Sure, if you have a free EPP. I do not remember PC's coming with more then one. Moslty used for 'Printing'.

RS232 is most uncommonly used and converting to UART is simple, also making your own controller to accomplish this is trivial.
But if you rather forfeit your EPP for this go ahead.

Personally I'd go the microcontroller route.... I've set one up already that temp controls four voltage-controlled fans - much easier to receive RPM, temp and other status data over serial.
And I agree, deciding to add stuff such as a strobe is indeed trivial, if you know what you're doing.
Slightly off topic, but seeing the amount of people that don't read stuff in order to work software, I'm not about to start believing they'll have any luck with hardware. Some people just shouldn't be screwing with that stuff.
