Notes for using Bluetooth
When you are connecting the machine via Bluetooth, the printer may not start to receive the
data immediately after the port is opened. We advise to wait for an interval of 500 msec before
sending the print data to the machine.
If you normally close and re-open the Bluetooth port between prints, we would again advise to
leave 500 msec between the port being closed and re-opened.
Also, once you have sent the print data, and the printing process has begun, do not close the
port. Please ensure 32 bytes of data has been received by the printer, and then close the port.
