Types of Printers

  • Non-impact
  1. Inkjet
    • Mainly print text and images by spraying ink droplets onto the paper
    • Advantages
      • Low cost, high-quality output, easy to use, pretty fast, quieter than dot-matrix
    • Disadvantages
      • Print head is less durable, expensive ink cartridges, not good for high volume
  1. Laser
    • Uses toner instead of ink.
    • 3 major components
    1. Drum cartridge
    2. Rotating mirror
    3. toner cartridge and roller
  1. All-in-one
  2. Plotter
  3. Thermal - A small portable printer
  4. 3D - A process of making a three-dimensional solid object virtually any shape from a digital model.
  • Impact (almost entirely replaced by Non-impact)
  1. Dot Matrix
    • A type of printer that produces characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the appropriate shape. Dot-matrix printers are relatively expensive and do not produce high-quality output. However, they can print to multi-page carbon copies, something laser and ink-jet printers cannot do.
    • Advantages
      • can print multi page carbon copies
      • can print 50 to 500 characters per second
      • print quality: Determined by the number of pins (the mechanisms that print the dots), it can vary from 9 to 24. The best dot-matrix printers (24 pins) can produce near letter-quality type, although you can still see a difference if you look closely.
    • Disadvantages
      • noisy
      • expensive
      • do not produce high-quality work
