I don't think you understand. There used to be a peripheral "card" which was just a short cable that plugged into the motherboard and led to a DB 25 on the back of the PC, then your parallel printer cable would just plug into that. The printer connector on the back of the M100 is the same as the one on the motherboards, so just get one of those adaptors and remove the bracket for mounting on the PC, and you've got your adaptor cable. Of course, I do like my Radio Shack original Model T to centronics parallel printer cable.
