There is no need to print and then scan to create image files. Just use this printer driver instead to create the image files from your unprinted documents!

Other advantages are improved image quality, time saving, printer consumables saving and optimized resolution and file size.

To emphasise the latter point, with this printer driver you can usually get away with 75DPI at A4 size! When scanning a printed document you would usually need a minimum resolution of around 100DPI.
