DPI

Definition:

DPI stands for dots per inch and is a common term used to describe the quality of a printer. If you can imagine that a printed character on a page is made up of many tiny dots, the more dots used to create that character, the better the resulting character will look. DPI describes how many of these dots can fit into one inch of a document. The higher the DPI the better the quality of the printed document.
