Laser printers are non-impact printers. Non-impact printers (such as laser, inkjet, thermal, etc.) have no mechanical parts that collide with the paper surface during operation, so strictly speaking they should not be called "hit" printers, but "hit" printers. Printing Press". Laser printers have high printing quality, high speed, and low noise when working, but the price is high.
Printer is a commonly used output device, which can be divided into two categories based on its working principle: impact type and non-impact type.
Impact printers (including dot matrix type, chain type, etc.) print characters by hitting the "machine head" on the paper. Its disadvantage is that it makes a lot of noise during operation, and its advantage is that the dot matrix type is relatively cheap.
Non-impact printers (such as laser, inkjet, thermal, etc.) have no mechanical parts that collide with the paper during operation, so strictly speaking they should not be called "hit" printing. machine, it should be called a "printing machine". However, people are still accustomed to calling it "laser printing", "inkjet printing" and so on.
Laser printers have high printing quality, high speed, and very little noise when working, but the price is on the high side. Although it also has a process of heating the paper when it works, it is only to fix the toner printed on the paper, and it does not display the characters through heating.
Laser printers were born out of laser phototypesetting technology in the late 1980s and became popular in the mid-1990s. It is a printout device that combines laser scanning technology and electrophotography technology. Its basic working principle is that the binary data information transmitted from the computer is converted into a video signal through the video controller, and then the video interface/control system converts the video signal into a laser drive signal, and then the laser scanning system generates a message containing character information. The laser beam is imaged and transferred to paper by an electrophotographic system. Compared with other printing equipment, laser printers have the advantages of fast printing speed and high image quality; however, the cost of use is relatively high.
