Dpi

  This is an abbreviation for dots per inch, a measurement of print image resolution and quality. A larger number of dots allows for more detail, and therefore a higher resolution image. The average laser printer has a resolution of 300 x 300 dpi which means it can print 300 dots per inch horizontally and 300 dots per inch vertically, or 90,000 dots per square inch. A high-resolution, professional quality laser printer prints at 1200 dpi or 2400 dpi.
