There are three major types of printers: dot matrix printer, inkjet printer, and laser printer. Inkjet printers were developed after dot matrix printers and have several prominent advantages such as small size, simple and convenient operation, low printing noise, and the ability to produce photo-like images when using special paper. After several years of development, the technology of inkjet printers has become quite outstanding; Laser printers have more advantages than inkjet printers because of their faster speed. The printing principle of laser printers is photocopying, so even if the paper is similar to newspaper, the result is much better. The printing density of laser printers is very high, and the smaller the powder particles of consumables, the higher the resolution of the printed image, which can be very close to the effect of a photograph.
Today, with inkjet and laser printers dominating the market, many people said a few years ago: "In the future, there will only be two types of printers: laser and inkjet, and dot matrix printers will soon be phased out." However, even though dot matrix printers have passed their peak period, compared to inkjet and laser printers, they are still favored by most users due to their simple structure, moderate price, mature technology, medium resolution and printing speed, diverse forms, and wide applicability. Especially in printing Chinese characters, dot matrix printers have incomparable advantages over other types of printers, especially for domestic users. Therefore, under the fierce competition of various types of printers, dot matrix printers still occupy a considerable proportion in China's printer market.
