Method
(3): Disconnecting the Bluetooth connection by key operations when exiting a series of print jobs.
This method improves the printing throughput of the application, as no procedures are required for
establishing Bluetooth connection each time a printing occurs, which takes about 1 to 3 seconds
(depending on the radio state.)
Also, maintaining the connection enables an error, such as a paper end or a paper jam, on the printer to
be detected by the application. However, when more than one host shares one printer at the same time,
this method is not applicable because the printer supports one-to-one connection only.
After a series of print jobs is terminated, Bluetooth connection is supposed to be disconnected at the
timing of returning to the main menu by key operations. In this case, a minimum of 100 msec. should be
given after all data are completely sent to the printer prior to the disconnection of Bluetooth connection.
