I have a HP Laserjet Series II with a Pacific Page postscript emulation
cartridge, hooked up to a 386 (DOS).  I want to make the thing print
faster and believe that most of the print time is in transmission.

I read somewhere that the data transmission to the printer would be
better if I used a serial connection than with the current parallel
one.  Even though the parallel interface transmits more bits per
cycle, the serial can run at a much higher cycle rate.

Does anyone know if this is true?  I think (my manauals are at home) that
serial can transmit at 9600 baud.  What is the speed of a parallel port?

Thanks in advance.

P.S.  If anyone wants a review of the Pacific Page, let me know.
