Where to buy the Star Micronics TSP100III LAN receipt printer

The Star Micronics TSP100III LAN receipt printer is available from the Shopify Hardware Store. This device is compatible with both iOS and Android.

  • the width is 3 1/8" (80mm)
  • the length does not exceed 230 feet (70m).

For an explanation of how to load the receipt printer, see the guide in the manufacturer's hardware manual.

Installation and setup

The TSP100III LAN receipt printer connects to your network using an Ethernet link interface.

Take a look at this video to see how quick and easy the setup procedure is:

Before you get started, make sure you have the cables you need.

Cable type Look for this connector Available from
Cash drawer cable
A cable for the cash drawer is included in the retail custom kit from Shopify. If you bought your cash drawer separately, your supplier should be able to sell you a cable.
Ethernet cable (for connecting to the router)
An Ethernet cable approximately 1m in length is included when you buy this printer from Shopify. If you buy it elsewhere, remember you'll need the Ethernet cable.


  1. Connect the receipt printer to the APG Vasario 320 series cash drawer using the cash drawer cable.

  2. Connect the receipt printer to the Ethernet port on your router. This makes the printer discoverable in the Shopify POS app.

After connecting your printer, don't forget to:

If your TSP100III LAN printer stops working

Your printer might not be working for several reasons.


  1. Check to see that your network cable is connected to your wireless router.

  2. Check to see that you are connected to the internet. Your printer requires an internet signal to run properly.

  3. Check to see that your printer appears on the Hardware screen in the Shopify POS app. If the printer is improperly connected, it will either not show up on the settings screen or it will appear as "Disconnected":

  4. Try turning your printer off/on. This will restart your printer and usually rectify any issue on the printer's end.

  5. To debug your printer, turn your printer off and press and hold the FEED button. While still holding the FEED button, turn the printer back on. Let the printer print off the firmware information and then let go of the feed button. The printer will try to connect to the internet and then continue to print off more diagnostic information. Take a look at the printed paper to see if any of the following issues match the text displayed:

    • The IP address under "Current IP Parameters Status" displays zeroes.

    The first thing to do is turn off the printer, wait five seconds, and turn it back on. Try the debug process again.

    If that doesn't work, confirm that you're connected to the LAN port of your router, and that your router is properly plugged in and working. Check out the printer setup video.

    Finally, if none of the above solutions worked, contact your internet provider. It could be a problem with your internet setup.

  • I see a "No Host Connection" message.

    This usually happens when you lose your internet connection or when your printer is not connected to your router properly. Check your internet signal and router cable.

If your printer is a long distance from your router

The network cable provided only extends to three feet. So if your router sits in the back of your store and your POS system sits in the front, the cable will not be able to reach. You can purchase a longer network cable and run it from the router to the printer.

If the ERROR indicator is blinking red

This is caused when there is no paper present in the printer. Open the printer, replace the paper, and close the lid. The ERROR indicator should turn off and the READY indicator should come on.

Paper jams

If you feed the paper into the receipt printer at an angle, it is likely you'll cause a paper jam. If this happens, turn off the printer, open it up, and try feeding the paper in again.

If you are trying to make your receipt narrower than the specified 3 inch width, make sure you use the divider provided. Don't fold the paper when you feed it into the printer.

Customize receipts

You can customize both the basic receipt layout and the transaction description.

Limitations when using the Star Micronics TSP100III LAN receipt printer
