Appendix J: Glossary
5 percent page: A page of text, used to provide a standard for the number of pages that can
be printed using one toner cartridge. So named because the toner covers five percent of the
page.
Adobe Type 1: One of the two common file formats for fonts (the other is TrueType).
Requires a PostScript printer or Adobe Type Manager for fonts to print correctly. Fonts can
be scaled to any size.
Adobe Type Manager: A program which allows you to use Adobe Type 1 format fonts on a
non-PostScript printer. Also improves the on-screen display of fonts.
AppleTalk: A network communication protocol for connecting Apple computers and
other devices to share information. When used with an EtherNet network interface, this is
known as EtherTalk.
Apply button: A button, usually found in a dialog box, which makes any changes specified
in the dialog box. Unlike the OK button it does not close the dialog box. See OK button,
Close button, and Cancel button.
AccuGray: A GCC software technology that enables truer halftone reproduction by coun-
teracting the effects of dot gain and by adjusting the print engine’s gray level response to a
1 to 1 correspondence.
all ports active: Technology that allows you to connect several computers and/or networks
to one printer. Each port is able to accept print jobs without affecting the others.
application (program): A program, such as Microsoft Word or PageMaker, used to
manipulate information.
baud: The speed at which data is transferred (bits/second).
bit: The smallest unit of computer information (a single binary digit).
bitmap: A representation of a shape in computer memory. It’s achieved by dealing with the
image area as a series of very small squares; if any square is more than 50 percent covered
by the image, that square is black (or, in color bitmaps, a color). Bitmaps typically are
made out of areas 1/72 or 1/96 of an inch square. Bitmap images cannot easily be enlarged
or reduced.
bitmap font: A font whose characters consist of the arrangement of bits into shapes. These
characters are used as screen fonts on computers that do not use scalable fonts, and they
tend to be jagged when printed on a high-resolution printer. Now largely replaced by
outline fonts.
