Resolution determines how many pixels, or dots,
are used for scanning and reproducing an image.

As the resolution value increases, the scanner

reads and reproduces the image in finer detail.

You might hear resolution described in terms of

dots per inch (dpi), or pixels per inch (ppi).

The best resolution setting really depends on the
type of image you are scanning and the printing
method. The table below shows optimum
scanning resolutions for most needs.
