RTS
Glossary G-13
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 network interfaces.
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
and 600x600 dpi 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.
RTS
An acronym for Request To Send. RTS is a signal sent from the host to the
printer indicating it is ready to send data.
