1.1 Rewriting the firmware (Main Program)
1.1.1 Installing the maintenance printer driver
To identify terminals connected via USB interface, the PC requires the corresponding virtual
USB devices to be implemented by driver. If you connect any number of the machine to your
PC, therefore, the same number of virtual USB devices will be automatically configured on
your PC. To prevent virtual USB devices from being configured limitlessly, use the unique
driver installation procedure described below that enables your PC to identify terminals via
single virtual USB device.
Once this installation procedure is carried out for the PC, no more driver installation will be
required for that PC to identify machines. If BHL2 Maintenance Driver is already installed to
your PC, fully uninstall the BHL2 Maintenance Driver before installing Brother Maintenance
USB Printer Driver.
