I have a QMS PS-810 that I'd like to use in the following non-standard way:

Currently the printer is connected through its parallel port (switch setting
4 in the back) because that is significantly faster than the serial
communications, especially when downloading images.  However, when connected
by the parallel port, there seems to be no stdout file available.  What I would
like to do is somehow either 1) redirect stdout to the 25 pin serial channel
(9600 baud would be nice) or if that's not possible 2) open the 25 pin
serial channel as a file object, in either case maintaining the parallel line
as the stdin file.

TFM manual doesn't say anything more than "use switch 4 for parallel, and
use switch position 1 for serial on the 25 pin channel."

Thanx in advance for any help.

Please respond by e-mail as I haven't the time to read this group regularly.
(Even though this looks like an interesting one).
