Basic Scanning
Since a line art or halftone image requires only 1 bit of computer memory for each pixel (dot), using either the Line Art or Black & White Halftone option will produce an image that takes up the least amount of space when saved to disk.

Resolution
In scanning, the term resolution refers to how detailed an image is, usually expressed in dots per inch (dpi). When you scan an image, you can adjust the resolution to improve the image, based on how you plan to output the image.
The best resolution setting for your image depends on the type of image you’re scanning and your final output device.
