DPI means Dots Per Inch
DPI is a unit that specifies the resolution (print quality) of printers, for example. One inch is about 2, 54cm, the greater the number of dots (dots) per inch, the higher the quality is. The word ' dot ' in combination with printer quickly leads to the old-fashioned dot-matrix printer, but also to photo scanning and monitors is often spoken of DPI. In Many cases it is better to speak of PPI (Pixels Per Inch), pixels are the points by which the images on computer or television are built up.
