Troff -t to IDS printer:

There is a guy at JHU named George Toth who wrote an output filter
that takes the CAT typesetter codes (from troff -t) and goes to the
versatec (this has been done other places, such as vcat at UofToronto).
His mail address is ...!brl-bmd!jhu!crw_rget

However!  If you are talking about the IDS IP-125 or 225 "Brighter
Writer" in it's so called graphics mode...FORGET IT.  We were thinking
about doing it and it is useless.  First...resolution is poor.  Second,
their is no way to generate constant spacing on the stupid thing.  Since
an octal 003 will take you out of graphics mode unless you place another
octal 003 after it, and a double 003 causes a glitch in the output, plotting
is not so hot .  What you really want to do is to fix up a nice terminal
description for nroff for the thing.

Note:  the thing also has the problem that it uses CTS for flow control,
but if you hit the right margin, it drops clear-to-send and then waits
for you to send a carriage return.  If you honor the CTS protocal you just
sit there and wait forever.
