Subject: Re: [IPP] IPP Everywhere and "The Great Compromise"
After letting this sink in over the past couple days, I have to pull my
support for allowing a client to only support JPEG. Aside from the
quality issues, JPEG does not support multiple page content and so does
not satisfy the requirements set forth in the IPP Everywhere spec and
current charter. That leaves us with:
1. Discovery:
a. Printers MUST support both DNS-SD and WS-Discovery (adds WS-Discovery)
b. Clients MUST support DNS-SD and/or WS-Discovery (Clients can choose
amongst the two required protocols)
I humbly suggest that the <1000 lines of code (CUPS' implementation is 830
lines for both read and write) needed to generate PWG Raster is not an
undue burden on clients to implement support for and conform to IPP
Everywhere.
Please comment, and we will review this at the next IPP conference call on
September 10th.

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.
