RFC 3380          IPP: Job and Printer Set Operations     September 2002


1 Introduction

   This document is an OPTIONAL extension to IPP/1.0 [RFC2565, RFC2566]
   and IPP/1.1 [RFC2911, RFC2910].  For a description of the base IPP
   documents see Appendix C.

   The Internet Printing Protocol (IPP) is an application level protocol
   that can be used for distributed printing using Internet tools and
   technologies.  IPP version 1.1 [RFC2911, RFC2910] focuses on end user
   functionality with a few administrative operations included.  This
   document defines additional OPTIONAL end user, operator, and
   administrator Set-Job-Attributes and Set-Printer-Attributes
   operations used to modify IPP Job objects and Printer objects,
   respectively.  It also defines a third Get-Printer-Supported-Values
   administrator operation that returns values that the IPP Printer will
   accept for setting its "xxx-supported" attributes.  The Get-Printer-
   Supported-Values operation MUST be supported, if the implementation
   supports setting any "xxx-supported" Printer attributes using the
   Set-Printer-Attributes operation.

   Nine Printer Description attributes are defined:

   printer-settable-attributes-supported (1setOf type2 keyword)
   job-settable-attributes-supported (1setOf type2 keyword)
   document-format-varying-attributes (1setOf type2 keyword)
   printer-message-time (integer(MIN:MAX))
   printer-message-date-time (dateTime)
   printer-xri-supported (1setOf collection)
   xri-uri-scheme-supported (1setOf uriScheme)
   xri-authentication-supported (1setOf type2 keyword)
   xri-security-supported (1setOf type2 keyword)

   Three out-of-band values are defined for use with these three
   operations: 'delete-attribute' for deleting Job attributes with the
   Set-Job-Attributes request, 'not-settable' for use in either the
   Set-Job-Attributes or Set-Printer-Attributes responses, and 'admin-
   define' for use in the Get-Printer-Supported-Values response.

   Two operation attributes: "printer-message-from-operator" (text) and
   "job-message-from-operator" (text) are defined to set the
   corresponding IPP/1.1 Printer and Job Description attributes with the
   same names.  These operation attributes may be used with any
   operation that affect the Printer or Job object for which an
   operation might want to indicate a message.  For the Set-Job-
   Attributes and Set-Printer-Attributes operations, the client MUST
   explicitly set them, rather than using these operation attributes.
