There are two types of companies involved in the PWG/C:
The consumer devices focus on:
peer to peer printing
inter-operability of the PC environment and the PC-less environment
PWG/C Charter is similar to the one developed by the 1394PWG committee.
Please refer to the presentation for more details on this.

committee. The PWG/C operates with a Steering Committee which sets the
agenda for the meetings. The current SC members are:
Apple Japan, Canon, Seiko Epson, Fuji Photo Film, Fuji Xerox, Microsoft
K.K., NEC, Sony and Sharp.
Membership in the committee is open to any company wishing to contribute to
The PWG/C has an aggressive schedule for the development of the printing
standards. The current schedule is:

Overview of PWG1394 charter
PWG/C is concerned about the distinction between "peer to peer" and "PC
Need to determine the needs of the consumer side vs the PC side=20
Through the ensuing discussion it was determined that the requirements for
the PWG/C and the 1394PWG are essentially the same. The only differences
is in the interpretation of "peer to peer" and "PC less" printing. Both
committees are concerned with the development of printing from any source
to any target. The wording will be worked on to make this clearer.
Coordination with 1394TA
The 1394PWG needs to clarify the relationship with the TA.
Greg Leclair will be representing the 1394PWG at the next 1394TA meeting,
April 16. Part of his=20
goal is to:
Make a presentation at the general TA meeting
Get a link on the TA web site to the 1394PWG
It is our goal to be sure the 1394TA refers printing related inquiries to
Coordination with PWG/C in Japan
Develop a unified charter with the tasks assigned to the different groups.
Since the goals of the committees are essentially the same, we should try
to establish a common charter to work from. We want to make sure that we
are not both trying to solve the same problems. With a common charter and
a closer working relationship we can divide the project into tasks that can
be worked on by either committee, or jointly, as necessary. It was decided
that the purpose of the second day meeting will be to work on the joint
charter. This will then be discussed at the next PWG/C meeting the week of
Need a new phrase for "peer to peer".
All proposals will be posted on the PWG.ORG server
June 11-12 joint meeting in Tokyo =96 Microsoft
How can we coordinate email?
Proposal to have one group - 1394PWG, with 2 sub-committees dealing with
the issues of consumer and PC oriented printing. The 1394PWG chair will be
the official liaison with the TA.
This was agreed to here and will be discussed in Japan by the PWG/C.
IEEE Study Group
This project is officially an IEEE study group under the Microprocessor
Standards Committee (MSC). We
have until the July 1997 MSC meeting to determine if we want to become a
full working group and present a Project Authorization Request (PAR) form.
Larry Stein (MSC recording secretary) and Don Wright (MSC vice-chair) will
keep the MSC abreast of this committees development.
May 14 -- San Diego
June 11-12 =96 Tokyo, hosted by Microsoft
June 24-25 =96 Boston
If we have enough to talk about then we can schedule a teleconference
