QMS 3825/3225/2025 User’s Guide G-12
Resolution
A measurement of the dots-per-inch (dpi) in output material, either printed
or displayed, as in a “high-resolution monitor.” Your printer offers a choice
of resolutions.
RISC
Reduced Instruction Set Computing. A microprocessor design that focuses
on rapid and efficient processing of a relatively small set of instructions.
ROM
Read Only Memory. ROM is a more stable kind of memory that RAM.
Information stored in ROM is retained and can be retrieved each time the
machine is activated.
RTS
Request To Send. RTS is a signal sent from the host to the printer indicating
it is ready to send data.
Screen Font
A font designed for display on a computer screen. Screen fonts usually
have corresponding printer fonts.
SCSI
An acronym for Small Computer System Interface. Pronounced “scuzzy,”
this term refers to an interface used for connecting peripherals.
Serial
A data transmission technique that sends each bit sequentially over a single
line. A serial interface is a connection between a computer and a printer
in which information is transmitted sequentially.
SIMM
Single In-Line Memory Module, a small circuit board designed to
accommodate surface-mount memory chips. SIMMs use less board space
and are more compact than more conventional memory-mounting
hardware.
SIO
Simultaneous Interface Operation, the capability of printing to all of the
printer’s concurrently active ports rather than being restricted to one.
