thanks for the comments submitted by Bill, Don and Jay. This new version has
taken their proposed changes into account, except for the following two
points that I did not think were supported by the whole group:
1) Bill suggested that the wording about "authentication etc." was too
strong. I believe that the security aspects cannot be underrated when we aim
for an Internet standard (as opposed to intranets, where security behind
firewalls may be more relaxed). I changed "shall" to "will" if that is
considered an improvement? Comments?
2) Jay was uncertain about keeping the formulation about "extensibility
paths". We do have this in DPA, and I believe that this is a very important
design feature that we need to carry over into the IPP version. Is there
really disagreement about this point?
What still needs to be done is to add references to the Internet-Draft(s) at
the end of the document.
As this is a short document, I skipped trying to make line numbers and
revision marks.
I hope that we can reach agreement on the text tomorrow...

Editor: Scott Isaacson <scott_isaacson@novell.com> 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 not strive to preclude any types of output devices (e.g., fax, printer, gateway). Also, the working group shall define extensibility paths so that similar extensions will interoperate and proprietary, dissimilar extensions will never 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 replace RFC 1179 'Line Printer Daemon Protocol'. LPR/LPD was designed a long time ago with line printers in mind. It does not fit with current page oriented printing technologies.
