Control Code
A control code is a type of PCL language command that initiates a
printer function, for example CR (Carriage Return), LF (Line Feed),
and FF (Form Feed).
Control Panel

to communicate with a device and allows the device to communicate
with an operator.
Current Active Position (CAP)
See CAP.
Cursor
Although the printer does not actually have a cursor, the cursor
position refers to the currently active printing position (like the blinking
underline character used on most computer terminals). The cursor
can be moved anywhere within the logical page using a combination
of horizontal and vertical cursor positioning commands and control
codes.
Decipoint
A decipoint is a unit of measurement that equals 1/720th of an inch.
Default
A value used instead of a programmatically selected value. A factory
default is a value programmed into the device at the factory; this value
is stored in read-only memory (ROM) and cannot be changed by a
user or operator. A user default is a default which is selectable via the
control panel.
Dot
The dot is the smallest printable unit. On HP LaserJet printers, one
dot can equal either 1/300th or 1/600 inch. The number of dots
printed per inch is referred to as the printer’s resolution.
