A. Dot per inch
B. Dot per sq. inch
C. Dots printed per unit time
D. All of above
In printing, DPI (dots per inch) refers to the output resolution of a printer or imagesetter, and PPI (pixels per inch) refers to the input resolution of a photograph or image. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper.

Dot per inch DPI is the right answer
