Types of printer:

Laser jet- 8-200 ppm

Inkprint- 2-6 ppn

Dot matrix-6 dpi

Laser jet is the best type of printer as if you where to get it wet the ink would not run off and can print loads off at a time.

Inkprint is a standard home printer as it is all you need for home because unless you print of a lot of work it is an easy to use printer.

Dot matrix is one of the first printers which has a variety of dots which change shape for the different letters but it is very slow.
