ColorSync
Macintosh software that is designed to help you get WYSIWIG (what you see is
what you get) color output. This software prints colors as you see them on your
screen.
control code
Special codes used to control printer functions, such as performing a carriage return
or line feed.
cpi (characters per inch)
A measure of the size of text characters, sometimes referred to as pitch.
default
A value or setting that takes effect when the equipment is turned on, reset, or
initialized.
default-setting mode
A feature that allows experienced users to make special settings that they may not
be able to make in their software or the driver.
dithering
A halftoning method in which dots are arranged in an orderly pattern. Dithering
works best for printing images with solid colors, such as charts and graphs. See also
Halftoning.
dot matrix
A method of printing in which each letter or symbol is formed by a pattern (matrix)
of individual dots.
dpi
Dots per inch. The dpi measures the resolution. See also resolution.
driver
A software program that sends instructions to a computer peripheral to tell it what
to do. For example, your printer driver accepts print data from your word
processing application and sends instructions to the printer on how to print this
data.
economy printing
Printing in which images are printed with fewer dots to save ink.
emulation
Emulation means using the control codes of another kind of printer. Most users will
never need to make this setting but some experienced users may find this helpful.
error diffusion
Error diffusion blends individual colored dots with the colors of the surrounding
dots to create the appearance of natural colors. By blending colored dots, the printer
can achieve excellent colors and subtle color gradation. This method is best suited
for printing documents that contain detailed graphics or photographic images.
