What Does 4800 X 1200 Dpi Mean?

The Business Dictionary defines dpi as the number of dots a printer or scanner can place or record in a one-inch space. A measurement of 4800 by 1200 dpi means that a printer rated as such can handle 4800 dots horizontally and 1200 dots vertically.

The higher the dpi rating of a device, the more details the device is capable of printing or capturing. The high level of detail obtained with a 4800 by 1200 dpi device allows viewers of the printed or captured image to magnify the image with less damage done to image quality than lower resolution printers or scanners.
