Troubleshooting printer issues

USB devices plug directly into the compatible POS device. If you are using Square Stand, Square Register or Square Terminal, you can plug your USB accessory directly into the USB hub on the power cord. For Android devices, you’ll need to connect through a USB OTG (On-The-Go) adaptor. Check that your Android device supports USB OTG or USB Host mode. USB printers are hardwired to one POS device and only that POS can print to the USB printer.

Note: connecting a printer into an iOS device directly via a Lightning or USB-C is not supported.

Ethernet devices plug into your router or switch using an Ethernet cable. Once connected to your router via the Ethernet cable, your hardware accessories will connect to your POS device through the Wi-Fi connection. You won’t be able to use an Ethernet connection in Offline Mode.

Wi-Fi devices connect wirelessly to your router. Make sure your device and hardware accessories are connected to the same network via Wi-Fi or Ethernet. If they are on different networks, the connection will not be successful.

Bluetooth devices connect to your device wirelessly using the Bluetooth connection. Bluetooth works best in close proximity, and is not recommended for kitchen tickets. You’ll want to ensure that your device and hardware accessories are all within 10 ft of each other. Bluetooth printers can only be wirelessly connected to one POS device at a time and only that POS can print to the Bluetooth printer.

Printer profile settings are shared across all devices that are assigned to the profile. This can cause multiple copies to be printed if more than one printer profile has order tickets enabled, or if multiple Point of Sale devices have the same printer profile (with online orders enabled) assigned to a printer.

If you are receiving duplicates of your online order tickets from one or more printers, there may be an issue with your printer profile settings. Learn more about how to Troubleshoot Printing Duplicate Online Orders.

1. If you are using a Bluetooth printer, move your printer closer to your POS for stronger Bluetooth
2. If you use a Wi-Fi printer:
   • move the POS and printer closer to the router for a stronger Wi-Fi signal.
   • Check your local network setup and make sure your router has not moved or disconnected. A local area network (LAN) is a collection of devices connected together in one physical location.
3. Printer delays are expected if there are several devices connected to the same network using the same printer.
