Engine
The part of a printer where the paper is physically processed and printed.
It is the body and internal components that house the controller.
EP-L Cartridge
The EP-L (electrophotographic) cartridge contains a photosensitive print
drum and a supply of toner. Because the drum is photosensitive, it must
be protected from exposure to light. The cartridge, which prints an average
of 3,500 pages, is replaceable.
ESP
Emulation Sensing Process is a function by which the controller interprets
a file’s data stream to determine its printer language and to select the
appropriate operating mode. ESP is the default operating mode.

command. It is usually not a printable character; instead, it is used as a
preface for printer command codes.

with an escape character.
