The position from which printing of the next character or graphic object will
begin, providing that no operations that change the print position are
performed in the interim.
Fonts intended for high quality typographic output use a method of character
spacing in which the space occupied by a single character on a line of text
depends on the individual design of the character. This is known as
proportional spacing. Scalable fonts are almost invariably proportionally
spaced.
Random Access Memory. The printer's memory in which fonts and macros
can be stored and where pages that are to be printed are composed.
A method of representing a graphic image as a series of zeroes and ones that
correspond to white and black dots respectively.
A method of plotting in the HP-GL and HP-GL/2 graphics language where
coordinates are specified relative to the point at which the last graphics
command terminated.
When you reset the printer you restore a base set of conditions. A reset can
either be performed using the control panel or by sending the printer a reset
command. There are two types of reset, the normal reset and factory reset. A
normal reset simply restores the current emulation mode with the most recent
control panel settings -- it does not change the emulation mode itself. A
factory reset makes LaserJet mode the current emulation mode and restores
the factory default environment.
See internal font.
Read Only Memory. Part of the printer's memory that contains the software
controlling the printer and the printer internal fonts. The ROM cannot be
altered.
A horizontal sub-division of the page whose height is equal to the VMI
(vertical motion index). The print position moves down the page a distance
equal to the row height when a line feed is performed.
A kind of typeface normally used for headlines. Sans serif typefaces do not
have little hooks (serifs) on the individual characters. This helps Sans serif
headline text stand out more prominently.
A font for which you can specify the character size. The printer will
automatically scale the characters to the size you require.
In HP-GL or HP-GL/2 mode you can use the SC command to scale graphic
images. The three types of scaling are known as anisotropic, isotropic and
point factor scaling.
Two imaginary points called P1 and P2 that define a rectangular area relative
to the picture frame. You can user the HP-GL or HP-GL/2 SC and IP or IR
commands to transform and scale images by changing the relationship
between the two scaling points.
A typeface for which you can choose a point size (height) in order to obtain a
particular font for printing. For example, you might select the Utah typeface
