GLOSSARY
offline Devices not under the active control of a central processing unit. For
example, a computer makes output to a magnetic tape. The tape is
then used by an offline printing system to produce printed data.
Offline operations are much slower than online operations. Refer to
online.
offset To place pages currently being printed in slightly different positions
from previous pages.
offset printing A widely-used method of commercial and corporate printing, where
ink is picked up by a metal or paper plate, passed to an offset drum,
and then passed to the paper.
online Devices under the direct control of a central processing unit, e.g., a
printing system in interactive communication with a mainframe. Refer
to offline.
operating system Basic host- 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.
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).
page orientation Direction in which data is printed on a report. Refer to landscape
page orientation and portrait page orientation.
parsing To read or interpret a command; build up a parameter list from
information within a command.
PC Personal computer. Family of computers that most commonly run a
version of DOS.
Page Description Language (PDL) Page description language used to describe the printing of jobs to a
laser printing system. PDL describes the input (type, format,
characteristics), performs the processing functions (logical
processing), and describes the output (type, format, font selection,
accounting options) of a print job.
peripheral Device used with a computer or workstation, usually for input or
output. Printers, modems, and the IPS/NPS cartridge tape drives are
examples of peripherals.
platform Combination of hardware and operating system software.
portrait page orientation Orientation of print lines or the top of an illustration parallel to the
short edge of the paper.
