	Title		: Internet Printing Protocol (IPP): IPP Event 
                          Notifications and Subscriptions

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 sends 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.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
