[comp.laser-printers] Help: TCP/IP to Printers/Imagesetters

dave@chelgraph.UUCP (03/14/91)

My company (Chelgraph) makes and sells Imagesetting equipment. We
are developing an Ethernet interface to these products, and want to
support the TCPIP protocols.  Just saying "TCPIP" does not, however,
completely define the interface: what higher level protocol should
be used to talk to the printer (e.g. FTP) ?  We do not want to
re-invent the wheel.

There must be standards already in existence for talking to printers
(e.g. DEC, Linotype). Could any users of these printers provide
advice or pointers to any reference information that would help me ?

Thanks. David

The specifications for Digital's TCP/IP laser printer protocol are
public documents. They are on file with Jon Postel, as the
documentation associated with the use of TCP socket 170. You can also
order a copy of these documents from my laboratory's librarian; send
e-mail to wrl-techreports@decwrl.dec.com to talk to an ordering robot.

The protocol used to talk to the Unix lpd daemon is described
in RFC 1179,  "Line Printer Daemon Protocol", dated August
1990. Check the comp.protocols.tcp-ip newsgroup if you need
more help. (I actually pruned this from a recent request in
comp.protocols.tcp-ip.ibmpc.)
