ROM
Read Only Memory. A portion of memory that can only be read and cannot be
used for data storage. ROM retains its contents when you turn off the printer.
RGB
Red, green, and blue. These colors, in phosphors irradiated by the computer
monitor's electron gun, are used to create the additive array of screen colors.
sans serif
A type of font that does not have serifs, or lines crossing the ends of characters to
enhance readability. The entries in the index are printed in a sans serif font, but the
explanations are printed in a font with serifs.
scalable fonts
Fonts that can be enlarged or shrunk. Non-scalable fonts are called bitmap fonts
and they can't change in size.
screen pattern
This feature prints shaded areas as they appear on screen, instead of printing them
as halftones.
serial interface
See interface.
spool
The process by which the printer driver converts the print data into codes that your
printer understands. This data is then sent to the printer directly or to the print
server.
spool manager
A software program that converts print data into codes that your printer
understands. See also spool.
status monitor
A software program that allows you to check the printer's status, such as the
amount of ink remaining before printing.
subtractive colors
Colors produced by pigments that absorb some colors of light and reflect others.
See also CMYK.
unidirectional printing
Printing in which the print head prints in one direction only. Unidirectional
printing is useful for printing graphics because it allows more precise vertical
alignment than bidirectional printing.
user-defined characters
Characters that are defined and stored in the printer by the user. Also called
downloaded characters.
WYSIWIG
What-you-see-is-what-you-get. This term is used to describe printout that looks
exactly like it appears on screen.
