So you want Linux to pretend to be a printer, right? This isn't possible
at the moment I'm afraid, but it's not the first time that it's been asked

All you really need is the right cable (LapLink perhaps? I'll have to
check the pin assignments) and a small driver that reads the data port
each time it gets an interrupt and then acks it using whichever control
line. It shouldn't be hard, given the right cable.
