Ok. Cheating to me would be to look at the code that someone else has done to write a parallel port driver. Where would I find documentation for common parallel port hardware? I have a Intel 440BX chipset, old I know, on this computer.
It's not cheating if you study the code to learn the protocol, and then write a new driver from scratch.
Or you could look at the code from another OS. DOS and OS/2 are good choices for this.
The parallel port interface is documented in tons of older PC programming books.
