I have a workflow whereby I scan paper documents into searchable PDFs using a Fujitsu ScanSnap S500 document scanner. I am not a great fan of the bundled software, but it's dead simple to use: place a stack of paper at the top, push the green button and a searchable PDF comes out.
Now, I'd like to do something similar on Linux (Ubuntu 10.10). The scanner is supported out of the box.
I've looked at
XSanelooks powerful, but not really suitable as a workflow solution;
gscan2pdfis a bit closer to the "push the button, get the PDF" ideal, but still not 100% there.
Any other software you can recommend (free or otherwise)?
