Using LCDS Print Description Language

metacode

Same as “native mode.” Method of speaking to and controlling

the image generator. These controls are used by the character

dispatcher to generate scan line information. This information is

sent in the form of character specifications to the image

generator, which uses it to compose the bit stream that

modulates the laser.

MHz

megahertz. 1. Unit of cycling speed (one million cycles per

second) for an electromagnetic wave (in particular, a radio

wave). 2. Sending and receiving stations of a radio wave

transmission must be tuned in to the same unit of megahertz.

MICR

Magnetic Ink Character Recognition. MICR allows a computer to

read characters printed in special metallic ink by scanning the

shapes of their magnetic fields. MICR fields are often imprinted

on bank checks before processing.

module

Cohesive unit within a program. It is consistent in its level and

identifiable in terms of loading or with other units.

MTU

magnetic tape unit (refers to the 9-track magnetic tape drive;

also referred to as “magnetic tape drive”)

nonimpact printer

Printer that forms characters without any strikes of a key or

element against the paper.

object file

Source file converted into machine language (binary code).

OCR

optical character recognition

offset

To place pages currently being printed in slightly different

positions from previous pages.

OLI

online interface

operating system

Basic host- or LPS-resident controlling program that governs the

operations of a computer, such as job entry, input/output, and

data management. The operating system is always running

when the computer is active. Unlike other types of programs, it

does not run to an end point and stop. The operating system of a

Xerox LPS is referred to as the operating system software

(OSS).

orientation

1. In reference to image area, orientation describes whether the

printed lines are parallel to the long edge of the paper or the

short edge of the paper. 2. Choice of printing portrait (vertically)

or landscape (horizontally).

origin

In reference to image area, this is the upper left corner of a

sheet.
