Dot matrix printer
Dot matrix printers have occupied an important place in the history of printers for a long time, from 9 pins to 24 pins, it can be said that the history of dot matrix printers runs through these decades. The reason why dot matrix printers can be popular for a long time is inseparable from its extremely low printing cost and good ease of use, as well as the special purpose of document printing. Of course, its low print quality and large working noise are also the root of its inability to adapt to the needs of high-quality, high-speed commercial printing, so its traces can only be seen in banks, supermarkets and other places where ticket printing is rare.
Color inkjet printers
Color inkjet printers have occupied the majority of the low-end market because of their good printing effect and low price advantages. In addition, inkjet printers also have more flexible paper processing capabilities, in the choice of printing media, inkjet printers also have certain advantages: can print envelopes, letter paper and other ordinary media, but also can print a variety of film, photo paper, disc covers, roll paper, T-shirt transfer paper and other special media, will be introduced as the focus below.
Laser printer
Laser printer is a new product of high-tech development, but also is expected to replace inkjet printers of a model, divided into black and white and color, it provides us with higher quality, faster, lower cost printing methods. Among them, the price of low-end black and white laser printers has dropped to several 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 an electrical signal and other pulses sent to the laser transmitter, under the control of this series of pulses, the laser is regularly released. At the same time, the reflected beam is sensed by the received drum. When the laser is emitted, a dot is generated, and when the laser is not emitted, it is blank, so that a line of dots is printed on the receiver. The receiver then turns a short fixed distance to continue repeating the operation. When the paper passes through the 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, fixed on the paper, and the whole process of printing is completed, which is accurate and efficient. Although the price of laser printers is much more expensive than inkjet printers, laser printers are much cheaper in terms of printing costs per 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 printer models for professional applications, such as thermal transfer printers and large-format printers. Thermal transfer printer is the use of transparent dye for printing, its advantage is professional high-quality image printing, can print close to the continuous tone of the photo to the picture, generally used for prepress and professional graphics output. Large format printers, its printing principle is basically the same as inkjet printers, but the printing width can generally reach more than 24 inches (61cm). Its main use has been concentrated in the field of engineering and construction. However, with the improvement of its ink durability and the increase of graphic resolution, large-format printers have begun to be used more and more in the fields of decorative publicity such as advertising production, large-scale photography, art photography and interior decoration, and have become an important member of the printer family.
