dpi

dpi
(Dots Per Inch) The measurement of the resolution of display and printing systems. A typical CRT screen provides 96 dpi, which provides 9,216 dots per square inch (96x96). Flat panel LCD displays from 110 to 200 dpi have also been developed, and in the summer of 2010, Apple introduced its Retina Display screen on the iPhone 4 with an impressive 326 dpi.

Double the DPI, Quadruple the Dots
As the dpi rate doubles, the number of dots within a square inch is quadrupled, because dpi deals with two dimensions. Thus, while 100 dpi produces 10,000 actual dots per square inch, 200 dpi produces 40,000 (see below). We have a long way to go to make the resolution on a screen as dense as a printer. A 1200 dpi printer produces 157 times as many dots of resolution as a typical 96 dpi screen. See dot pitch, resolution and E Ink.

                 Dots Per
      DPI        Square Inch
       96            9,216
      100           10,000
      200           40,000
      300           90,000
      600          360,000
     1200        1,440,000

Success checked with several manufacturers to find out which of their products are the most versatile, comparing the DPI ("Dots Per Inch," a measure of resolution; the higher the number, the more clear the image), pages per minute, and, of course, price of the following suggested laser printers--all of which come in under a thousand dollars.
DPI also will introduce a new model of its popular Flex Spray moulding sprayer.
