From simple dot matrix printer to more advance versions like laser and color ink jet printer. While the former prints in black and white the latter is as the name suggest. These are modern day computer peripherals attached to deliver finest computer graphics and images. The evolution started with electronic line printers and daisy wheel which were followed by the popular dot matrix systems.
Desktop publishing required machines that delivered much higher resolutions and faster output. This was accomplished by laser printers which followed the dot matrix. As low cost solutions the ink jet systems replaced the older dot matrix printers. But as compared to laser jet the output was of much lower quality. The LED printer is another advancement that has taken place in the printing world.
