Great question. All Epson thermal printers are supported by our service.
Let me explain why, the service works by installing an app on the local machine connected to the printer, we support Windows, MacOS and Linux as outlined in Step 3 of our quick start guide: https://getbizprint.com/quick-start-guide/#step-3.
We refer to this as the printer host once the app is installed and connected to the cloud service. As a result, the printer host can use all OS functionalities for printing and connect to all printer models. As long as the Epson thermal printer can be installed on the local machine you use for the service it will be supported.
Note: The “local machine” printer host running the app can be a small, cheap, low-power device, for example a Raspberry Pi or miniPC.
