Glossary
To further aid you in the understanding of the printer and computer peripherals, we have
created this glossary of terms. Some of the terms listed in this glossary appear in this
User's Manual, while others are commonly used computer terminology.
A
Application
A program that you use to perform a specific
task on your computer. These include programs
for word-processing or graphics creation.
ATM fonts

This font system was developed by Adobe Sys-
tems.
Attribute

tation, symbol set, spacing, pitch, point size,
style, stroke and typeface.

To make a copy of the original floppy diskette
or a file on the hard disk. Making a backup of
your disks or files ensures that you won't lose
data if the originals are lost or damaged.
Bit

mation that a computer can hold. The value of
a bit (which is either 1 or 0) represents a two-

Bitmapped character
A character in a font that's rendered as a bitmap
and drawn as a pixel pattern on the screen. See
also font and pixel.
Bitmapped font
A font in a single point size made up of bit-
mapped characters. Some fonts stored in the
computer system are bitmapped fonts.
Buffer
A "holding area" in the memory where infor-
mation can be stored by one program or device
and then read by another. For example, some
printers have built-in memory to store text that
comes from the computer faster than it can
printed. This memory, which frees the computer
for other work while the printer is printing is
called a printer buffer.
Button
An image on your screen which resembles a
push-button. You can click to designate, con-
firm or cancel an action.
Byte
A series of 8 bits that represent one character.
C
Cancel button
A button that appears in most dialog boxes which
you can use to cancel any command or option
you may have chosen.
Central processing unit (CPU)
The brain of the computer. It is the micropro-
cessor which performs the actual computations.
Centronics parallel port
A standard wiring configuration for parallel data
transmission. Centronics is often used as a syn-
onym for the parallel standard developed by
Centronics Inc.
Character set
The complete set of characters available in a
font.
Checkbox
A small box associated with an option in a dia-
log box or window. You can click on the check-
