Cool. I have an Epson Stylus Pro that works fine under ghostscript.

The convention, such as it is, is spelled out in the hier(7) man page.
My own printer filter is under /usr/local/libexec/lpr/.

`man -w' can help here. You could probably use that to write a little
script that will format the man page for it's argument, and send that
to the printer.

I've never seen that with the Stylus Pro. No idea.

I believe this is a known problem. For large files, use `lpr -s'. This
only puts a symlink in the spool directory, and the symlink _will_ be
deleted when finished.

Never seen that either. While experimenting with pap last month, I had
occasion to use lprm many times, and it worked fine, on both the
symlinks and the small files. (I'm running -current.) I do seem to
remember having problems making a printcap entry with any name except
"lp," so my only printer is named "lp." I comment out the Epson to use
pap, and vice-versa.
