Printer driver
Software that sends printing instructions to a printer. The printer driver
keeps track of the attributes of a printer and the codes the program
must send to access those attributes.
RAM
Random Access Memory. Printer memory that is used for temporary
storage of information you want to print and downloaded fonts.
Resolution
The density of dots for any given output device. Expressed in terms of
dots per inch (dpi). Low resolution causes font characters and graphics
to have a jagged appearance. Higher resolution means smoother curves
and angles as well as a better match to traditional typeface designs.
Resolution values are represented by horizontal data and vertical data,
for example, 360 360 dpi. This printer can produce output with
resolutions up to 1440 720 dpi precision on special papers.
RGB
An acronym for Red, Green, and Blue; the three primary colors used in
the additive process to form a wide spectrum of colors.
