On the chance that he is having to repeat my efforts with wordstar, I had
to write a serial printer driver for Wordstar 3.01 years ago...  If he needs
it (to crib code from if nothing else) I'll be happy to send it to him.
It sits in the patch space, and opens a file and then procedds to dump all
printer output to it.  When the printer is done, the file is closed, all
neat and pretty.  One of the projects on the stack is to hack my BIOS to
implement another redirection target (UL1: or something) to be a modification
of that old patch - to some file like OUT.OUT, which would then be renamed.
 
Or something.

Lastly, one kludge that I used one time was a serial print buffer, with the
output stalled with a ^S.  I dumped the file into it, then ran the
modem program, after it was up I started the capture function, swapped
ports on the buffer, and a ^Q sucked the file in.  It worked, but it took
a couple of tries and a breakout box to do it.

The opinions above probably do not even come close to those of my employer(s).
