sheet. In reference to print media, a single, two-sided page of print media like paper or labels.
shielded twisted-pair (STP). A transmission medium of two twisted conductors with a foil or braided shield. Contrast
with
unshielded twisted pair
.
sizing. A process where paper is treated to give it resistance against penetration of liquids.
skew. Refers to the angle that the paper is taking while going through the forms path. This will cause the printing
lines to not be aligned properly.
software. Programs, procedures, rules, and associated documentation pertaining to the operation of a computer
system or word-processing system. Contrast with
hardware
.
special-application materials. Materials such as adhesive labels and preprinted paper on which the printer can
print.
stack lean. A measurable slope from the vertical of a stack of forms. Excessive stack lean can cause failures when
feeding paper.
storage. (1) The retention of data in a storage device. (2) In word processing, a unit into which recorded text can be
entered, in which it can be retained and processed, and from which it can be retrieved. (3) A device, or part of a
device, that can retain data.
STP. shielded twisted-pair.
system administrator. The person at a computer installation who designs, controls, and manages the use of the
computer system.
system programmer. A programmer who plans, generates, maintains, extends, and controls the use of an operating
system, with the aim of improving overall productivity of an installation. Contrast with

.
T
task. A basic unit of work to be accomplished by a device or an operator.
text. A graphic representation of information on an output medium. Text can consist of alphanumeric characters and
symbols arranged in paragraphs, tables, columns, and other shapes.
throughput. A measure of the amount of work performed by the printer over a period of time; for example, number
of jobs per day.
token ring. A network with a ring topology that passes tokens from one attaching device to another; for example, the
IBM Token-Ring Network.
transmission. The sending of a print data set to a printer.
twisted pair. A transmission medium that consists of two insulated electrical conductors twisted together to reduce
electrical noise. Contrast with
shielded twisted-pair
.
typeface. A specific type style, such as Courier or Gothic.
U
uniformly-spaced font. A font in which the character increment for each character is the same. Contrast with
proportionally-spaced font
.
unshielded twisted-pair (UTP). A transmission medium of two twisted conductors with no shield. Contrast with
shielded twisted pair
.
user. Anyone who requires the services of a computing system.
UTP. unshielded twisted-pair.
