The development of printers:

The printer was invented by John Vaught and dave Donald.

A device that prints computer operation results or intermediate results on paper in a specific format such as numbers, letters, symbols and graphics that people can recognize. Printers are developing in the direction of light, thin, short, small, low power consumption, high speed and intelligence.

With the rapid development of the Internet, it is predicted that the paperless era is coming, and the era of printers has arrived. However, the global consumption of paper is increasing exponentially every year, and the sales of printers are increasing at an average rate of nearly 8%.

All this indicates that printers will not disappear, but will develop faster and faster, and their application fields will become wider and wider.

From the appearance of the first printer in the world in 1885 to various needle printers, inkjet printers and laser printers, it took the lead in different years.
