Internet Printing Protocol (IPP): Requirements for Job, Printer, and Device Administrative Operations

RFC 3239        IPP: Req. for Job and Printer Admin Ops    February 2002


1 Introduction

   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 ([RFC 2911, RFC 2910]) focuses on end
   user functionality with a few administrative operations included (for
   a description of the base IPP documents, see Appendix A).  This
   document defines the requirements and use cases for additional
   optional end user, operator, and administrator operations used to
   control Job objects, Printer objects (see [RFC 2911]) and a new Device
   object.  The new Device object more closely models a single output
   device and has no notion of a job, while the Printer object models a
   print service which understands jobs and may represent one or more
   output devices.

   The scope of IPP is characterized in RFC 2567 [RFC 2567] "Design Goals
   for an Internet Printing Protocol".  It is not the intent of this
   document to revise or clarify this scope or conjecture as to the
   degree of industry adoption or trends related to IPP within printing
   systems.  It is the intent of this document to extend the original
   set of operations - in a similar fashion to the Set1 extensions which
   referred to IPP/1.0 and were later incorporated into IPP/1.1.

2 Terminology

   This section defines terminology used throughout this document and
   the corresponding documents that define the Administrative operations
   on Job, Printer, and Device objects.

   This document uses terms such as "client", "Printer", "Job",
   "attributes", "keywords", and "support".  These terms have special
   meaning and are defined in the model terminology [RFC 2911] section
   12.2.

   In addition, the following capitalized terms are defined:

      IPP Printer object (or Printer for short) - a software abstraction
         defined by [RFC 2911].

      Printer Operation - an operation whose target is an IPP Printer
         object and whose effect is on the Printer object.

      Output Device - the physical imaging mechanism that an IPP Printer
         controls.  Note: while this term is capitalized in this
         specification (but not in [RFC 2911]), there is no formal object
         called an Output Device.
