Internet Printing Protocol/1.1: Encoding and Transport
draft-sweet-rfc2910bis-00
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
material or to cite them other than as "work in progress."
This Internet-Draft will expire on October 27, 2015.
