The PC printer ports were bidirectional at least in the sense that they
had five status inputs which could be used as data inputs. Even the
control outputs could be fairly easily used as inputs which meant a
total 9 input pins.

Bidirectional ports have a control bit to set the data pins to inputs or
outputs or to be exact, eanble or disable the output drivers.

So, probably you can talk to a PC parallel port but I'd rather use
ethernet or serial (RS-232) for PC communication.
