A:   Print quality is 300 dots per inch (DPI). Up to a point, printers with higher DPI produce clearer and more detailed output. A printer does not necessarily have a single DPI measurement; it is dependent on the print mode, which is usually influenced by driver settings. The range of DPI supported by a printer is most dependent on the print head technology it uses. Dpi is also referred to as pixels per inch.
   Pixels per inch (PPI) or pixel density is a measurement of the resolution of a computer display, related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. This measurement is often referred to as dots per inch, though that measurement more accurately refers to the resolution of a computer printer. PPI may also be used to describe the resolution of an image scanner or digital camera; in this context, it is synonymous with samples per inch.
