PPI (pixels per inch) is the input resolution of an image or photograph, and DPI (dots per inch) is the output resolution of a printer or imagesetter. A measurement of the output quality of a printer’s resolution is called DPI (Dots Per Inch). It shows how many ink dots the printer can fit into an inch square of space. The image is less sharp and vice versa the lower the DPI.

Answer – The output quality of a printer is measured by dots per inch.
The term print quality describes how well a printer produces a hard copy or printout. The accuracy of the source material’s reproduction is affected by the type and quality of paper used as well as, of course, by the printer’s specifications, including the dots per inch (DPI), the print-head capability, and the kind and quality of ink or toner used, is what ultimately determines the quality level.
The driver of the printer and the ink or toner used are two other parameters that affect print quality in addition to DPI. For the printer to know where to place each dot on the page and what color to use, the printer driver converts the source image into a set of instructions. The output would unquestionably be incorrect if the instructions were inaccurate. Printers occasionally produce artifacts in the printed image due to flawed printer driver codes.
Summary:
The Output Quality of a Printer is Measured by
The output quality of a printer is measured by dots per inch. When an image is reproduced as a true physical object, such as when printed onto paper, the term DPI refers to the physical dot density of the image.
