No idea if these drivers would work on an Intel-based Mac, if that's what you have. But you'd need a USB to serial converter (which may not work, since if memory serves that printer had a special high-speed serial port that needed to be externally clocked, something the converts won't so) unless the printer came with an Ethernet port (it was optional) and for the cost of such a converter you could almost purchase a new inkjet printer that would be far superior in speed and print quality (NewEgg has Mac-compatible inkjet printers for under $30.00 US). So if it were me I wouldn't bother trying to get it to work.
