< Installing the maintenance driver >
To identify machines connected via USB direct interface, the PC requires the
corresponding driver for the virtual USB device. If you connect any number of machines to
your PC, the same number of virtual USB devices will be automatically configured on your
PC. To prevent many virtual USB devices from being configured, use the unique driver
installation procedure described below that enables your PC to identify terminals via one
single virtual USB device.
Note:
- Once this installation procedure is carried out for a PC, no more driver/software installation
will be required for that PC to identify machines. If the Brother Maintenance USB Printer
driver has been already installed to your PC according to this procedure, skip this section.
- Before proceeding to the procedure given below, make sure that the Brother Maintenance
