Printers ImpactNon-Impact

Impact An impact printer forms characters and graphics on a piece of paper by striking a mechanism against an inked ribbon that physically contacts the paper

Impact Two Common Types: Dot-Matrix & Line Printer

Impact Dot-Matrix

Impact Line

Non-Impact InkJet & Laser/LED

InkJet is a type of non-impact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper

InkJet Printers are measured in Dots Per Inch or Dpi The more dots per inch the finer and clearer the print 300, 600, 1200, 2400, 4800, 5400 dpi are some common inkjet resolutions

InkJet All modern inkjet printers require no more than dpi images or text to be able to print at the maximum resolution available on the printer

Laser Utilizes a laser beam, a highly focused beam of light, to write letters and draw pictures on paper via rotating mirrors and the principle of static electricity utilizing dry toner

Laser

LED LED technology uses a Light Emitting Diode printhead as a light source within the imaging device. Unlike laser systems, the LED printhead is solid-state and has no moving parts.
