I am working on catching up with the scanning and have completed 33 documents. I am scanning all docs in Multi-Tiff format (this allows multiple pages to be saved to one file), at 300 dpi, in 24-bit color. I am not sure if this is too much or too little color resolution, but the images are clear and bright and sometimes easier to read than the originals.
The files work equally well on my PC running XP and on the Mac computers at school. They open in Media Image Viewer on the PC and in Preview on the Mac. Both allow for printing.
