3.7.3 STANDARD COMMUNICATION SEQUENCE OF BLUETOOTH INTERFACE
When Bluetooth interface is used, and if a connection between the host and the printer is
disconnected right after a data transmission, the transmitted data may not be properly sent to the
printer.
This should be avoided by performing one of the following methods on the application program.
(1) Disconnecting the Bluetooth connection between the host and the printer after the host
receives an end of job status from the printer and confirms the completion of the job.
(2) Waiting for the minimum of 100 msec. after a data transmission to the printer before
disconnecting the Bluetooth connection.
(3) Maintaining the Bluetooth connection while a series of print jobs are performed on the
application, and disconnecting the connection by key operations when exiting the print job.
As the completion of printer operations can be confirmed, method (1) or (3) is recommended.
