9-2. Dual Interface Type<Switching the Dual Interface Modes>
The dual interface enables the connection of an RS-232 interface and a USB interface, although
they cannot be connected concurrently.
The printer starts with the RS-232 interface at the time its power is turned ON.
Afterwards, it will switch automatically to the USB interface if a USB cable that is connected to
a computer is connected to the dual interface.
However, if a USB cable is connected to the printer while the power to the computer is OFF, the
printer will not switch automatically to the USB interface connection.
Once the printer has recognized a USB connection, it will continue to assume this connection
until its power is turned OFF, even if you disconnect the USB cable.
