* WHQL (Windows Hardware Quality Labs) is a process of testing 3rd party device drivers by Microsoft to ensure that they can efficiently run within their Operating Systems. Any Brother device driver which carries the WHQL or Microsoft Certified mark has undergone these tests and has been approved by Microsoft.
A device driver is a small piece of software that tells the operating system and other software how to communicate with a piece of hardware. For example, all printers come accompanied with drivers to install that tell the operating system exactly how to print information on the page. Sound card drivers tell your software exactly how to translate data into audio signals that the card can output to a set of speakers.
