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 processor
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.
error diffusion
This halftoning setting smoothes out edges by blending dots of varying colors.
font
A style of type designated by a family name.

A scale of shades of gray from black to white. Grayscale is used to represent colors
when printing with black ink only.
halftones
Patterns of black or colored dots used to reproduce an image.
halftoning
Method of using dot patterns to represent an image. Halftoning makes it possible to
produce varying shades of gray using only black dots, or a nearly infinite array of
colors using only a few colors of dots. See also halftones.
high speed printing
Printing in which images are printed in both directions. This provides faster
printing.

you turn on the printer or reset the printer.
ink jet

spraying ink onto paper.
