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
bitmap.
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.
Remote Console
A feature in QMS Crown printers allowing users to configure the printer and
monitor printer conditions over the Ethernet network interface.
Resident
Data or information Permanently stored in the printer’s memory or disk.
Resident Fonts
Fonts permanently stored in the printer's memory or disk; 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 300x300,
600x600, and 1200x1200 dpi resolutions. See also
asymmetric resolution
and symmetric resolution.
RISC
An acronym for Reduced Instruction Set Computing, a microprocessor
design that focuses on rapid and efficient processing of a relatively small
set of instructions.
ROM
An acronym for Read Only Memory. This type of memory contains data
and/or printer-executable instructions that can be read but not modified.
On QMS Crown printers, the operating system code, resident fonts, and
resident emulations are all stored in ROM. This information is not lost when
the printer’s power is turned off.
