Stands for “Dot Per Inch”, DPI is just a dimension of printer resolution showing exactly how many printer spots the printer may devote one-square inch, the larger the DPI the sharper the image.
Thus, a printer that’ll have 600 DPI is just a printer that may produce 600 x 600 per square inch or 360,000 dots per inch.
Monitors do not have dots, but do have pixels; the closely related concept for monitors and images is pixels per inch or PPI. Many resources, including the Android developer guide, use the terms DPI and PPI interchangeably.
