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 1.1 semantics allow end-users and operators to query printer capabilities@ submit print jobs@ inquire about the status of print jobs and printers@ cancel@ hold@ release@ and restart print jobs. IPP 1.1 semantics allow operators to pause@ resume@ and purge (jobs from) Printer objects. This document also addresses security@ internationalization@ and directory issues.
