Why won't my product print serially from my computer?

  • There are a few possibilities:
    • Make sure your optional Epson serial interface card is set up properly.
      See Setting the conditions for the model C823051 Serial Interface Card

    • If you are using a straight through modem cable, change the cable to a null modem cable.
    • If you are already using a null modem cable, ensure that the settings for the printer's serial port 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 problems, try a different cable.
    • The problem may be related to your computer's serial port. Try using the printer on another computer to determine whether that is the case.
