font The complete set of a given size of type, including
characters, symbols, figures, punctuation marks,
ligatures, signs, and accents. To fully describe a font, you
must specify seven characteristics:
font, monospaced Also called fixed-pitch font and mono-font. Every
character, regardless or horizontal size, occupies the
same amount of font pattern space. All monospaced
fonts use specific pitch size settings. Monospaced fonts
are sometimes used when strict character alignment is
desired (tables, charts, spreadsheets, etc.).
font name see typeface.
font pattern A font pattern is the matrix of pixels which represents a
character, symbol, or image.
font, proportional A font in which the width of a character cell varies with
the width of the character. For example, "i" takes less
space to print than "m." Using proportional fonts
generally increases the readabilty of printed documents,
giving text a typeset appearance.
font weight The thickness of the lines making up a character. For
example, "bold" and "light" are different font weights.
font width The measurement of the width of a character cell in dots.
gateway A hardware device that translates data between two
incompatible networks.
gateway address The IP address of a gateway.
hammer The hammer spring with a hammer tip mounted onto it.
hammer spring The flat piece of metal, made of spring steel, which
supports and pushes the hammer tip.
hammer tip The small, round point, located near the end of the
hammer spring, which strikes the ribbon and leaves a dot
on the paper.
hex codes Based on a numeral system with a radix of 16.
host (computer) The computer that stores, processes, and sends data to
be printed, which communicates directly with the printer.
The term "host" specifies the controlling computer, since
modern printers are themselves microprocessor-
controlled computer systems.
1. typeface (Courier, Helvetica, Swiss, etc.)
2. spacing (proportional or monospaced)
3. type size (12 point, 14 point, etc.)
4. scale factor (character height/width ratio)
5. type style (Roman or italic)
6. character weight (bold, normal, etc.)
7. character proportion (normal, compressed,
expanded).
