+
+ Important for Chrome Users: +

If your printer doesn't connect, try these steps:

+
    +
  1. Make sure your printer is in pairing mode (LED should blink)
    2. +
  2. Keep the printer within 1-2 meters during pairing
    3. +
  3. If the printer was previously paired, unpair it from your device's Bluetooth settings first
    4. +
  4. Click "Scan for Devices" and select your printer from the list
    5. +
  5. When Chrome shows the pairing dialog, click Pair
    6. +
+
    -
  • 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
    • +
  • This feature requires Chrome 56+, Edge (Chromium), or Opera 43+ browser
  • The connection must be made over HTTPS (or localhost for testing)
  • Each device remembers its own printer configuration
    • +
  • Supported printers: RPP02, Epson TM-series, Star Micronics, and most ESC/POS thermal printers
