         Internet Printing Protocol/1.1: Encoding and Transport
                       draft-sweet-rfc2910bis-04

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 defines the
   rules for encoding IPP operations and IPP attributes into 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.

Editor's Note

   This draft is being submitted in preparation for a so-called "fast
   track" IETF IPP WG, with drafts being reviewed and edited by the
   IEEE-ISTO's Printer Working Group IPP WG, in order to correct known
   editorial issues and advance IPP/1.1 to IETF Internet Standard.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
