Printronix L1024 Logical link, Macro, Non impact, Operating system, Parity check, Port, Protocol

logical link	The parameters that specify data transfer, data control, and/or data
	communication operations.
macro	A macro is a collection of control codes, escape sequences, and
	data whose execution can be initiated by using a single command.
	This information is downloaded into the printer.
MPP	Acronym for Maximum Print Position. Also known as line
	length.
NMI	Acronym for Non±Maskable Interrupt.
non impact	Printing which does not result from any mechanical impact onto
	the paper. Example: an electrophotographic printer.
OPC	The material of the OPC drum is an insulator when in the dark
	and is conductive when exposed to light.
operating system	A collection of programs that control the overall operation of a
	computer system.
parity (check)	Parity checking is the addition of a non±data bit to data, resulting
	in the number of ª1 bitº being either always even or always odd.
	Parity is used to detect transmission errors. Parity represents
	value in the check digit of the received or transmitted data.
PCB	Acronym for Printed Circuit Board. A PCB is an insulating board
	on which circuit paths have been printed or etched.
PCBA	Acronym for Printed Circuit Board Assembly.
port	A data channel used for receiving data from or transmitting data
	to one or more external devices.
protocol	The rules and conventions that govern communication between a
	printer and a host computer. A protocol includes codes for
	printing text and graphics and codes instructing the printer to
	perform special operations.
RAM	Acronym for Random Access Memory. Can be read from or
	written to at any time. RAM is volatile: Whatever is in RAM is
	lost when power is turned off.
