Difference between laser and dot matrix printer : Like laser and dot-matrix printers, ink-jet printers conjointly form images with very little dots. ink-jet printers spray tiny, electrically charged droplets of ink from four nozzles through holes in a matrix at high speed onto paper. Most color printing is completed on ink-jets as a result of the nozzles can hold four different colors. Moreover, ink-jet printers can match the speed of dot-matrix printers (120-240 characters per second, or 1-4 pages per minute). they’re even quieter than laser printers and produce an equally high-quality image.
A variation on ink-jet technology is that the bubble-jet printer, which uses miniature heating parts to force specially developed inks through print heads with 128 small nozzles. The multiple nozzles print fine pictures at high speeds. This technology is often used in portable printers.
