What does DPI mean?

Dots per inch (DPI) is unit used to describe the output quality or resolution of a printer. It describes the number of ink dots a printer is capable of producing in a linear one-inch space. Generally, the higher the dpi number, the sharper and more detailed the image can be depending on its size and image quality prior to printing. An inkjet printer uses tiny nozzles to spray its ink on the paper and most on the market is capable of producing 300dpi or more.
