x-side1-image-shift (integer (MIN:MAX))
This attribute causes the page images, on the front of each sheet, to be shifted in position with respect to the media on which the page images are to be rendered. The direction MUST be along the x-axis of the Coordinate System (see section ). The sign of the value indicates the direction of the shift.
If the bind edge is along the y-axis, then a bind edge image shift can be accomplished by applying image shifts of equal magnitude, and opposite sign, to the "x-side1-image-shift" and "x-side2-image-shift" attributes, respectively.
If the client supplies the "x-image-auto-center" or "x-image-shift" attributes, then the Printer MUST apply the "x-image-auto-center" attribute first, followed by the "x-image-shift" attribute, and finally the "x-side1-image-shift" and "x-side2-image-shift" attributes.
The unit of measure for this attribute is hundredths of a millimeter. This is equivalent to 1/2540th of an inch resolution.
x-side2-image-shift (integer (MIN:MAX))
This attribute causes the page images, on the back of each sheet, to be shifted in position with respect to the media on which the page images are to be rendered. The direction of shift MUST be along the x-axis of the Coordinate System (see section ). The sign of the value indicates the direction of the shift.

The unit of measure for this attribute is hundredths of a millimeter. This is equivalent to 1/2540th of an inch resolution.
y-image-auto-center (boolean)
This attribute causes the page images to be centered along the y-axis on the media to which they are applied.
If the client supplies the "y-image-image," "y-side1-image-shift" or "y-side2-image-shift" attributes, then the Printer MUST apply the "y-image-auto-center" attribute first, followed by the "y-image-shift" attribute, and finally the "y-side1-image-shift" and "y-side2-image-shift" attributes.
y-image-shift (integer (MIN:MAX))
This attribute causes the page images on both sides of each sheet, to be shifted in position with respect to the media on which the page images are to be rendered. The direction of shift MUST be along the y-axis of the Coordinate System (see section ). The sign of the value indicates the direction of the shift.
If the client supplies the "y-image-auto-center," "y-side1-image-shift" or "y-side2-image-shift" attributes, then the Printer MUST apply the "y-image-auto-center" attribute first, followed by the "y-image-shift" attribute, and finally the "y-side1-image-shift" and "y-side2-image-shift" attributes.

Job Description Attributes
This section defines Job Description attributes for use with IPP/1.0 [RFC 2566] and IPP/1.1 [ipp-mod].
current-page-order (type2 keyword)
This attribute represents the current page order of the document data supplied with the job. Initially "current-page-order" is set to the value of the Job Template attribute "page-order-received." The value of "current-page-order" may change based on processing and the value of the "page-order-delivery" attribute. If the Printer changes the value of a Job's "current-page-order" Job Description attribute, then it is assumed that the associated document data has been transformed in some way to reflect this change. It should be noted that the document data that "current-page-order" refers to is not always the document data sent with the create request, but may also refer to the processed images that are to be delivered to the printer. The standard values for this attribute are the same as for of the "page-order-received" attribute (see section ), namely '1-to-n-order' and 'n-to-1-order'.
Out of Band Values
This section defines out-of-band values (see [ipp-mod] section 4.1) for use with attributes defined in this and other documents.
'none'
This "out-of-band" value allows a client, in a request, to specify that the value of a Job Template attribute MUST be semantically equivalent to 'none.' This out-of-band value is needed since attributes that are of the 'collection', 'name' or 'text' syntax can be problematic when a client wishes to specify that an xxx-default attribute MUST NOT be applied to the job. Unlike the 'keyword' syntax, where the value of 'none' (or its equivalent) can be a standard value, other attribute syntaxes have no such mechanism.
A Printer MUST support the use of the "out-of-band" value for any attribute that calls for its use, such as any Job Template attribute that has the 'collection' attribute syntax, if the Printer supports the use of the 'collection' attribute syntax for that attribute.
When a client sends a request to the printer object, the "out-of-band" value 'none' MUST only be used for Job Template attributes whose definitions explicitly indicate that the use of "out-of-band" value 'none' is allowed. A client MUST NOT use the "out-of-band" 'none' value for attributes whose definition does not explicitly call out its use.
'none'
|
The specified Job Template attribute in the request MUST NOT be applied to the job. Specifically, this value overrides the Printer's "xxx-default" attribute value for the Job Template attribute, if one exists.
|
ISSUE 04 - Should we move the definition of the 'none' out-of-band value to the 'collection' specification (ipp-coll), since that document is IETF standards track, while this one is PWG?
At the New Orleans meeting, we agreed to move the out-of-band 'none' to the 'collection' document.
Conformance Requirements
This section summarizes the Conformance Requirements detailed in the definitions in this document. In general each of the attributes defined in this document are OPTIONAL for a Printer to support, so that Printer implementers MAY implement any combination of attributes. Only the following conditional conformance requirements are defined:
If the Printer supports:
|
then the Printer MUST also support (but vice-versa is OPTIONAL):
|
"cover-back"
|
"cover-front"
|
"x-side2-image-shift"
|
"x-side1-image-shift"
|
"y-side2-image-shift"
|
"y-side1-image-shift"
|
"x-side1-image-shift"
|
"x-image-shift"
|
"y-side1-image-shift"
|
"y-image-shift"
|
Each of the collection attribute definitions indicate which member attributes are REQUIRED and which are OPTIONAL for a Printer to support.
If a Printer supports the 'collection' attribute syntax of a Job Template attribute that has 'type3 keyword | name(MAX) | collection' attribute syntax, then it MUST also support some values of the standard 'keyword' attribute syntax defined for that attribute. Support of the 'name' attribute syntax for such Job Template attributes is OPTIONAL, as in IPP/1.1.
If a Printer supports the 'collection' attribute syntax of a Job Template attribute, then it MUST support the "out-of-band" 'none' value (see section ) in a client Job Creation and Document Creation request.
IANA Considerations
IANA will be called on to register the attributes defined in this document, using the procedures outlined in [ipp-mod].
Internationalization Considerations
The IPP extensions defined in this document require the same internationalization considerations as any of the Job Template attributes defined in IPP/1.1 [ipp-mod].
Security Considerations
The IPP extensions defined in this document require the same security considerations as any of the Job Template attributes defined in IPP/1.1 [ipp-mod].

Appendix A: Change History
This section summarizes the changes to the document. Each sub-section is in reverse chronological order. Adding or removing ISSUES that don't change the document are not listed here.
Changes to the January 30, 2000 to create the February 7, 2000 version
The following changes were made to the January 30, 2000 version to create the February 7, 2000 version:
Changed the attribute syntax of "cover-front-supported" and "cover-back-supported" from 'collection' to 'boolean', since a Printer MUST support all (both) member attributes and any combinations of values.
Changed the 'sheet' member attribute in each of the following collections to give them distinct names so that the "xxx-supported" Printer attribute can indicate their respective (potentially different) values: "job-accounting-sheets", "job-error-sheets", "job-sheets", and "separator-sheets".
Added "media-" to the beginning of each member attribute of the "media" collection, so that ordinary "media-xxx-supported" could be used to represent their individual supported values.
Removed the 'name(MAX)" choice from the "media-size" member attribute. If the properties of a medium are being given, either the keyword name or the exact numerical dimensions known to the implementation, not a name made up by the administrator.
Added "media-size-supported (1setOf collection) which contains the combinations of numerical sizes supported (x-dimension and y-dimension) by the Printer. This "xxx-supported" attribute is the only one that has a value of '1setOf collection' in order to list the pairs of x and y dimensions supported. The attribute syntax of the "x-dimension" and "y-dimension" is a choice of 'integer(0:MAX)' or 'rangeOfInteger(0:MAX)' to cover the case of continuous media and cut sheet printers that can cut the medium to any size within the specified range.
Changed the "media-supported" from containing a collection whose member attributes listed the supported values that the client could supply as member attributes to just containing a new out-of-band 'any-collection' value that indicates that the implementation allows any combination of member attributes that are indicated by the corresponding "xxx-supported" Printer attributes.
Changes to the January 28, 2000 to create the January 30, 2000 version
The following changes were made to the January 28, 2000 version to create the January 30, 2000 version:
Ordered the Job Template attributes alphabetically.
Add 'name(MAX)' to Job Template attributes that had (type3 keyword | collection) to be consistent with IPP/1.1 that has (type3 keyword | name(MAX)).
Changes to create the January 28, 2000 version
