not require consecutively generated job-identifiers, the agent may receive jobs from multiple clients and can assign the jmJobIndex in an ascending sequence independent of the submitting job client.) The DPA job-identifier must be restricted to the range of 1 to 99,999,999 (decimal) to allow the value to be properly represented in jmJobSubmissionID. NOTE - Since DPA returns the "job-identifier" attribute with the jmJobIndex value for a job when the job is submitted, the use of the jmJobSubmissionID table should not be needed by a management application. See Section 1.0. 6.3 Other MIB Objects Mapped to DPA MIB Object | DPA Job attribute ---------------------------------+------------------------------------ jmJobState | job-state jmJobStateReasons1 | job-state-reasons (note 2) jmNumberOfInterveningJobs | intervening-jobs jmJobKOctetsPerCopyRequested | total-job-octets (notes 1, 3) jmJobKOctetsProcessed | job-octets-completed (note 1) jmJobImpressionsPerCopyRequested | job-impression-count (note 3) jmJobImpressionsCompleted | impressions-completed jmJobOwner | job-owner Notes: ------ 1. jmJobKOctetsPerCopyRequested and jmJobKOctetsProcessed is in K octets while the DPA job-total-octets and job-octets-completed is in octets and is 63-bits of significance. Bergman Informational [Page 12]
RFC 2708 Job Submission Protocol Mapping November 1999 2. jmJobStateReasons1 is a bit map which can describe up to 31 job state reasons. Also the DPA "job-state-reasons" attribute is a multi-valued attribute with each value being an object identifier (OID). The DPA condition may change multiple bits in this object. The DPA condition may also change one or more of the jobStateReasonsN attributes (see section 4.4) 3. DPA octets include the multiplication factor due to job and document copies, while the MIB values do not. 6.4 The Attribute Group Mapped to DPA The following mappings are required if the listed DPA job attribute is provided. MIB attribute | DPA job attribute |IPP Data type ---------------------------+------------------------------+------------- jobStateReasonsN(N=2, 3, 4)| job-state-reasons (note 2) | Integer jobCodedCharSet | (note 1) | Octet String jobAccountName | accounting-information | Octet String jobName | job-name | Octet String deviceNameRequested | printer-name-requested | Octet String physicalDevice | printers-assigned | Octet String numberOfDocuments | number-of-documents | Integer fileName | file-name | Octet String documentName | document-name | Octet String jobComment | job-comment | Octet String documentFormat | document-format | Octet String jobPriority | job-priority | Integer jobProcessAfterDateAndTime | job-print-after | Octet String outputBin | results-profile.output-bin | Octet String sides | sides (note 3) | Integer finishing | job-finishing, finishing | Integer printQualityRequested | print-quality | Integer printerResolutionRequested | default-printer-resolution | Integer | (note 4) | jobCopiesRequested | results-profile.job-copies | Integer jobCopiesCompleted | job-copies-completed | Integer documentCopiesRequested | copy-count (note 5) | Integer documentCopiesCompleted | copies-completed (note 6) | Integer sheetsRequested | job-media-sheet-count | Integer sheetsCompleted | job-media-sheets-completed | Integer pagesRequested | job-page-count | Integer pagesCompleted | pages-completed | Integer mediumRequested | page-media-select, | Octet String | default-medium | jobSubmissionTime | submission-time (note 7) | Octet String jobStartedProcessingTime | started-printing-time (note 7) Octet String jobCompletionTime | completion-time (note 7) | Octet String Bergman Informational [Page 13]
RFC 2708 Job Submission Protocol Mapping November 1999 Notes: ------ 1. Every DPA attribute is tagged indicating the coded character set to be used for that attribute. 2. jobStateReasonsN are three attributes (N=2, 3, 4). The DPA condition may change one or more of the bits in one or more of these Job MIB items. Also the DPA job-state-reasons is a multi- valued attribute with each value being an OBJECT IDENTIFIER (OID). 3. The Job MIB sides attribute is an integer '1' or '2' while the DPA sides attribute has one of six OID values that includes plex. 4. printerResolutionRequested has x and y resolution and is intended to override the resolution instruction in the document, if any, while the DPA default-printer-resolution is the same in x and y and only takes effect if the document does not contain a resolution instruction 5. The DPA "copy-count" attribute is a per-document attribute, so the MIB value is the sum of the documents' "copy-count" values times the job's "results-profile.job-copies" value. 6. The DPA "copies-completed" attribute is a per-document attribute, so the MIB value is the sum of the documents' "copies-completed" values times the job's "results-profile.job-copies" value. 7. The DPA GeneratlizedTime data type is defined by ISO 8824 (ISO- 8824) while the MIB DateAndTime is defined by SNMPv2-TC (SNMPv2- TC). 7.0 NOVELL DISTRIBUTED PRINT SERVICE (NDPS) Novell Distributed Print Services is a DPA based job submission protocol that conforms to configuration 3. 7.1 jmJobSubmissionID Mapped to NDPS NDPS supports the generation of a properly formatted jmJobSubmissionID for use in the Job MIB, via the attribute ndps- att-job-identifier. 7.2 jmJobIndex Mapped to NDPS NDPS defines the attribute ndps-att-job-identifier-on-printer that can be used to return the value of jmJobIndex to the NDPS client. See Section 1.0. Bergman Informational [Page 14]
RFC 2708 Job Submission Protocol Mapping November 1999 7.3 Other MIB Objects Mapped to NDPS MIB Object | NDPS Parameter ---------------------------------+-------------------------------------- jmJobState | ndps-att-current-job-state (note 1) jmJobStateReasons1 | ndps-att-job-state-reasons (note 2) jmNumberOfInterveningJobs | ndps-att-intervening-jobs jmJobKOctetsPerCopyRequested | ndps-att-total-job-octets (notes 3,4) jmJobKOctetsProcessed | ndps-att-octets-completed (note 3) jmJobImpressionsPerCopyRequested | ndps-att-job-impressions-count jmJobImpressionsCompleted | ndps-att-impressions-completed jmJobOwner | ndps-att-job-owner (note 5) Notes: ------ 1. Some of the NDPS job states must be represented by both a jmJobState and a jmJobStateReasons1 object or a jobStateReasonsN attribute (N=2, 3, 4). 2. The NDPS job state reasons may be mapped to either the object jmJobStateReasons1 or the attribute jobStateReasonsN (N=2, 3, 4). 3. jmJobKOctetsPerCopyRequested and jmJobKOctetsProcessed is in K octets while the NDPS ndps-att-job-total-octets and ndps-att-job- octets-completed is in octets and is 63-bits of significance. 4. NDPS octets include the multiplication factor due to job and document copies, while the MIB values do not. 5. The Job MIB object must be multiplied by the attribute jobCopiesRequested to obtain the NDPS attribute value, if multiple copies have been requested. 7.4 The Attribute Group Mapped to NDPS The following mappings are required if the listed PJL attribute or command option is provided. Bergman Informational [Page 15]
RFC 2708 Job Submission Protocol Mapping November 1999 MIB attribute | NDPS parameter | Data type ---------------------------+------------------------------+------------- jobStateReasonsN(N=2, 3, 4)| ndps-job-state-reasons | Integer jobAccountName | ndps-att-job-owner | Octet String jobName | ndps-att-job-name | Octet String jobOriginatingHost | ndps-att-job-originator | Octet String deviceNameRequested | ndps-att-printer-name-- | Octet String | requested | numberOfDocuments | ndps-att-number-of-documents | Integer fileName | ndps-att-document-file-name | Octet String documentName | ndps-att-document-name | Octet String jobComment | ndps-att-job-comment | Octet String documentFormatIndex | ndps-att-prtInterpreterIndex | Integer documentFormat | ndps-att-document-format | Integer jobPriority | ndps-att-job-priority | Integer jobProcessAfterDateAndTime | ndps-att-job-print-after | Octet String outputBin | ndps-att-results-profile | Integer | (note 1) | sides | ndps-att-sides (note 2) | Integer finishing | ndps-att-job-finishing | Integer printQualityRequested | ndps-att-print-quality | Integer printerResolutionRequested | ndps-att-default-printer-- | | resolution (note 3) | Integer printerResolutionUsed | ndps-att-default-resolutions-- | used | Integer jobCopiesRequested | ndps-att-results-profile | Integer | (note 4) | jobCopiesCompleted | ndps-att-job-copies-completed| Integer documentCopiesRequested | ndps-att-copy-count (note 5) | Integer documentCopiesCompleted | ndps-att-copies-completed | Integer | (note 6) | sheetsRequested | ndps-att-job-media-- | | sheet-count | Integer sheetsCompleted | ndps-att-media-sheets-- | | completed | Integer mediumConsumed | ndps-att-media-used | Integer jobSubmissionToServerTime | ndps-att-submission-time | Octet String | (note 7) | jobSubmissionTime | ndps-att-started-printing-time Octet String | (note 7) | jobCompletionTime | ndps-att-completion-time | Octet String | (note 7) | Notes: ------ 1. The output-bin field in ndps-att-results-profile is to be used. 2. The Job MIB sides attribute is an integer '1' or '2' while the NDPS sides attribute has one of six OID values that includes plex. Bergman Informational [Page 16]
RFC 2708 Job Submission Protocol Mapping November 1999 3. printerResolutionRequested has x and y resolution and is intended to override the resolution instruction in the document, if any, while the ndps-att-default-printer-resolution is the same in x and y and only takes effect if the document does not contain a resolution instruction 4. The job-copies field in ndps-att-results-profile is to be used. 5. The NDPS "copy-count" attribute is a per-document attribute, so the MIB value is the sum of the documents' "copy-count" values times the job's "results-profile.job-copies" value. 6. The NDPS "copies-completed" attribute is a per-document attribute, so the MIB value is the sum of the documents' "copies-completed" values times the job's "results-profile.job-copies" value. 7. The NDPS GeneratlizedTime data type is defined by ISO 8824 (ISO- 8824) while the MIB DateAndTime is defined by SNMPv2-TC (SNMPv2- TC). 8.0 PRINTER JOB LANGUAGE (PJL) PJL [PJL] has been developed by Hewlett-Packard to provide job control information to the printer and status information to applications, independent of the PDL. 8.1 jmJobSubmissionID Mapped to PJL PJL has defined the SUBMISSIONID option for the JOB command which indicates a properly formatted jmJobSubmissionID for use in the Job MIB. The PJL JOB command is presented at the start of a print job with options that apply only the attached job. The syntax for this command option is: @PJL JOB SUBMISSIONID = "id string" Driver software that implements this PJL command option must provide the "id string" in one of the client version formats specified in the Job MIB for jmJobSubmissionID. For drivers that are not able to create the SUBMISSIONID option, it is recommended that jmJobSubmissionID format 0 be created by the agent using the PJL attribute DocOwner or DocOwnerId. octet 1: '0' octets 2-40: Contains the string associated with DocOwner or DocOwnerId. If the string is less than 40 octets, the left-most character in the string shall appear in octet Bergman Informational [Page 17]
RFC 2708 Job Submission Protocol Mapping November 1999 position 2. Otherwise, only the last 39 bytes shall be included. Any unused portion of this field shall be filled with spaces. If DocOwner or DocOwnerId cannot be obtained, this field shall be blank. octets 41-48: Contains the value of jmJobIndex associated with the job. Leading zeros shall be inserted to fill the entire 8 octet field. 8.2 jmJobIndex Mapped to PJL PJL does not provide a value that can be mapped to jmJobIndex. 8.3 Other MIB Objects Mapped to PJL MIB Object | PJL Job attribute ----------------------+------------------------------------ jobOwner | DocOwner or DocOwnerId attribute 8.4 The Attribute Group Mapped to PJL The following mappings are required if the listed PJL attribute or command option is provided. MIB attribute | PJL attribute or command option | Data type ----------------------+----------------------------------+-------------- serverAssignedJobName | DocName attribute or the command | Octet String | @PJL JOB Name = "string" | Octet String submittingServerName | SrcServerName attribute | Octet String jobOriginatingHost | SrcPort attribute | Octet String queueNameRequested | SrcQ attribute | Octet String fileName | JobFName attribute | Octet String jobComment | JobDesc attribute | Octet String jobSubmissionTime | TimeSubmit attribute | Octet String 9.0 POSTSCRIPT The PostScript PDL permits comment fields which can be used by application drivers to include job information. Although there are no restrictions or requirements as to what information may be included, many drivers include job owner and/or document name. Bergman Informational [Page 18]
RFC 2708 Job Submission Protocol Mapping November 1999 9.1 jmJobSubmissionID Mapped to PostScript The use of a standard format job submission id comment string will allow interoperability of printers and drivers from multiple vendors. The following comment string format is recommended for use with PostScript level 1 and level 2 data streams. %%JMPJobSubmissionId:(id-string) where "id string" can be any jmJobSubmissionID format reserved for clients. 9.2 Other MIB Objects and Attributes Mapped to PostScript No Other mappings from PostScript comment strings are recommended, but many Job MIB objects and attributes can be defined using vendor unique comment strings. 10.0 NETWARE PSERVER The NetWare PServer job submission protocol is implemented in a client- server-printer system on the server to printer link as defined in configuration 3. 10.1 jmJobSubmissionID Mapped to PServer octet 1: 'B' octets 2-40: Contains the Directory Path Name of the agent as recorded by the Novell File Server in the queue directory. If the string is less than 40 octets, the left-most character in the string shall appear in octet position 2. Otherwise, only the last 39 bytes shall be included. Any unused portion of this field shall be filled with spaces. octets 41-48: '000XXXXX' The decimal (ASCII coded) representation of the Job Number as per the NetWare File Server Queue Management Services. 10.2 jmJobIndex Mapped to PServer The job index (jmJobIndex) is assigned by the SNMP job monitoring agent and is independent of the Job Number assigned by the NetWare File Server Queue Management Services. This will allow the SNMP agent to track jobs received from multiple sources. Bergman Informational [Page 19]
RFC 2708 Job Submission Protocol Mapping November 1999 10.3 Other MIB Objects Mapped to PJL MIB Object | PServer Job attribute ----------------------+-------------------------------------------- jobOwner | Client Id Number 10.4 The Attribute Group Mapped to PServer The following mappings are required if the listed PServer parameter is provided in the Novell File Server queue directory. MIB attribute | PServer parameter | Data type ---------------------------+-----------------------------+-------------- serverAssignedJobName | Job File Name | Octet String queueNameRequested | Queue Id | Integer physicalDevice | Server Id Number | Integer jobComment | Job Description | Octet String jobPriority | (note 1) | Integer jobProcessAfterDateAndTime | Target Execution Time | Octet String jobCopiesRequested | Number of Copies | Integer mediumRequested | Form Name | Octet String jobSubmissionToServerTime | Job Entry Time | Octet String Notes: ------ 1. The job priority is determined by the priority assigned to the queue that contains the job. Each queue can be assigned a unique priority and the priority of the job is inherited from the queue. 11.0 NETWARE NPRINTER or RPRINTER The NetWare NPrinter/RPrinter protocol was designed to transfer print data from a Novell File Server to a printer attached directly to a local port (e.g. parallel or serial) on a PC. NPrinter/RPrinter is an extremely lightweight printing protocol. Consequently, no information required by the Job Monitoring MIB is provided and a meaningful jmJobSubmissionID cannot be generated. It is recommended that an additional job submission layer, such as PJL or another vendor private protocol, be included on top of NPrinter/RPrinter to provide the required information. The mapping should then be performed according to the recommendations of the higher layer submission protocol. Bergman Informational [Page 20]
RFC 2708 Job Submission Protocol Mapping November 1999 12.0 SERVER MESSAGE BLOCK (SMB) PROTOCOL The Server Message Block protocol is used with several PC Network operating systems, such as Microsoft Windows for Workgroups, IBM LAN Server, and Artisoft Lantastic. SMB systems supporting the Job Monitoring MIB will conform to either configuration 1 or 3. 12.1 jmJobSubmissionID Mapped to SMB octet 1: 'C' octets 2-40: Contains a decimal (ASCII coded) representation of the 16 bit SMB Tree Id field, which uniquely identifies the connection that submitted the job to the printer. The most significant digit of the numeric string shall be placed in octet position 2. All unused portions of this field shall be filled with spaces. The SMB Tree Id has a maximum value of 65,535. octets 41-48: Contains a decimal (ASCII coded) representation of the File Handle returned from the printer agent to the client in response to a Create Print File command. Leading zeros shall be inserted to fill the entire 8 octet field. 12.2 jmJobIndex Mapped to SMB It is strongly recommended that the File Handle returned from the printer agent be identical to jmJobIndex. If these items are identical, there is no need for the client application to perform a search on jmJobSubmissionID. To be compatible with the 16 bit field allocated to this value by SMB, the maximum jmJobIndex is 65,535. 12.3 Other MIB objects Mapped to SMB MIB Object | SMB Parameter ----------------+------------------------------------------------ jmJobOwner | SMB User Id field (note 1) Notes: ------ 1. A decimal (ASCII coded) representation of the SMB User Id numeric shall be presented as jmJobOwner. Bergman Informational [Page 21]
RFC 2708 Job Submission Protocol Mapping November 1999 13.0 TRANSPORT INDEPENDENT PRINTER/SYSTEM INTERFACE (TIP/SI) The TIP/SI protocol, although currently specified as a part of the IEEE 1284 parallel port standards [TIP/SI], was originally developed as a network protocol. TIP/SI thus has the potential of being integrated into any network or non-network configuration. 13.1 jmJobSubmissionID Mapped to TIP/SI octet 1: 'D' octets 2-40: Contains the Job Name from the Job Control-Start Job (JC-SJ) command. If the Job Name portion is less than 40 octets, the left-most character in the string shall appear in octet position 2. Any unused portion of this field shall be filled with spaces. Otherwise, only the last 39 bytes shall be included. octets 41-48: Contains a decimal (ASCII coded) representation of the jmJobIndex assigned by the agent. Leading zeros shall be inserted to fill the entire 8 octet field. 13.2 jmJobIndex Mapped to TIP/SI jmJobIndex is returned to the client as the Printer Assigned Job Id in a Job Control-Start Job (JC-SJ) response packet. To be compatible with the 16 bit field allocated to this value by TIP/SI, the maximum jmJobIndex is 65,535. 13.3 Other MIB Objects Mapped to TIP/SI MIB Object | TIP/SI Parameter -----------------------+--------------------------------------------- jmJobOwner | User string 13.4 The Attribute Group Mapped to TIP/SI MIB attribute | TIP/SI information | Data type ----------------------+---------------------------------+------------- jobName | Job Name string | Octet String jobComment | Additional Information string | Octet String Bergman Informational [Page 22]
RFC 2708 Job Submission Protocol Mapping November 1999 14.0 Security Considerations This document provides mapping recommendations of job submission protocols for use with the Job Monitoring MIB. The mapping procedures defined do not enhance or compromise any security provisions available within the job submission protocols contained within this document. The security considerations specified for the Job Monitoring MIB [JobMIB] are also unaffected by any of the recommendations in this document. The security provisions available in the job submission protocols are documented in the appropriate specifications that define the protocols. The degree of security available varies from very good, for protocols such as the Internet Printing Protocol [IPP], to non- existent, for example the Line Printer Daemon Protocol [LPD]. Since the defined mapping operation occurs as a secondary operation after the user has been authenticated and there is no storage of any authorization credentials other than the user name, no security breaches are anticipated. Also, the Job MIB does not provide any back-door mechanism for access to any other security parameters. However, implementers must always consider the impact of the defined mapping procedures upon the security model desired from the protocol. 15.0 REFERENCES [DPA] ISO/IEC 10175-1:1996(E), "Information technology - Text and office systems - Document Printing Application (DPA) - Part 1: Abstract service definition and procedures", JTC1/SC18.
