5.3.3 Bluetooth Connection
The devices, such as hand-held device, laptop and other handheld data terminal with
Bluetooth can drive AH58F to print by Bluetooth. AH58F is compatible with Bluetooth4.0
standard(4.0 includes BR/EDR and BLE). Power class is CLASS 2, effective
communication distance is 10m. The Bluetooth of the printer belongs to the slave device.
The initial name of the printer is AH58F
, the initial password is ‘1234’.
The mobile printer need to pair with host device Bluetooth first, the pairing initiated by
the master device before AH58F working. The pairing is as follows:
1. Power on the printer
2. Host device search external Bluetooth device
3. If there are many external Bluetooth device, choose AH58F
4. Input password: 1234
