Appendix A: Allowed Values for Set-Printer-Attributes and Set-Job-Attributes requests (Normative)

This appendix is a normative part of this document and contains a table of all IPP/1.1 attributes. Each row contains: - an attribute and - the values allowed in the Set-Printer-Attributes or Set-Job- Attributes request for the attribute. The entry in each cell is the name (first few words) of each item below 1, 2, 3, 4a-g, and 5. The allowed values include the following cases: 1. READ-ONLY: the Set-Printer-Attributes or Set-Job-Attributes operation MUST NOT change this attribute and MUST reject the entire operation (see section 7.1). 2. Any of "xxx-supported": the Set-Printer-Attributes or Set- Job-Attributes operation accepts values that are allowed according to the IPP/1.1 rules for validating the value(s) of an "xxx" Printer or Job attribute against the value(s) of the corresponding "xxx-supported" Printer attribute. Table 5 summarizes those validation rules depending on each attribute syntax and value of an "xxx" attribute supplied in the request and that of the corresponding "xxx-supported" Printer attribute. The "xxx-supported" attribute syntax type and value(s) are obtained from a Get-Printer-Supported-Values response (see the tables in this Appendix).

          Table 5 - Validation rules for 'Any of "xxx-supported" '

      Type of "xxx"  Type of "xxx-      Validates if:
      value to be    supported" value
      set

      integer        rangeOfInteger     each value is in one of the
                                        "xxx-supported" ranges

      uri            uriScheme          each uri scheme matches one
                                        of the "xxx-supported"
                                        schemes

      any            boolean            if the boolean "xxx-
                                        supported" is 'true'

      any            same type          each value matches an "xxx-
                                        supported" value of the same
                                        type

   For additional non-normative explanatory information see section
   3.1.2.3 of the "Internet Printing Protocol/1.1: Implementer's Guide"
   [RFC3196].

      3. From Get-Printer-Supported-Values: the  Set-Printer-Attributes
         operation accepts values that are allowed according to the
         IPP/1.1 rules for validating the value(s) of an "xxx" Printer
         attribute against the value(s) of the corresponding "xxx-
         supported" Printer attribute.  Table 6 summarizes those
         validation rules depending on each attribute syntax and value
         of an "xxx" attribute supplied in the request and that of the
         corresponding "xxx-supported" Printer attribute.  The "xxx-
         supported" attribute syntax type and attribute value(s) are
         obtained from a Get-Printer-Supported-Values response (see
         Appendix B: Attributes returned from Get-Printer-Supported-
         Values below).

       integer     rangeOfInteger    each 'integer' value is in one of
                                     the "xxx-supported" ranges

       uri         uriScheme         the uri scheme of each value
                                     matches one of the "xxx-supported"
                                     schemes

       any         boolean           if the boolean "xxx-supported" is
                                     'true'

       name        'admin-define'    any 'name' value matches
                   out-of-band
                   value

       any         same type         each value matches an "xxx-
                                     supported" value of the same type

   For additional non-normative explanatory information see section
   3.1.2.3 of the "Internet Printing Protocol/1.1: Implementer's Guide"
   [RFC3196].

      4. Any value of the proper attribute syntax: the Set-Printer-
         Attributes or Set-Job-Attributes operation accepts any value of
         the specified attribute syntax.  The attribute syntaxes
         supported are enumerated below.

            a. Any text(127)
            b. Any name(127)
            c. Any uri
            d. Any boolean
            e. Any positive integer
            f. Any dateTime
            g. 1setOf any uri

      5. Combination of 'Any of "xxx-supported"' or 'Any name'.  If a
         Printer implementation doesn't want to allow setting values
         indicated in this Appendix as "any xxx", it can make the value
         be not-settable.

Appendix B: Attributes returned from Get-Printer-Supported-Values (Normative)

This Appendix is a normative part of this document and lists all the attributes that are possible for an implementation to return in a Get-Printer-Supported-Values response, i.e., all the "xxx-supported" attributes that can be supplied in a Set-Printer-Attributes request. READ-ONLY attributes MUST NOT be returned in a Get-Printer- Supported-Values response and are indicated in the tables as "READ- ONLY - MUST NOT be returned." For the following attributes, the value allowed by the Set-Printer- Attributes operation MUST be a single integer value in the range specified by the value returned by the Get-Printer-Supported-Values operation.

   For Job Template attributes, with the attribute syntax 'type3 keyword
   | name', any 'name' attribute syntax value matches the 'admin-define'
   out-of-band value, if the implementation allows the administrator to
   set any name values for the attribute.

Appendix C: Description of the Base IPP Documents (Informative)

The base set of IPP documents includes: Design Goals for an Internet Printing Protocol [RFC2567] Rationale for the Structure and Model and Protocol for the Internet Printing Protocol [RFC2568] Internet Printing Protocol/1.1: Model and Semantics [RFC2911] Internet Printing Protocol/1.1: Encoding and Transport [RFC2910] Internet Printing Protocol/1.1: Implementer's Guide [RFC3196] Mapping between LPD and IPP Protocols [RFC2569] The "Design Goals for an Internet Printing Protocol" document takes a broad look at distributed printing functionality, and it enumerates real-life scenarios that help to clarify the features that need to be included in a printing protocol for the Internet. It identifies requirements for three types of users: end users, operators, and administrators. It calls out a subset of end user requirements that are satisfied in IPP/1.0 [RFC2566, RFC2565]. A few OPTIONAL operator operations have been added to IPP/1.1 [RFC2911, RFC2910]. The "Rationale for the Structure and Model and Protocol for the Internet Printing Protocol" document describes IPP from a high level view, defines a roadmap for the various documents that form the suite of IPP specification documents, and gives background and rationale for the IETF IPP working group's major decisions. The "Internet Printing Protocol/1.1: Model and Semantics" document describes a simplified model with abstract objects, their attributes, and their operations. The model introduces a Printer and a Job. The Job supports multiple documents per Job. The model document also addresses how security, internationalization, and directory issues are addressed. The "Internet Printing Protocol/1.1: Encoding and Transport" document is a formal mapping of the abstract operations and attributes defined in the model document onto HTTP/1.1 [RFC2616]. It also defines the encoding rules for a new Internet MIME media type called "application/ipp". This document also defines the rules for transporting over HTTP, a message body whose Content-Type is "application/ipp". This document defines the 'ipp' scheme for identifying IPP printers and jobs. The "Internet Printing Protocol/1.1: Implementer's Guide" document gives insight and advice to implementers of IPP clients and IPP objects. It is intended to help them understand IPP/1.1 and some of the considerations that may assist them in the design of their client

   and/or IPP object implementations.  For example, a typical order of
   processing requests is given, including error checking.  Motivation
   for some of the specification decisions are also included.

   The "Mapping between LPD and IPP Protocols" document gives some
   advice to implementers of gateways between IPP and LPD (Line Printer
   Daemon) implementations.
