Recently my Linux crashed and I was forced to move to Windows and from now on work on that and was really dissapointed to find that our scanner's software wasn't commercially licensed (and that's the scanner's own scanning application). Anyway, so I went searching for something and after a maybe two or so days of searching, HE lead me to Documalis. It's a France based (from the domain on the e-mail and the French website) company that created a Freeware scanner application. In it's downloaded state, it has a 10 page limit per session, but for a small fee you can unlock it.

But what makes this program incredible is it's interface, it's ability to join PDF's, output to images and add pages to PDF's (unprotected ones of course).

It is a brilliant app and I really really recommend it if you have any scanning work that you need for commercial use. This is it!

To download it, you can find the link here:

(in English and it is the download section)

PS, it doesn't have a 'Save' button, you save by clicking 'Validate' in the corner after you've scanned; it opens the Save dialog; also kinda cool.

If you have any questions, don't hesitate to contact them. They have incredible service (it's why I'm recommending them, as well as their software rocks!!).
