ESC/P, short for Epson Standard Code for Printers and sometimes styled Escape/P, is a printer control language developed by Epson to control computer printers. It was mainly used in Epson's dot matrix printers, beginning with the MX-80 in 1980, as well as some of the company's inkjet printers. It is still widely used in many receipt thermal printers. During the era of dot matrix printers, it was also used by other manufacturers (e.g., NEC), sometimes in modified form. At the time, it was a popular mechanism to add formatting to printed text, and was widely supported in software.

The drum printer wasn't very big, being only in width, in height, in depth and weighed . It was created out of development work that Shinshu Seiki did for the Seiko Group when they became the official time-keepers for the 1964 Tokyo Olympic games and needed a machine that could print out times they gathered from their time-pieces.
