Printer Working Group. In March 1997, the IETF Internet Printing Protocol working group was chartered. This working group published a series of IPP RFCs from 1999 through 2005, at which point development and maintenance of IPP transitioned to the Printer Working Group. In September 1999, the IEEE formalized an alliance with PWG as part of the IEEE Industry Standards and Technology Organization (IEEE-ISTO). Since then, the PWG has published over 60 standards and informational documents related to printing and printers. In March 2015, the IETF published a new IPP RFC developed by the PWG IPP workgroup - RFC 7472: IPP over HTTPS Transport Binary and the ipps URI Scheme. In January 2017, the IETF published updates to the core IPP RFCs (RFC 2910, 2911, 3381, and 3382) developed by the PWG IPP workgroup - RFC 8010: Internet Printing Protocol/1.1: Encoding and Transport and RFC 8011: Internet Printing Protocol/1.1: Model and Semantics. In June 2018, the IETF published these RFCs as Internet Standard 92. References Information technology organizations Computer printers Working groups
