[IPP] IPP Everywhere and "The Great Compromise"

[Michael Sweet]

All,

We discussed the PWG Last Call comments received thus far at today's IPP WG conference call.  Two of the comments concerned the client requirements to support DNS-SD for discovery and both PWG Raster and JPEG for document formats.  After over an hour of spirited debate, the following "great compromise" was proposed to resolve the last call comments:

1. Discovery:

   a. Printers MUST support both DNS-SD and WS-Discovery (adds WS-Discovery)
   b. Clients MUST support at least one of DNS-SD and WS-Discovery (Clients can choose amongst the two required protocols)

2. Document Formats:

   a. Printers MUST support both JPEG and PWG Raster (no change)
   b. Clients MUST support at least one of JPEG and PWG Raster (relaxes conformance - previously a Client had to support both)

Please comment on the proposed changes.
