Troubleshooting
1. Ensure the printer is powered on and in pairing mode
2. On Android: enable Location (required for Bluetooth scan)
3. Place the printer within 10 m and tap Scan again
4. Devices with no name show as "Unknown Device"—you can still connect
5. D320FAX (d320fax_295c): use Bluetooth mode, tap Scan—shows paired + nearby devices, no filtering
6. Restart the printer or app if not visible
