A shading applied to a shape that you have drawn.
See monospacing.
A collection of characters that are designed to work in harmony together. A
font has several characteristics that identify it uniquely: character or symbol
set, spacing, pitch, height or point size, style, stroke weight and typeface.
Fonts can either be resident in the printer's ROM, installed on cartridge or
downloaded from your computer. You can either buy downloadable fonts
commercially or create your own. The word "font" is often wrongly used to
mean "typeface". A font is confined to a single height or point size whereas a
typeface is not.
A block of data that is downloaded to the printer as the first part of a
downloaded font. The font descriptor describes the characteristics that are
common to every character in the font, such as stroke weight, and contains
other relevant information.
The HP-GL and HP-GL/2 mode settings that are in effect when you enter HP-
GL and HP-GL/2 mode. You can restore the initial conditions using the IN;
command.
The default units of the HP-GL and HP-GL/2 coordinate system. Also
sometimes called plotter units.
The area on the page in which HP-GL and HP-GL/2 graphic images can
appear. Initially this is the same as the picture frame, but you can change the
size, position and aspect ratio of the graphics window using the IW
command.
A degree of continuous shading ranging from 0%, very light gray, to 100%,
black.
The area of the page on which it is physically possible to print using HP-GL
and HP-GL/2 graphics language commands. The hard clip limits are
determined by the size of the physical page and are equivalent to the LaserJet
mode printable area.
A method of shading using parallel lines.
The height in typographic points (1/72") of an unaccented capital letter in a
font.
Horizontal motion index. The horizontal distance that the print position
moves across the page when any single character is printed ( in a monospaced
font ), or when a space character is printed ( in a proportionally spaced font
). You can set the HMI using printer commands, however, when you alter
any font characteristic ( in effect, select a new font ) or switch between the
primary and secondary fonts, the HMI is reset to its default value based on
the newly selected font.
The original horizontal size of an imported HP-GL and HP-GL/2 image.
