four-color printers also include a separate black ribbon

ranges from 160 to 300 dpi. Resolution is limited by

printers can produce prints from 3.5 by 5 inches up to
ink to produce images. Inkjet printers today are capable
of producing excellent continuous-tone color prints by
using variable-size dots of ink that are precisely
controlled. Inkjet printers are nonimpact printers that
use droplets of ink. As the head of the printer moves
across the surface of the paper, it shoots a stream of tiny
electrostatically charged ink drops at the paper.

being connected directly to imaging workstations
through an interface. This interface accepts digital
signals to produce color photographs.
to prints produced on color copiers is they are printed
on plain, bond paper stock Color copiers use a laser
device that fuses toner to paper to create the image.
