Why is my Epson serial interface printer printing garbled text? - KB Article - 130647




Compare and match the COM port settings

If your receipt printer is printing garbled text or random characters, then the COM port settings of your retail application or system settings do not match those of the receipt printer. To compare and match the COM port settings, perform the following steps:

  1. Run the receipt printer self-test.

    NOTENOTE:For more information on running the Epson receipt printer self test, refer to Dell Knowledge Base Article: "How do I print a self test on an Epson receipt printer?" Article ID: 132113.

  2. Click the Start button, point to Settings, and click Control Panel.
    The Control Panel window appears.
  3. Double-click the System icon.
    The System Properties window appears.
  4. Click the Hardware tab and click the Device Manager button.
    The Device Manager window appears.
  5. Click the plus (+) sign next to Ports (COM & LPT).
  6. Double-click Communication port (COMx).
    The Communications port (COMx) window appears.

    NOTENOTE:The COMx represents either COM1 or COM2, depending on which port the printer is plugged into.

  7. Click the Port Settings tab.
  8. Compare and match the COM port settings on the self-test printout to the COM port setting in the retail application or system settings.
