6.2USING THE CENTRONICS (PARALLEL) INTERFACE
1.Is the IBM parallel printer cable connected securely to your parallel port
2.Is there more than one parallel interface port on your PC (LPT1, LPT2, etc.)? If so, make sure you are send- ing data out the correct port.
3.When you send the print job to the printer, and it does not respond, do you get an error message on your PC that says “Device Fault” or something similar?
This may mean that the computer doesn’t know the printer is there. Verify that:
a.Both ends of the cable are securely inserted into their respective connectors.
b The printer is ONLINE.
c.The cable is not defective. There are other things that can cause this error message on your com- puter, but at this stage, a defective cable may be one of the reasons.
