Answer:
The first computer printer designed was the mechanically driven apparatus by Charles Babbage for his difference engine in 19th century; however, his mechanical printer design was not the built until 2000.
The first patented printing mechanism for applying the marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for the electrostatically depositing ink on the controlled areas of the receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. ink was a red stamp-pad ink manufactured by Phillips Process Company of Rochester, NY under name Clear Print. This patent (US3060429) led to Teletype Inktronic Printer product delivered to customers in the late 1966.
The first compact, lightweight digital printer was EP-101, invented by the Japanese company Epson and released in 1968, according to Epson.
The first commercial printers generally used mechanisms from electric typewriters and the Teletype machines. The demand for the higher speed led to development of new systems specifically for the computer use. In the 1980s there were daisy wheel systems similar to the typewriters, line printers that produced similar output but at much higher speed, and dot-matrix systems that could mix text and graphics but the produced relatively low-quality output. The plotter was used for the those requiring high-quality line art like blueprints.
