This document is an OPTIONAL extension to the Internet Printing Protocol (IPP/1.0 and IPP/1.1). This document specifies 3 additional OPTIONAL operations for use with the Internet Printing Protocol/1.0 (IPP) and IPP/1.1. The end user, operator, and administrator Set- Job-Attributes and Set-Printer-Attributes operations are used to modify IPP Job objects and Printer objects, respectively. The Get- Printer-Supported-Values administrative operation returns values that the IPP Printer will accept for setting its "xxx-supported" attributes.
