PPM or
Page Per Minute, is a common method of measuring the output of a
printer, as it determines the speed a printer is capable of printing. PPM between different printers cannot be compared on a one-to-one ratio, as you can expect a different PPM number between different types of printers (
lasers or
inkjets) as well as different PPM numbers between color and black & white print jobs, and the
resolution of the image or text being printed. Most printer manufactures will specify the maximum page per minute you can expect to achieve with a specific printer model.
