Dot-Matrix Printer:

It is a character printer that print one character at a time. This Printer can form characters and all kinds of images as pattern of dots. Since dot matrix printer produce printed output as pattern of dots, they can print any shape of character that a program can describe. They therefore, can print many special characters, different sizes of print, and also have the ability to print graphics such as charts and graphs.

Dot Matrix Printer

Dot Matrix printer are normally haves slow printing speeds ranging from 30-600 characters per second. They are available at very low cost. These types of printers are generally used to print the shipping invoices.

Inkjet Printers:

After passing through a reflecting plate, it forms the desired letter/shape at the desired place. It is also a Character printer but it produces high quality output than dot matrixprinters because these printers form characters with very tiny ink dots.

Inkjet printers are slower than dot matrix printer as inkjet printing speed is 40- 300 characters per second. Inkjetprinter is also more expensive than dot matrix because it produces the high quality prints with more transformed technology. These printers are very popular because they are less expensive than laser printers and can print faster and accurate than dot matrix and other impact printers.

Drum Printer:

Drum printer is a line printers that print one line at a time. In addition the drum printer is also the impact printer. In this Printer it has a set of  hammers mounted in front of the drum in a manner that an inked ribbon and paper can be placed between the hammers and the drum. Than the drum rotates at a high speed.
