1) When performing version-up of the firmware by using the file
transfer tool (File1PRN), the printer driver of the target model
must be installed in advance.
2) When performing version-up of the firmware by using the USB
I/F, take note of the following items.
Since the port for the file transfer tool (File2PRN) differs from
the port for the print mode, if the port for the print mode has
been already made, be careful not to mistake them. If the USB
port for the print mode has been made, it is advisable to delete
it in order to avoid confusion.
