I’m sure you’ve checked the software that came with your scanner, but they often come with a Scan to PDF option. My parents have an All-in-one that allows you to select Scan to… and then Choose PDF as File Type (I think those were the steps but my memory could be faulty). It would handle multiple pages and such. Our company’s scanners came with a free version of Acrobat Standard, which works really nice, but it’s quite pricey at $299 You could try this (cnet.download.com) but there didn’t really look like anything promising. If you’re willing to try open source you could try sourceforge.net (here) I’ve found a few gems there, but haven’t tried a Scan to PDF software. Good luck, and if you find something please post it on here. I’m always interested in finding more good free software.
