The DPI control is a physical switch on the top, bottom or side of your mouse. Press or slide the switch to adjust your mouse's sensitivity. Your mouse's LCD then displays the DPI setting, or you see a message on the monitor informing you of the DPI change.
For Printers and scanners, the individual points of color are often called 'dots' rather than pixels, but the concept remains the same as the stadium. Because the output of a printer is paper which is usually measured in inches, the term DPI or Dots Per Inch is used to communicate the scale or physical size of each pixel. Just as it takes many people seated in a grid to display a card stunt at the stadium, a printer must place dots of color on paper to create a photo.
