Networking Issues

This section focuses primarily on network-related issues that can crop up between your WiFi Router, printer, and iPad connection.

My printer is not listed in Printer Setup.

The iPad may be on the wrong Wi-Fi network. On the iPad, open Settings and connect to the same network as the printer. If your iPad often switches itself to the wrong network, visit our iPad Settings Troubleshooting guide for help.

The READY light is blinking blue/green.

The printer is no longer connected to the network or is not receiving an IP address from the router.

If the READY light blinks steadily:

  1. Switch the printer OFF.
  2. Count to 5 and turn the printer back ON.

If the READY light double-blinks:

  1. Turn the printer's power OFF and check the physical connection between it and the router.
  2. Disconnect, then reconnect the ethernet cable to the printer / router.
  3. Switch the printer back ON.

If the issue persists beyond the above troubleshooting:

  1. Switch the printer OFF.
  2. Reboot the router (unplug it from the power source and plug it back in).
  3. Turn the printer back ON.

The READY light is solid blue/green light, but the printer is not working.

A brief interruption in your Wi-Fi network may have disconnected the printer from your iPad.

  1. Open the register Control Panel and tap 'Hardware Setup'.
  2. Select 'Printer Setup' and tap 'Refresh'.
  3. Tap the switch next to the name of your printer to toggle it on (GREEN).

    If you don’t see your printer, go to My printer is not listed in Printer Setup.

  4. Press 'Test Print' to check the connection.
  5. If the printer does not print, check if it receiving an IP address and repeat steps 1 - 4.
  6. If the printer still does not print, follow the steps below:
    • Power off the printer.
    • Reboot your router.
    • Power the printer back on.
    • Repeat steps 1 – 4.

Is my printer receiving an IP address?

Print a diagnostic receipt right from the printer. It’ll show you the Network Configuration and the current IP Address of the printer.

  1. Flip the power switch OFF.
  2. Press and hold the FEED button.
  3. While holding FEED, turn the printer back on.
  4. Once a receipt begins to print, release the FEED button.

    The second receipt will contain the Current IP Parameters Status and your printer’s IP Address.

"No Host Connection"

If a No Host Connection slip prints out, it means the printer is not connected to the network or is not receiving an IP address from the router.

If the READY light blinks steadily:

  1. Switch off the printer, count to 5, and turn it back on.

If the READY light double-blinks:

  1. Switch off the printer and check the physical connection between it and the router.
  2. Disconnect, then reconnect the ethernet cable to the printer / router.
  3. Switch the printer back on.

If the issue persists beyond the above troubleshooting:

  1. Switch the printer off.
  2. Reboot the router.
  3. Turn the printer back on.

Hardware Issues

Here you can find issues specific to printer hardware. This assumes your iPad is talking to the printer, but still not printing correctly.

Receipts print out blank.

The TSP100 is a thermal printer that uses special thermal receipt paper. Make sure you are not using regular paper bought elsewhere or included with a Ticket Printer.

Because the printer paper is thermal, information can only be printed on one side. If your receipts are blank, try removing the paper, flipping it over, and reprinting the receipt.

My printer works, but the cash drawer doesn't open.

The cash drawer is printer driven and requires no special setup other than connecting to your printer. Double check that the drawer is unlocked and the included cable is connected properly.

The ERROR light is solid red and the READY light is solid blue/green.

Either the printer cover is open or the paper roll is loaded improperly.

  1. Pull back the lever to open the cover.
  2. Remove the roll and reload it with the end of the roll feeding up from the bottom.
  3. Close the printer cover on the paper.

The ERROR light is blinking red and the READY light is off.

This means the printer has run out of paper or is going to run out soon.

Follow the instructions above to load a fresh roll or visit the ShopKeep Store to order more.

None of the printer’s lights are on.

The printer is not receiving power. Check that the power cable is connected securely to the back of the printer and to a wall outlet. If the problem persists, try using a different power outlet.
