RAM
An acronym for Random Access Memory, the memory your printer uses to
perform tasks. It can be written to and read from. Once a task is complete,
the memory is free again to be used for another file. This memory is volatile,
so if your printer loses power while a file is being sent, you must resend the
file. The number and type of features you can run simultaneously on your
printer depend on the amount of RAM available and how that RAM is
distributed. RAM can be increased by adding SIMMs. See also

RAM Disk
Also called a virtual disk. The RAM disk is an area of RAM that is used to
simulate an additional hard disk. Data can be written to and read from a
RAM disk more quickly than a hard disk, but a RAM disk loses any
information stored on it when the printer’s power is turned off. The frame
buffer and spooling buffer are RAM disk clients. See also

Raster Graphics
The system of forming graphics using a bitmap, or grid of small dots, is
called raster graphics. The term “raster” denotes the Cartesian grid system
in which the dots are arranged. Bitmaps can define images, shapes, or
characters created with a specific number of dots per inch. See also

.
Rasterization
The conversion of vector graphics (images described mathematically as
points connected by straight lines) to equivalent images composed of pixel
patterns that can be stored and manipulated as sets of bits.
Resident
Permanently stored in the printer’s memory.
Resident Fonts
Fonts permanently stored in the printer's memory; also called internal fonts.
Resolution
A measurement of the dots per inch (dpi) in output material, either printed
or visual, as in a high-resolution monitor. Your printer features a 300x300,
600x600, and 1200x600 dpi resolution.
