Internet Printing Protocol/1

RFC 2566              IPP/1.0: Model and Semantics            April 1999


Abstract

   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.  This document describes a
   simplified model consisting of abstract objects, their attributes,
   and their operations that is independent of encoding and transport.
   The model consists of a Printer and a Job object.  A Job optionally
   supports multiple documents.  IPP 1.0 semantics allow end-users and
   operators to query printer capabilities, submit print jobs, inquire
   about the status of print jobs and printers, and cancel print jobs.
   This document also addresses security, internationalization, and
   directory issues.

   The full set of IPP documents includes:

     Design Goals for an Internet Printing Protocol [RFC 2567]
     Rationale for the Structure and Model and Protocol for the Internet
        Printing Protocol [RFC 2568]
     Internet Printing Protocol/1.0: Model and Semantics (this document)
     Internet Printing Protocol/1.0: Encoding and Transport [RFC 2565]
     Internet Printing Protocol/1.0: Implementer's Guide [ipp-iig]
     Mapping between LPD and IPP Protocols [RFC 2569]

   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.  Operator and administrator requirements
   are out of scope for version 1.0.

   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 specifications, and gives background and rationale for the
   IETF working group's major decisions.

   The "Internet Printing Protocol/1.0: Encoding and Transport" document
   is a formal mapping of the abstract operations and attributes defined
   in the model document onto HTTP/1.1.  It defines the encoding rules
   for a new Internet media type called "application/ipp".

   The "Internet Printing Protocol/1.0: Implementer's Guide" document
   gives insight and advice to implementers of IPP clients and IPP
   objects.  It is intended to help them understand IPP/1.0 and some of
