I missed the original thread. The subject line didnt mention anything about
printers, so i didnt read em ;) So, it would help me if you briefly restated
the exact problem. I'm assuming you have a calcomp plotter (but i dont
know which one), that it has a M971 ethernet card, and that you dont know
what the IP address is set to. And that you insist on using the ethernet
port, versis connecting it via parallel port to a unix server.

Well, one way of solving this problem is to reset the M971 card back to
factory defaults, and then setting the IP address. Unfortunately I dont
have the manuals, but if you have the manuals you should be able to look
some of this up. There is a reset jumper on the ethernet card, so you
power down the printer, remove the card, install the jumper, power it up,
then repeat to remove the jumper (assuming i recall the procedure correctly).

If the IP is reset back to 0.0.0.0, then the second step is to use the
reverse-ARP procedure to set the IP address. And i really dont recall that
procedure off the top of my head, but you need the LAN address from the
M971 card, which you then add to the ARP tables on a unix host on the local
subnet, etc, etc... There is a certain pattern to the indicator lights on
the M971 that tells you that it is waiting to recieve the RARP, if you
can find that extremely thin M971 manual.

Once you get the IP set via RARP method, telnet to the printer and use
the menu to set it permanently.

This would be the method for a Calcomp DrawingMaster 800 with M971 ethernet
card installed.
