1.0 INTRODUCTION
The Job Monitoring MIB [JobMIB] is intended to be implemented in a
device or server that supports any job submission protocol. 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.
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,
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:
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.
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.
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.
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.
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.
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.
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:
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.
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
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.
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.
MIB attribute | NDPS parameter | Data type

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.
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
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.
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.
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.
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.
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
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.
