Method
(2): Waiting for the minimum of 100 msec. after a data transmission to the printer before
disconnecting the Bluetooth connection.
In the case that a method to confirm an end of job status, as described in Method (1), is not applicable, a
minimum of 100 msec. should be provided between the last data transmission and a disconnection of
Bluetooth connection to avoid an erroneous data transmission via Bluetooth.
The above mentioned 100 msec. is supposed to be counted up from the termination of a data
transmission via Bluetooth (radio wave).
Some hosts may store the transmission data of the application in the buffer in the driver, then send them
to the printer. In this case, care must be taken that there is time lag between the timing when the
application writes data into the output function and when the data transmission is actually completed.
Thus, the time which is required to complete a data transmission should be added to 100 msec.

* The printer status can also be confirmed with the following command:
• [ESC] WB [LF] [NUL]
Note that the contents of the status vary, which deserves special attention.
