Why won't my product print serially from my computer?
- Make sure you have your optional serial interface card set up properly. If you are using a straight through modem cable, change the cable to a null modem cable (pins 2 and 3 are reversed). If you are already using a null modem cable, ensure that the Default Settings for the serial port on the printer match the settings on your computer. There is always the possibility of a loose connection or a bad cable. Disconnect and reconnect the cable on the PC and the printer and try printing again. If you are still experiencing difficulty, try a different cable or take the printer to another computer to see if the computer's port is malfunctioning.
