Hmm.  You don't need a driver exactly (you could do it that way, but it's
overkill by a long way).

You'll find that picking a printer name just does a lookup in the text file
/etc/printers (q.v.) and picks a very simple shell script which you'll find
in /usr/spool/lp/model/  There are only two of these; they don't really know
anything about your printer.  Your problem is that nroff doesn't either.

The script gets renamed and moved to /usr/spool/lp/interface.  You may need
to write a filter for your printer, and put it in the pipeline that is the
heart of the interface script.

I did this for my various printers (Okidata 92 and ATT471), just to optimize
print head motion, reduce noise, and speed up all that overstriking and
underlining.  Presumably you're having trouble with ^H (backspace) and the
half-line and reverse linefeeds.  Find out how your printer does these and
it's not hard at all to write the filter.
