print server
The print server acts as a post office for all print jobs sent over a network. It receives
the jobs and then distributes them to the assigned printer. It also holds extra print
jobs while the printer is busy. See also print queue.
print queue
When your printer is busy printing a print job, any additional print jobs sent to the
printer are placed in a waiting line, or print queue, until they can be printed. The
print queue may be on a network print server, or on your local server, depending
on the computer to which the printer is connected.
RAM
Random Access Memory. The portion of the printer's memory used as a buffer and
for storing user-defined characters. All data stored in RAM is lost when the printer
is turned off.
reset
To return a printer to its defaults either by sending a command, an INIT signal, or
by turning the printer off and then back on.
resolution
The number of dots per inch used to represent an image.
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 setting prints shaded areas as they appear on screen, instead of printing them
as halftones.
self test
A method for checking the operation of the printer. When you run the self test, the
printer prints the characters stored in its ROM.
