Using fonts while formatting documents

[Mohan Palathingal]

Sir,
I am attempting to use some fonts available on my mainframe system while
formatting my documents. If I am not mistaken we need an XROFF formatter to
do the job (or TROFF). Apparently only NROFF seems to work and is not capable 
of doing the font change. I use a Zenith (IBM compatible) and also have a
XEROX 4045 laser printer avaiable. The fonts I need are in the directory
"/usr/lib/xroff/fontimc/". 
If you can give me some guidance, I would greatly appreciate it.
Thanks.
