[net.wanted] filter to allow underlining on a Printronix printer needed

bytebug@pertec.UUCP (roger long) (08/17/84)

I need a filter to convert the output from nroff that contains
underline-backspace-letter combinations into something that
a Printronix printer understands.  Our Printronix printer
doesn't print until it receives a line feed.  If you wish to
underline something, you must print the line, send a carriage
return and "overstrike" the underlines.  Does anyone have 
something to do this, or am I overlooking a standard tool?

Hints, suggestions, and/or code gratefully accepted.

Thanks.
