>I have a colour Tek laserprinter and wish do to accounting.

If you mean Tektronix, they used to provide a "hybrid" port that would
allow sending data to the printer on the parallel connection and receiving
status from the serial connection (this was on a pre-PostScript color
printer, I don't recall the model number).  Using this would require either
hacking TranScript's pscomm driver (to listen on the serial port while sending
to the parallel port) if you have source, or else writing your own listener
process to do accounting for this printer.
