J-4
halftone cell: A pattern of printed dots; each dot can be turned on or off in order to repre-
sent different percentages of gray.
high-quality fonts: Outline fonts that are shipped with the printer or purchased from your
dealer. On the Macintosh, screen fonts are used to create your documents and the printer
replaces them with high-quality fonts during the printing process. See outline fonts.
Installer: An application that installs the software.
interface: The point at which two devices are physically connected, enabling them to
communicate. Printers have a number of sockets; you plug a connector into these sockets
depending on whether you’re communicating with the printer by network, parallel, or
serial port.
jaggies: A slang term for the effect when some fonts and images print with jagged (rather
than smooth) edges. This usually happens if you attempt to print a resized bitmapped
image or font, or if you have screen fonts but not printer fonts on the Macintosh.
lpi: (lines per inch) A measure of the frequency of a halftone screen (usually between 53
and 200). Lpi refers to the lines of halftone spots that make up the screen. Higher lpi
usually means a better-quality image.
LocalTalk cable system: Apple’s network cable system used to support an AppleTalk
network system.
megabyte: A unit of measurement equal to 1024 kilobytes, or 1,048,576 bytes.
NEST (Novell Embedded Systems Technology): A feature of many GCC printers, which
can be used on Novell networks. Normally, a Novell network requires you to dedicate a
computer as a print server; NEST allows the printer itself to fill that function.
NetWare: Network software from Novell that enables computers to communicate with
other computers and peripherals such as printers.
network: A group of computers and peripheral devices, such as printers, that are intercon-
nected so they can communicate with each other. A network also includes the hardware,
such as cables that connect the devices, and the software that allows them to communicate.
OK button: A button, often found in a dialog box, which closes the dialog box and makes
any changes that were specified. See Cancel button, Close button, and Apply button.
on-screen preview: A representation of a vector image as a screen bitmap. This allows you
to edit the image in graphics programs; your changes are also applied to the vector image.
Windows previews are BMP format; Macintoshes are PICT. If you transfer a vector image
from Mac to PC or vice versa, you’ll usually lose the on-screen preview.
