Serial-port -> Parallel printer

[King Chattam]

Hi netters,
  I am administering a XENIX with 48 serial ports and single parallel port.
I have to connect 4 parallel printers (proprinter, Qume, Nec). Some of the
printers have only parallel ports. I do not have Logical connection or similar
converters. Is there a simple way I can connect a serial port of the computer
with a parallel printer? Can I try special "connector pins" to adapt the
parallel port of my printers? Any information will be appreciated.
