Internet Printing Protocol Workgroup

Charter

The Internet Printing Protocol workgroup is developing standards for IPP-based multi-function services such as scanning and facsimile as well as 3D printing, is developing the PWG Semantic Model Print3d Service Schema, and is responsible for maintaining the IANA IPP, Printer MIB, Finisher MIB, and Job MIB registries. The workgroup also develops IPP Everywhere™ and manages the IPP Everywhere™ Printer Self-Certification program.

Officers

Co-Chairs: Ira McDonald, Paul Tykodi
Secretary: Michael Sweet
