Nastia,
Check out this Wiki article:

I've used an HP flatbed scanner. The table only holds the file path to the location where the scanned document is actually stored. If you use TIF format you can add annotations to the image. TIF also supports multiple pages to be stored in a single image file.
>Does anyone know how to scan documents, print date and incremental ID on the paper document and stamp image with the same date and Id? Any suggestion about hardware and software?
