You need to have the BHL2-Maintenance Printer driver and FILEDG32.exe (provided by Brother
Industries) on hand. Save them in an arbitrary folder in your PC.
Installing the BHL2-Maintenance Printer driver
To identify terminals connected via USB interface, a PC requires the corresponding virtual USB
devices to be implemented by driver/software. If you connect any number of machines 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 a 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 BHL2-Maintenance
Printer driver has been already installed to your PC according to this procedure, skip this
section.
NOTE: Before proceeding to the procedure given below, make sure that the BHL2-Maintenance
Printer driver is stored in your PC.
