Hi Glen,
Do you think accepting your proposal for the device (i.e. printer) and
making it available to both the client and the printer could work?
It means that not all IPP Everywhere conforming clients and printers would
necessarily be interoperable and it would support Justin's position that in
this specific area market need should drive the discovery and the document
formats a particular vendor found their customers reported were must haves.
Just a thought .
Best Regards,
/Paul

Mike (all)
The change below pushes the burden to the printer (at an increased cost to
the printer) while the Client, a software entity, has less burden. What is
wrong with
1. Discovery:
a. Clients MUST support DNS-SD and WS-Discovery
b. Printers MUST support either DNS-SD or WS-Discovery and RECOMMENED to
support both.
2. Document Formats:
a. Clients MUST support both JPEG and PWG Raster
b. Printers MUST support either JPEG or PWG Raster and RECOMMENDED to
support both.
This change to the printer requirements could mean a faster time to market
since printers are already support one of the discoveries and documents
formats but may not support both discoveries and document formats.
As was discussed in the meeting, if either discovery or document format
change in the future, the backward compatibility burden would have to be on
the Client to deal with legacy printers. There 'may' be an issue of Client
legacy but I content that is still easier to update Clients rather than
printer firmware. In the event of a Cloud Print Service or a Print
Manager; then, I would assume the "RECOMMEDED" support of both would be
implemented.

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.
