Someone requested printcap and filters a week or two ago.
Back when I was first bringing up 386BSD on my home
system, I occasionally wanted to print man pages.
I based my filter (sed script) upon what I could find
when I piped man pages to a file. I did this
because I found nothing in all my O'Reilly books or
on the system that sufficiently defined the troff
format for me. If the filter is still lacking
something, please let me know what it is and I
will try to add/change it.
Since I had not printed a man page in a long time,
I verified it last night on my 2.0.5 Release (CD) system:
man lpd | lpr -t
produced a nice hard copy, bold fonts and underline
worked well which make the printout easier to read.
This filter is for my Panasonic KXP4410 printer which
is supposed to be HPLJ IIP compatible.
For the person (people) having trouble with their printcap
file and Postscript printer, this is probably not the
problem but just FYI: Any time that I have changed my
printcap file, I have had to kill the running lpd daemon
and restart it manually (alternately, shutting down and
rebooting will work also) to have the changes recognized.
