Printers

1. Dot Matrix: The print head contains a grid of pins and different combinations of pins are pushed out to form different characters. The print head then hits a carbon ribbon leaving an imprint on the paper.

   • Advantages: Relatively cheap to buy, low operating costs, can print on continuous stationary
   • Disadvantages :Print quality is poor and important documents are not suitable to give to managers or customers, very slow - slowest out of all three printers

2. Ink-jet: They operate by heating the ink as it flows through a set of tiny nozzles. The heating process causes a small droplet of ink to form. This is then released as a single dot which forms part of a letter or image.
