How are you submitting this to the printer? I use the print spooler
(for which the setup seems to be one of the more challenging aspects
in Unix) and pass it nroff output which includes various control
codes.

I would guess that if you use something like 'cat >/dev/lp0' that cat
might strip out control codes.
