The term PRINTER MEASURES can be solved by the three-letter acronym EMS, which stands for 'Electrostatic Measurement System.' EMS is a type of printer measurement system that uses electrostatic fields to measure the performance of a printer. It is used to measure the accuracy of a printer's output, such as the resolution and color accuracy. EMS is also used to measure the speed of a printer, as well as its ability to handle large volumes of printing.
