Nowhere on the package it states that it can only be used with scanners and printers. It is unusable for me because I bought it to use it with the x1541 cable. Yippee, I can't do that either because some *sshole in charge of such a hardware company thinks printerports are only to be used for petty office thingies
It`s a system friendly version interface for connecting old printers, that are still useful in many offices (like the dot matrix printers).
The x1541 cable, needs a specific s/w that calls IRQs, and a major
problem I had with a real centronics PeeCee mobo, was the OS! XP doesn`t allow direct h/w calls, so I needed a dual boot XP/Win98-MSDOS or a new dedicated Win98-MSDOS machine just for the C64. I gave up both solutions....
USB printers and scanners are dead cheap nowadays.
So are the old PCs with centronics and rs232 mobo ports ;-)
P.S. In case you make this work with a laptop, please give feedback on how you managed to do so ;-)
