Convert scans to PDF automatically, with WinScan2PDF
WinScan2PDF is a free, very small (~40k), and portable application that will help you scan your documents and save them in PDF format, using any type of scanner you may have.
WinScan2PDF is nice if you don’t need a PDF printer driver or some other complex program.
WinScan2PDF can also handle multiple pages (scan many pages before creating the PDF file.)
