Troubleshoot Ethernet and Wi-Fi Interface Receipt Printers

  • Turn your device’s Wi-Fi off and then on again.
  • Turn your device completely off and then back on.
  • Turn your receipt printer off and unplug all cables. Plug all cables back in and turn the receipt printer on.
  • Make sure the receipt printer is fully plugged in and a roll of paper is in the printer.
  • Make sure that your Ethernet cable is connected to the right piece of hardware. You may need to switch the direction of the cable.
  • Turn your Wi-Fi router off and then on again.
  • Ensure the Wi-Fi router is working and that your device is connected.
  • Ensure that the Ethernet cable connecting the receipt printer to the Wi-Fi router is properly connected to the Ethernet port on each device.

If you are using the Star SP742 printer, you’ll need to double check that your printer is configured correctly. To reset the configuration:

  1. Disconnect all cables from your printer and ensure that the printer is powered off.
  2. Flip your printer over and locate your DIP switch cover (it’s located next to the product label and is kept closed by a single screw).
  3. Remove the cover to see the 8 DIP switches.
  4. Flip switch 4 and replace the cover.
  5. Plug all cables back in and power on your printer.

Often printer errors are due to connectivity or Wi-Fi issues. If you continue to have trouble, consult the manual for your wireless router manufacturer for troubleshooting tips.
