2.2.4.3 User Interface Messages

The following messages describe a set of request and reply exchanges that MAY be sent by either a client or a server. The primary purpose of these messages is to display a user interface (UI) on the client side and to provide the ability to cancel the UI from the server.

There are two sets of UI messages: printer properties messages and document properties messages. Both sets are similar in functionality but differ in the payload of properties that they establish.
