Dot matrix printer
Dot matrix printers have played an important role in the history of printers for a long time. From 9-pin to 24-pin, it can be said that the history of dot-dot printers runs through these decades. The reason why the stylus printer can be popular for a long time is inseparable from its extremely low printing cost, good ease of use, and the special purpose of receipt printing. Of course, its very low print quality and large working noise are also the root cause of its inability to adapt to high-quality, high-speed commercial printing needs, so it can only be used in banks, supermarkets, and other places where ticket printing is rarely used.

Color inkjet printer
printer
Color inkjet printers have occupied the vast low-end market because of their good printing effect and low price. In addition, inkjet printers also have more flexible paper processing capabilities. In the choice of printing media, inkjet printers also have certain advantages: they can print ordinary media such as envelopes and letter paper, as well as various film, photo paper, Special media such as CD covers, roll paper, T-shirt transfer paper, etc., will be introduced as a key point in the following.
laser printer
Laser printer is a new product of high-tech development, and it is also a model that is expected to replace inkjet printers. It is divided into black and white and color. It provides us with higher quality, faster and lower cost printing. Way. Among them, the price of low-end black and white laser printers has dropped to a few hundred yuan, reaching a level acceptable to ordinary users. Its printing principle is to use a raster image processor to generate a bitmap of the page to be printed, and then convert it into a series of pulses such as electrical signals and send it to the laser transmitter. Under the control of this series of pulses, the laser is regularly release. At the same time, the reflected light beam is received by the photosensitive drum. A dot is generated when the laser is emitted, and it is blank when the laser is not emitted, so that a line of dots is printed on the receiver. Then the receiver rotates a small fixed distance to continue the above operation. When the paper passes through the photosensitive drum, the colorant on the drum is transferred to the paper and printed as a bitmap of the page. Finally, when the paper passes through a pair of heating rollers, the colorant is heated and melted and fixed on the paper to complete the entire printing process, which is accurate and efficient. Although laser printers are much more expensive than inkjet printers, laser printers are much cheaper in terms of the cost of printing a single page. The price of color laser printers is generally around 2,000 yuan.
Other printers
In addition to the above three most common printers, there are several professional printer models such as thermal transfer printers and large format printers. Thermal transfer printers use transparent dyes for printing. Its advantage lies in professional high-quality image printing. It can print continuous-tone pictures that are close to photos. It is generally used for pre-press and professional graphics output. Large format printers have basically the same printing principles as inkjet printers, but the print width can generally reach 24 inches (61cm) or more. Its main use has been concentrated in the engineering and construction fields. But with the improvement of ink durability and the increase of graphics resolution, large-format printers have also begun to be used more and more in advertising production, large-scale photography, art photography and interior decoration and other decorative promotion fields, and they have become printers. An important member of the family.
