Why Does My POS Printer Keep Going Offline?

Why Does My POS Printer Keep Going Offline?

During the busy holiday season, proper functioning of POS equipment is more crucial than ever, especially for retail establishments. And when there are issues-- such as your POS printer disconnecting from the internet-- it’s imperative to get the issue resolved as soon as possible.

We’re here to help! Read on to find out why your printer may be disconnecting from the internet, and what you can do about it. Please keep in mind that it can take about thirty seconds for a printer’s status to update after trying one of these fixes or editing your printer’s settings.


How to Know Your Printer is Offline

Certain POS Printers, such as the Epson TM-M30, have the capability to connect to the internet via an Ethernet connection or WI-FI (depending on the interface card you purchased). These printers usually have indicator lights to let you know whether or not they are connected to the internet. Please see the photos below so that you recognize the symbols associated with WI-FI and Ethernet.


WI-FI and Ethernet Symbols


If the corresponding symbol is lit up with a solid light on the TM-M30, the connection is established. If the symbol is flashing, that connection type is failing (i.e. the IP address has not been acquired). If it is not lit at all, it means that there is no internet connection.


Common Reasons Your Printer Might Be Offline

Your POS Printer may be offline under certain normal circumstances. Some common occasions your printer may disconnect from the internet are when the machine is powering on or off, or when the printer is in a standby state. Another occasion could be when your printer is performing a self test, or when you are changing printer settings.


WI-FI Connection Issue Fixes

Some modern POS printers are able to connect to the internet via a wireless connection; however, these printers can sometimes malfunction. Here are some fixes you can try:

  1. Turn off the printer by holding down the power button, wait ten seconds, and turn back on. If this doesn’t work, unplug the printer and plug it back in to reboot.
  2. Ensure the WI-FI password has not been changed and has been entered correctly.
  3. Try connecting to the wireless router with a different electronic device to ensure it is working properly.
  4. Try moving the printer closer to the router to see if you are able to connect.
  5. Avoid placing your printer near a microwave, cordless phone, or any large metal objects/metal furniture.

If you are still unable to re-connect to WI-FI, another option would be to plug your printer directly into the router using an Ethernet cable. (Check back on January 12 for our next blog post to learn how to use an Ethernet cable with a printer that does not have an Ethernet port!

        Ethernet Connection Issue Fixes

        1. As with WI-FI troubleshooting, turn off the printer by holding down the power button, wait ten seconds, and turn back on. If this doesn’t work, unplug the printer and plug it back in to reboot.
        2. Look at the Ethernet port indicator lights. On certain printer models, if the lights are both green, your printer is connected to the internet. If one light is orange, you could have a cabling issue. Try to use an alternate Ethernet cable and be sure it is securely plugged into your router.
