    For scanning software, I highly recommend VueScan:

    There are Linux, Windows and Mac versions, and it supports thousands of 
scanner models, including some very old ones. VueScan can also do CCITT G4 
compression, and directly create PDF files. If you but the pro version, 
updates are free. I've been using it for years.
