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.

This is a normal DB25 parallel connector on the PC, the cable ends in a 36 pin centronics connector.   I have given away or donated to e-waste all the ones I had.  Try a flea market or garage sales.

See this post on connecting a Laserjet 4 via USB. You will need a USB to Centronics adapter and not all adapters work. Good Luck
