Dot/Millimetre
Dots per millimetre (dot/mm) is a unit of digital image resolution expressing the number of dots per millimetre. It is used in high-resolution printing and scanning, where 1 dot/mm equals approximately 25.4 DPI. It is common in metric countries for specifying printer and scanner resolution.
Dot/Inch
Dots per inch (DPI) is the standard measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of one inch. It is used to describe the resolution of printers, scanners, and displays, with common values ranging from 72 DPI for screens to over 1200 DPI for high-quality printers.
