Abstract


This document specifies additional type3 keyword values for the IPP/1.1
"media" Job Template attribute for use with the Internet Printing
Protocol/1.1 (IPP).  These additional attribute values permit the client
to specify additional media options, including values of media common to
engineering drawings.  For completeness, all of the existing "media"
keyword values are included as well.

INTERNET-DRAFTIPP/1.1: "media" attribute values extensionOctober 8, 1999


The full 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 [ipp-mod]
   Internet Printing Protocol/1.1: Encoding and Transport [ipp-pro]
   Internet Printing Protocol/1.1: Implementer's Guide [ipp-iig]
   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.  A few OPTIONAL operator operations have been
added to IPP/1.1.


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
working group's major decisions.


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 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 a
new scheme named 'ipp' 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 is 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.

1  Additional values for the "media" Job Template attribute


1.1 Problem


Need additional type3 keyword values for media to support the additional
sizes and types of media common to engineering drawings.

1.2 Suggested solution


This solution is a new solution to address the unique requirements for
the engineering market.  The suggestion is to add additional type3
keyword values to the "media" Job Template attributes (also applies to
"media-default", "media-supported" and "media-ready" attributes).



1.3 Proposed Text


Add the following paragraphs indicated with revision marks to the
description of the "media" Job Template attribute (section 4.2.11),
References (section 9), and Appendix C: "media" keyword values (section
14), so that the entire sections would be:

4.2.11 media (type3 keyword | name(MAX))

This attribute identifies the medium that the Printer uses for all
impressions of the Job.


The values for "media" include medium-names, medium-sizes, input-trays
and electronic forms so that one attribute specifies the media. If a
Printer object supports a medium name as a value of this attribute, such
a medium name implicitly selects an input-tray that contains the
specified medium.  If a Printer object supports a medium size as a value
of this attribute, such a medium size implicitly selects a medium name
that in turn implicitly selects an input-tray that contains the medium
with the specified size.  If a Printer object supports an input-tray as
the value of this attribute, such an input-tray implicitly selects the
medium that is in that input-tray at the time the job prints.  This case
includes manual-feed input-trays.  If a Printer object supports an
electronic form as the value of this attribute, such an electronic form
implicitly selects a medium-name that in turn implicitly selects an
input-tray that contains the medium specified by the electronic form.
The electronic form also implicitly selects an image that the Printer
MUST merge with the document data as its prints each page.


Standard keyword values are taken from ISO DPA, the Printer MIB and
ASME-Y14.1M and are listed in section 14. An administrator MAY define

additional values using the 'name' or 'keyword' attribute syntax,
depending on implementation.


There is also an additional Printer attribute named "media-ready" which
differs from "media-supported" in that legal values only include the
subset of "media-supported" values that are physically loaded and ready
for printing with no operator intervention required.  If an IPP object
supports "media-supported", it NEED NOT support "media-ready".


The relationship of this attribute and the other attributes that control
document processing is described in section 15.3.


The following text includes all of the current Appendix C in [ipp-mod]
plus additional values:

2  IANA Considerations


These "media" type3 keyword attribute values will be published by IANA
according to the procedures in RFC 2566 [rfc2566] section 6.1 with the
following URL:

     ftp.isi.edu/iana/assignments/ipp/attribute-
     values/media/engineering.txt


3  Internationalization Considerations


Normally a client will provide localization of the keywords values of
this attribute to the language of the user.  On the other hand, the
client will not localize any name values for the "media" attribute
defined by the system administrator of the IPP Printer (see [ipp-mod]
section 4.1.2 and 4.1.3).


4  Security Considerations


This extension poses no additional security threats or burdens than
those in IPP/1.0 [RFC2566, RFC2565] and IPP/1.1 [ipp-mod, ipp-pro].
However, implementations MAY support different access control to various
media, depending on the identity of the job submitting user.
