The Square app is compatible with a wide variety of third-party hardware accessories. Below, you’ll find a list of supported accessories for Android devices, where to purchase them, and information on getting set up.
Note: Bluetooth hardware accessories aren’t currently supported with Android devices.
USB Receipt Printers
USB receipt printers can be used to print customer receipts, order tickets, and order ticket stubs. USB printers connect to Android devices via a USB OTG (On-The-Go) adaptor. Make sure your device supports USB OTG or USB Host mode.
Note: TSP100 series printers used with the Square app require 80mm receipt paper.
Receipt Printers with Ethernet Interface
Ethernet receipt printers can be used to print customer receipts, order tickets, and order ticket stubs. Ethernet interface printers are best for stationary use, and aren’t designed to be mobile.
The Ethernet printers compatible with the app are thermal printers. They require heat-sensitive paper and won’t work with non-thermal receipt paper. These types of printers aren’t ideal for kitchens or high-temperature working areas.

Impact Kitchen Ticket Printer with Ethernet Interface
Impact printers only print order tickets for a kitchen. They’re not affected by heat and can withstand warm environments. They require heat-sensitive paper and won’t work with non-thermal, receipt printer paper.
