This document describes an OPTIONAL extension to the Internet
Printing Protocol/1.1: Model and Semantics (RFC 2911, RFC 2910).
This extension allows a client to subscribe to printing related
Events.  Subscriptions are modeled as Subscription Objects.  The
Subscription Object specifies that when one of the specified Events
occurs, the Printer delivers an asynchronous Event Notification to
the specified Notification Recipient via the specified Push or Pull
Delivery Method (i.e., protocol).

A client associates Subscription Objects with a particular Job by
performing the Create-Job-Subscriptions operation or by submitting a
Job with subscription information.  A client associates Subscription
Objects with the Printer by performing a Create-Printer-Subscriptions
operation.  Four other operations are defined for Subscription
Objects: Get-Subscriptions-Attributes, Get-Subscriptions,
Renew-Subscription, and Cancel-Subscription.

This document is a product of the Internet Printing Protocol Working
Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
