Generally speaking you do not need to worry about drivers when buying a popular brand name scanner, but it is worth understanding the basics to avoid potential confusion. The de facto standard which allows scanners and other optical devices to communicate with PCs is called TWAIN. The acronym purportedly stands for ‘technology without an interesting name’. Almost all scanners are TWAIN compatible, featuring driver software which allow them to work seamlessly with a wide range of related software. In recent years an alternative to TWAIN has emerged – ISIS (image and scanner interface specification). ISIS can be thought of an industrial strength driver specification designed to allow scanners to work more effectively with enterprise level applications. Manufacturers often provide both sets of drivers with their devices, but if in doubt just check with your supplier.
