Technical Summary These documents describe extensions to the Internet Printing Protocol/1.1: Model and Semantics (RFC 2911, RFC 2910). The first 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). The second extension is the 'ippget' Pull Delivery Method for use with the Event Notifications extension. This IPPGET Delivery Method is REQUIRED for all clients and Printers that support ipp-ntfy. The Notification Recipient, acting as a client, fetches (pulls) Event Notifications using the Get-Notifications operation. The final document in this set provides a statement of the requirements for notifications as part of an IPP service. Working Group Summary These documents are products of the Internet Printing Protocol Working Group of the IETF. The Working Group originally developed a general printer notification framework and three notification schemes, two based on IPP operations and one based on email. However, a previous IESG review pass caused the Working Group to eliminate two of the schemes and move forward with ippget alone. Protocol Quality Ned Freed and Scott Hollenbeck reviewed the specification for the IESG.
