Printer control mode
This printer has three control modes: Canon Extended mode, BJ mode, and
Epson LQ mode. The printer control mode determines the features the
printer supports.
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.
Printing area
The area of a sheet of paper on which a printer can reproduce text or
graphics (the printing area is smaller than the paper). On this printer, the
printing area varies depending on the type of paper being used.
Proportionally spaced font (PS font)
A font in which each character is given an amount of space proportional to
its size—less for an i and more for a w.
Proportional spacing
The spacing of characters according to the width of each character. This
variable spacing between each character closes up awkward space and
makes text easier to read.
PS
Stands for proportionally spaced.
R
RAM
Random Access Memory. Printer memory that is used for temporary
storage of information you want to print and downloaded fonts.
Reset
A way to clear printer errors; turn the printer's power off and then back on
again.
Resident font
A font that is built into the printer, as opposed to one that must be
downloaded from your computer. Resident fonts are stored in ROM. The
fonts available depend on the printer control mode you are using: BJ mode
or Epson LQ mode. See also Internal 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 x 360 dpi.
