Precautions for Using Multi-interface

This system has the following restrictions regarding connecting multiple host devices or interfaces to mC-Label3.

When using an iOS device as the host device via Bluetooth connection, do not use USB-C and Ethernet simultaneously.

Destination	Host device	Communication
Bluetooth	iOS	○
USB-C	Android, Windows, Mac, Linux	Unavailable simultaneously.
Ethernet	iOS, Android, Windows, Mac, Linux	Unavailable simultaneously.
< Bluetooth >	iOS, Android, Windows, Mac, Linux	<Unconnectable simultaneously>

When using an iOS device as the host device via Bluetooth connection, do not use USB-C and Ethernet simultaneously.

If you communicate with another interface while establishing communication from the iOS device connected via Bluetooth, a failure may occur, for example, print data may be erased or the communication may be disconnected.

When communication is disconnected, if the Auto Connection function of the printer is set to ON, turn the printer OFF once, then turn it ON again; Bluetooth connection is recovered. When the Auto Connection function is set to OFF, perform Bluetooth pairing again.
