Help with 3100 printer port

[Kevin Ruddy]

I've got an /etc/printcap entry all set up for a PostScript printer
(an HP LaserJet IIID) and the appropriate cable to plug into the
printer port.  (Or the comm port?  I don't know which ...)  However,
I have no idea what the entry is in /dev is so that I can actually
send stuff down the pipe!

Help!  And we've managed to lose our 2100/3100 hardware-specific manual.

Any help would be greatly appreciated!
