This sounds normal. If no printer is given, "lp" is the name
that will be addressed. It is the _default_ printer name that
the lp* tools refer to. If your printer is named differently,
you need to specify -P<name> according to the printcap entry.
You can also define $PRINTER (for example in /etc/csh.cshrc
globally) with the name of the printer.

For example, I have this setting (among others):


It's my default printer, so I set $PRINTER to "Laserjet", and
when I invoke lpr, lpq or lprm, this printer's queue will be
used. For my nondefault printers, I have to use

	# lpq -PLaserjet-nodup

for example, but I hardly do this. :-)

In your case, $PRINTER would have to be set to "HP2100tn", or
you use -PHP2100tn (at least for testing).

See "man printcap" for this.

A Postscript printer? Excellent, this should work without any
problems. But I don't see how modifying the printer filter
should help...

Anyway, consult

for more helpful advice. :-)
