Auto reconnection
With iOS device Bluetooth communication, a connection between a paired iOS device
and the printer is not automatically restored after it is lost. However, when auto recon-
nection is enabled, the printer tries to reconnect with an iOS device after two-way com-
munication is enabled and automatically restores the connection.
CAUTION
This function is enabled when shipped from the factory. (MSW13-6)
Auto reconnection can take some time to connect when the host is not an iOS device.
 Even if the partner device is an iOS device, the conditions below can interfere with the auto
reconnection function.
Ÿ When you want Bluetooth communication to cut off after printing is complete
Ÿ When there are multiple iOS devices printing on the same printer
Under such conditions, disable auto reconnection.
Enabling and disabling auto reconnect
