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

How hard did you look?

Note that it claims that it's not IEEE compatible. It also claims that
it wont work with HP printers, but that part is not necessarily true; it
depends upon the printer.

This one is automatic:

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