I want to connect my old HP Laserjet 4 to my PC running Windows 7 Pro. I know that the driver exits, but my question is about the cable. Clearly the computer end need a USB connection.
HOWEVER, what should be at the other end? The back of printer has two ports. One port says SERIAL and has the capactity for a male connector with 25 pins in two rows, one with 12 holes the other with 13 holes. The other says PARELLEL and has a linear "mortise and tendon" type port - see the attached files.
Which port should I use and is there a name or spec that I can use to identify the cable.
