A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Internet Printing Protocol Working Group of the IETF.
Title : Internet Printing Protocol/1.0: Model and Semantics
Author(s) : P. Powell, T. Hasting, R. Herriot, S. Isaacson, R. deBry
Filename : draft-ietf-ipp-model-07.txt
Pages : 144

This document is one of a set of documents, which together describe
all aspects of a new Internet Printing Protocol (IPP). IPP is an
application level protocol that can be used for distributed printing
using Internet tools and technologies. The protocol is heavily
influenced by the printing model introduced in the Document Printing
Application (DPA) [ISO10175] standard. Although DPA specifies both
end user and administrative features, IPP version 1.0 (IPP/1.0)
focuses only on end user functionality.
The full set of IPP documents includes:
Requirements for an Internet Printing Protocol [IPP-REQ]
Internet Printing Protocol/1.0: Model and Semantics (this document)
Internet Printing Protocol/1.0: Protocol Specification [IPP-PRO]
Rationale for the Structure and Model and Protocol for the Internet
Printing Protocol [IPP-RAT]
The requirements document, ''Requirements for an Internet Printing
Protocol'', 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. The requirements document calls
out a subset of end user requirements that MUST be satisfied in
IPP/1.0. Operator and administrator requirements are out of scope for
version 1.0. This document, ''Internet Printing Protocol/1.0: Model and
Semantics'', 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 protocol specification, ''
Internet Printing Protocol/1.0: Protocol Specification'', is a formal
mapping of the abstract operations and attributes defined in the model
document onto HTTP/1.1. The protocol specification defines the
encoding rules for a new Internet media type called ''application/ipp''.

Send a message to: mailserv at ds.internic.net. In the body type:
"FILE /internet-drafts/draft-ietf-ipp-model-07.txt".
NOTE: The mail server at ds.internic.net can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
