4.2.3 The Scan Parameters Option
 Resolution:
The resolution is measured in pixels per inch (ppi) (sometimes referred to as dots per inch or dpi). Higher
resolutions result in more detail in the scan, slower scanning and in general, greater file sizes. For example,
an A4 size color image scanned at 300 dpi with color mode consumes approximately 25 MB of disk space.
When OCR (Optical Character Recognition) is to be performed on a scan, 300dpi should be used for most
languages except Asian languages. For Asian languages, 400 dpi is recommended.
Move the slider to choose your ideal resolution. The default value is 300 dpi. Available resolutions are 75,
100, 150, 200, 300, 400 and 600. (Options vary based on type of scanner.)
