Networking Issues

This section focuses on network related issues between the WiFi router, printer, and iOS device connection.

What’s the IP address of my Ambur device?

Each device in a network has an IP (Internet Protocol) address, which is an assigned number that facilitates communication between devices over a network. Follow these steps to find your network’s IP address.

  1. Open the Settings app on the iOS device and choose 'Wi-Fi'.
  2. Tap the name of the network.

    The network’s IP address is listed in the network details.

Is my iOS device connected to the right network?

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

  1. Turn OFF the printer.
  2. Hold down the FEED button.
  3. While continuing to hold the FEED button, turn the printer back ON.
  4. Once the printer begins to print, let go of the FEED button.

    Two receipts print, but only the second is necessary.

  5. On the second receipt, locate 'Current IP Parameters Status' at the bottom.
  6. Compare the printer’s IP address to the Ambur device’s IP

    The first three groups of numbers for each IP address should match. If not, the device is connected to the wrong network.

The printer is set up, has a solid blue / green READY light, but fails to print.

The iOS device may not be connected to the correct WiFi network or the wrong printer was selected.

  1. Visit the iOS device's Settings app.
  2. Tap 'Wi-Fi' and verify that it's connected to the right network.
  3. In the Ambur app, check the printer status to make sure it's still online and the correct printer is selected. Follow the steps below to do so.
      Tap ‘Management’.
      Select ‘Printers’.
      Choose the printer you’d like to check the status of.
      Tap the Menu button.
      Select ‘Check Printer Status’.
Check the printer status.

"Printer Error" is displayed on the device and the printer's READY light is blinking blue / green.

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 back on.

If the READY light double-blinks:

  1. Switch OFF the printer and check the physical connection between it and the router.
  2. Reconnect the ethernet cable to the printer and router.
  3. Switch the printer back ON.

If the issue persists beyond the above troubleshooting:

  1. Switch the printer OFF.
  2. Turn router OFF, wait a few moments, then turn back ON.
  3. Turn the printer back ON.
  4. Check the IP address again.

    If you receive ‘Did Not Obtain’ or ‘’ instead of an IP address, power off all devices (iOS devices, printer, router, and possible extender) again and reboot each device one at a time. Wait a few moments for each device to power back on before checking the connections again.

"No Host Connection" prints out and the READY light is blinking blue / green.

The printer is not connected to the network or is not receiving an IP address from the router.
Follow the steps above to troubleshoot and resolve this issue.

Hardware Issues

Here, we’ll take a look at issues specific to the printer hardware. These are assuming the iOS devices are communicating with the printer, but still not printing correctly.

Receipts are printing out blank.

The TSP100 uses special thermal paper and information can only print on one side of it.

  1. Scratch both sides of the paper with a fingernail.

    Thermal paper has a glossy side and changes color when scratched.

  2. If the paper is thermal, follow the instructions below to properly load the roll.

The printer has a solid red ERROR light and isn't printing.

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

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

The printer’s ERROR light is blinking red, the READY light is solid blue / green, and nothing prints.

This means the printer has run out of paper or is going to run out soon. Follow the instructions directly above to load a fresh roll correctly.

The printer's power switch is on, but none of the status lights are lit.

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