ok . . . i dont think you understand what im saying . . .
i dont think there IS something that has IEEE-1284c to USB . . .
thats why they have adapters . . .
KEEP THE CABLE YOU HAVE . . .
plug the parallel port (the one that would normally go into the comp) into a gender changer . . .
then plug a regular parallel to usb cable into the other end of the gender changer
plug the usb into your comp . . .
it works on my dads computer at work . . .
either that, or get a new printer . . .
they have em for $35 on newegg . . . . pretty good ones too
