Hi @Sizzle2042,
The Epson TM-m30, which I believe is the printer you are referring to is compatible with the Square System. It will be able to connect either via Ethernet, or Bluetooth depending on which version that you have.
To see more about compatible printers, feel free to check out this article here: https://squareup.com/help/au/en/article/6334-hardware-compatibility-by-device
