Alas the PC protner port was so well-designed.

_Many_ years ago, I needed to get plotter output from
a CoCo3, and all I
could get my hands on was an HPIB plotter. I ended up using a Commodore
PET (8032SK) with a 8050 drive to load the program from, and a 3rd party
RS232 itnerface unit. The PET just read chracters from the RS232
interface and sent them to the plotter. Overkill, sure, but it worked
(and yes, I do still ahve all the bits of that system)
I have used an XT as a serial to parallel converter, and as a parallel to
serial converter, etc. For me, that has almost always been cheaper than
the appropriate purpose designed hardware.
