Harald and Keith,

We have now refined the earlier PWG Charter into a Proposed Charter for a WG
in the IETF, and would like your feedback if this is now OK.

Note that we recommend changing the title of the group to IPP, rather than
LDPA as previously suggested.

I have also included a revised agenda for the BOF meeting (including a title
Is there still a chance that we can still get the WG formed in time for the
San Jose meeting (our preference) or did we miss that boat? If so, can the
BOF be changed to become a WG meeting? If we become a WG in time for the
IETF meeting, the agenda needs some further updating. For that reason I have
not yet sent the revision to the IETF.

We are still polishing the texts on the two Internet-Drafts mentioned in the
Charter Draft. They will be finalized and sent to the IETF over the week-end.

I have about 15 people so far that has confirmed to me that they will show
up in San Jose for this subject. I have no doubt that we will get quite a
few more that I do not know about yet. This subject is certainly moving ahead.

Description of Working Group:

Internet printing involves using Internet technologies and services 
to find networked resources, such as printers, and then submit jobs
using those resources.  

The goal of this working group is to define a new application level 
distributed printing protocol as well as defining naming and service 
registration attributes for printing.  The protocol shall support a 
global, distributed environment where print service users (clients, 
applications, drivers, etc.) cooperate and interact with print service 
providers (servers, printers, gateways, etc.). 

The working group will leverage existing (and emerging) technologies 
for: authentication, authorization, privacy, and commercial transactions. 
For location of printers, the working group will leverage existing 
standards for directories.

The working group shall strive to coordinate its activities with other 
printing-related standards bodies.

The new job submission protocol should strive not to preclude any 
types of output devices (e.g., fax, printer, gateway).  Also, the 
working group will define extensibility paths to maximize interoperability 
and minimize conflict.

The Internet Printing Protocol will be designed to make use of Web 
browsers, HTTP, and LDAP for directory look-ups. 

The Internet Printing Protocol is intended to supplant RFC 1179 'Line 
Printer Daemon Protocol' as the preferred printing protocol. LPR/LPD 
was designed a long time ago with line printers in mind and does not 
fit with current needs.
