[Note]
1. When the link with Bluetooth is lost (out of area), disconnect from the printer after the supervision timeout time.
When the link between the host is lost, the printer request disconnection (DISCONNECT) after the supervision timeout time (default=20 sec (changeable from the host))
has passed.
2. It takes about 5 sec from the printer power on, installed Bluetooth module starting up to be the status of (1). Before the status of (1), it may not be connected.
3. Make sure to check the printer status by sending status request command (ENQ) before sending any print data because the printer cannot print during printer error.
