The printer was invented by John Walt and Dave Donald. A device that prints the results of computer calculations or intermediate results on paper in a prescribed format with numbers, letters, symbols, graphics, etc. that can be recognized by a person. 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, some people predict that the paperless era is coming, and the end of printers has arrived. However, global paper consumption is growing exponentially every year, and printer sales are increasing at an average rate of nearly 8%. All this indicates that printers will not disappear, but will develop faster and faster, and the field of application will become wider and wider.
