First thing is to make sure that you can scan normally, making sure that your twain drivers are set up, you can scan to a file, etc. If nothing else, you can scan to a file and insert it into your pdf.
I've been using the scanner successfully for months. What I was hoping for is the ability to zoom in on antique postcards and thought that if "PDF'd" from an original I might lose less clarity on a zoom as opposed to scanning to some kind of file and then converting.
If I were to save to a file, what format would be best?
