Scanners like printers have used a standard driver for many many years. Both on Mac and Windows. Its part of the Universal aspect of the USB spec. Macs have been able to directly detect and use scanners without a specific driver from the manufacturer for a long, long time.
There is no requirement to install a specific driver or even the Scanners software for a scanner at this point in time.
Drivers and extra software only serve to enable specific features of the scanner that may not be covered in the generic built in scanner interface driver on Mac or Windows.
Its always best to attempt to use the scanner directly without any added software and only install drivers and software if extra features are required.
