Hello all.
I thought this little bit of information might help anyone who has ever
wanted to print out MAN pages to an HP LaserJet, and is sick and tired
of things going wrong, no italics, propper bolding etc.

I have never seen an man macros that will format output for a LaserJet,
so I took a rather sneaky path to a solution:

When you use either NROFF or TROFF, you can specify, via the -T option,
what terminal you wish the output to be formatted for. The files which
are used when you use the -T option are found in /usr/lib/term.

Below is a C file for a LaserJet "terminal" which you can pass to either
NROFF or TROFF. The file is called tabljet.c. Put this file in /usr/lib/term
and do the following:

cc -O -c -M0 tabljet.c
cc -o mkterm -M0 mkterm.o tabljet.o

This will create an executable "mkterm". Run this program, and it will
create a file called "tabljet". This contains all the necessary escape
sequences for propper bolding, italics etc. I use it all the time now
for printing man pages on the LaserJet. To format output for the laser
just type in nroff -man -Tljet filename | tbl > outfile.

This will format file filename using all the escape sequences, and send
it to the file outfile. Just print this file and your man pages look
quite spectacular.

I hope this helps and is of some use to you all.

Oh, BTW, this was done for Xenix/386, and you need the development system.
I'm not sure if this scheme of getting terminal info from /usr/lib/term
applies to other flavours of Unix, but it might.
