Multiple parallel printer interface for PC

I need to hook up 3 or more parallel printers to one PC. I'm not aware
of any such device in the marketplace and not expecting one since the
advent of USB. I must work with parallel printers for reasons I won't
go into here.

Presently I'm shifting the one cable from the PC to each printer as I
need to.

I'm thinking of three banks of tri-state drivers for the inputs and
outputs and making them switch selectable. Sound reasonable?

Does anyone have a pinout of the PC parallel port?

I suspect the outputs and inputs are buffered but I don't know that
for sure.

Any help would be appreciated.

Thanx

add an additional LPT card. I have a PCI card here that adds two more
parallel ports.
