This is the driver for Brother printer/multifunction devices. It is a utility that converts the data to be printed to the specific fax/printer. The purpose of the printer driver is to allow programs to do printing without being aware of the implementation of each model. Whenever you print a document, the driver sends data to the printer with the correct commands. Windows will install generic printer drivers, however to get the most out of your printer, the Brother driver should be installed.
