  • Make sure your bluetooth printer is powered on and in pairing mode
    • +
  • Ensure bluetooth is enabled on your device
    • +
  • This feature requires Chrome, Edge, or Opera browser
    • +
  • The connection must be made over HTTPS (or localhost for testing)
    • +
  • Each device remembers its own printer configuration

+ + Bluetooth printer configuration is device-specific and stored locally on each device. + Each tablet or workstation can connect to a different bluetooth printer. +

+

+ Requirements: +

+
    +
  • Browser with Web Bluetooth API support (Chrome, Edge, or Opera)
    • +
  • HTTPS connection (or localhost for testing)
    • +
  • Bluetooth-enabled device
    • +
  • ESC/POS compatible thermal printer (e.g., RPP02)
    • +
+

+ Configuration: + Pair your bluetooth printer from within the POS session interface. +
