no one spoke of printer cables. Serial connectors are 9 pin, parallel cables are 25 pin. while old style printer cables use 25 pin as well, there is no, or not to my personal experience a 9 pin connector at all for those printer cables. as a side note allot of external speech synthesizer hardware used 25 pin connectors. and lpt port allocations as well.
I thought you mentioned a parallel port in your first message and in a reply to me you said "connects via serial port on the computer, to a parallel port on the back of the reading edge". I suspect you got confused because while printer ports, on computers, are 25 pin, serial ports, while currently 9 pin, used to be 25 pin. I then mentioned gender, so you could tell one from the other by touch.
