I don't want to have to interact back and forth between my computer and my scanner to scan documents. My scanner has buttons on it, I want them to work. There are very, very few scanners that will scan directly to your computer or a network drive using only the buttons on the scanner that don't require a Windows or Mac PC running their network scan server software. And the companies that do publish their drivers and software.to Linux don't ever seem to include the scan service component, so you have to drive the scanning operation from your computer instead of the scanner's buttons.
