Receipt printers (USB, Bluetooth, Sunmi)

Print order invoices on 58mm or 80mm thermal printers from Settings, POS, and Orders.

For Owners, cashiers

Step-by-step

1Open Settings → Receipt printer. Pick 32 characters for 58mm (most Sunmi handhelds) or 42/48 for 80mm counters.
2Test print always works — choose the printer in the system dialog (Sunmi Inner Printer, USB, or a driver-installed printer).
3USB: Chrome or Edge on desktop → Connect USB → Send test. Works with Epson TM, TVS, Rongta, Xprinter and most ESC/POS 80mm printers.
4Bluetooth: Chrome or Edge → Connect Bluetooth and pick a BLE ESC/POS printer. Classic Bluetooth dongles are not supported in the browser.
5On POS or Orders after pay: Thermal 80mm, or Send to printer for the last connected USB/Bluetooth/Sunmi path.

• Sunmi built-in printers print invoices. Set 58mm, tap Test print or Send to printer, and pick Inner Printer if a dialog appears.
• Windows/macOS printer drivers are used via Test print / Reprint, not via Send to printer (that path is raw ESC/POS).
