Looking for simple Windows scan (multiple pages) to one PDF application? [closed]

This blog had the best documented suggestion of the simple and sweet iCopy.

I tried all the others and many more, and only this worked flawlessly. I already have used CutePDF free for a decade which acts as the "to pdf" converter after you get your pages all scanned in with iCopy.

Canon scanners come with a tool called CanoScan Toolbox. It can generate multi-page PDF files.

VueScan is the name of a tool that comes to my mind. It's not compatible with all scanners (most of them are supported; compatibility list here; for Windows, WIA scanners are supported). Unfortunately is not free. But it has the feature "Scanning to a multi-page PDF file".

Apparently (I did not try), Scan2PDF is free and can do it.
