Networking Issues

This section focuses on networking related issues between the printer, Wi-Fi router, and iOS device.

What is my Ambur device’s IP address?

Each device on a network has its own IP address, an assigned number that facilitates communication between devices. Follow these steps to find the IP address of your iOS device running Ambur.

  1. Open the Settings app on the iOS device.
  2. Select 'Wi-Fi' and tap the network with the blue checkmark.

Is my iOS device connected to the right network?

Compare your printer’s IP address to the iOS device’s IP address to determine if the iOS device is connected to the correct network.

  1. Turn the printer off.
  2. Hold down the FEED button.
  3. While continuing to hold FEED, turn the printer back on.
  4. Once a receipt begins to print, release the FEED button.

    A second receipt containing the printer’s IP address will automatically print.

  5. Compare the IP address from the second receipt with your Ambur device's IP address.

    The first 3 groups of numbers in each IP must match. If they do not, it means the iOS device is connected to the wrong network.

My printer has a solid READY light, but it fails to print.

The iOS device may not be connected to the correct WiFi network or printer may not be properly set up.

  1. Make sure the iOS device running Ambur is connected to the right Wi-Fi network.

    If it is not, reconnect it to the correct network.

  2. Make sure the printer's IP address is entered correctly in Ambur.
    • Tap ‘Management’ and select ‘Printers’.
    • Choose your receipt printer from the list.
    • Check if the IP address entered matches the printer’s actual IP address.

    • Choose your receipt printer from the list.

"Printer error. Couldn't connect to printer."

This error appears in Ambur if the printer disconnects from the network or it is not receiving an IP address from the router.

Follow the steps below to troubleshoot this issue. After each step, check if the problem is resolved.

  1. Make sure the iOS device running Ambur is connected to the correct Wi-Fi network.

    If it is not, reconnect it to the correct Wi-Fi network.

  2. Power cycle the printer.

    Switch the printer OFF, count to 10, and turn the printer back on.

  3. Disconnect and reconnect the printer.
    • Switch the printer off and unplug its ethernet cable from the printer and router.
    • Plug the ethernet cable back into the printer and router and turn the printer on.
  4. Try using a different ethernet cable.
    • Unplug the ethernet cable from the printer and router. Then, connect a new cable.
    • Flip the printer’s power switch to turn it off, wait 10 seconds, and turn the printer back on.
  5. Restart your router.
    • Unplug the router from power, wait about 10 seconds, and plug it back in.
    • Once your router is back online, turn the printer off, wait about 10 seconds, and turn it back on.

"No Host Connection"

If a No Host Connection slip prints out, the printer is either not connected to the network or not receiving an IP address from the router. Follow the steps above to troubleshoot and resolve this issue.

Hardware Issues

Here we’ll look at issues specific to the printer hardware. These issues assume your iOS device is communicating with the printer, but still not printing correctly.

Receipts print out blank.

The TSP100 requires thermal receipt paper. If you loaded regular paper, receipts will print out blank.

  1. Push the lever to open the back cover.
  2. Check to see if you are using thermal receipt paper.

    Thermal paper is shinier on one side and turns black when scratched.

  3. Make sure the paper is installed correctly.

    Thermal paper only prints on one side. The paper must be loaded so it feeds up from the bottom of the roll.

Not using thermal receipt paper? Contact us to purchase some.

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 incorrectly.

  1. Push the lever back 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.

  1. Follow the instructions above to load a fresh roll.

    Contact us if you need to order more thermal printer paper.

None of the printer’s lights are on.

This indicates that the printer is either turned off or not receiving power.

  1. Toggle the power switch to make sure the printer is not turned off.
  2. Unplug the power cable from the printer, then plug it securely back in.
  3. Unplug the printer from its power outlet and plug it into a different outlet.

    Make sure to connect the cable to an outlet you know for sure is working.
