CURRENT_MEETING_REPORT_
Reported by Glenn Trewitt/DEC
NPP Minutes
We reviewed the goals of the Working Group (problems to be solved) and
looked at how the problem could be partitioned into smaller subproblems.
Three subproblems stood out:
1. Wire Protocol
There is an immediate need among some vendors (notably those who
make terminal servers) to have a standard that they can implement
that provides the capability to create a TCP connection to one (of
many) hardware ``byte-stream'' interfaces (either serial or
parallel). The path must be capable of being 8-bit clean. It
would be a good thing for the protocol to provide a mechanism for
supporting ``rotary groups'' for groups of printers.
2. Printer Access
Communication to a printer that has some sort of direct network
connection. Presumably, the printer has its own IP address. The
source of the print job is unspecified -- it might just be
someone's PC, or a full-blown print manager and spooler. There are
many requirements here: authentication, accounting, capability
negotiation (what page description languages are supported, paper
sizes, special features, etc.), etc.
3. Job Submission Communication from someone who has a document to be
printed to a printing manager/spooler. The current popular example
of this is the lpr/lpd protocol, which most people seem to feel is
inadaquate for more complex printing environments.
Decisions and Action Items
We quickly decided that problem (1), the wire protocol, deserved a
general solution in a broader context, since there are a number of other
applications that require it, such as data collection, modem pools, and
``milking-machine'' concentrators. Russ Hobby agreed, and suggested
that we take that protocol project to the Telnet Working Group. Bill
Westfield (cisco) agreed to do this.
In response to problem (2), Ajay Kachrani (DEC) proposed that we adopt
the ``Printer Access Protocol''. This is the protocol used to
communicate with Digital's networked PostScript printers. He handed out
a description of it, which I will make available via anonymous FTP.
Richard Hart (DEC) has proposed that we address problem (3) by adopting
the Palladium printing archictecture, developed at MIT's project Athena.
I suggested that we contact Adobe Systems, to see what input they could
1
provide about printing architectures. I have since talked to Carl
Orthlieb and Sherri Nichols at Adobe. They will be providing four
documents about Adobe's model of printing architecture, and will
participate in our activities as well.
I will shortly be setting up a directory (accessible via anonymous FTP)
containing the Adobe documents, some relevant DEC Western Research Lab
technical notes, as well as the documents about the two proposals (PAP
and Palladium).
Other Activities
Leo McLaughlin and Robert Knight finished RFC 1179, documenting the
Berkeley Line Printer Daemon Protocol.
