What is a laser printer

Laser printer is a print output 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 signal is The interface/control system converts the video signal into a laser driving signal, then the laser scanning system generates a laser beam carrying character information, and finally the electrophotographic system images the laser beam and transfers it to paper.

Laser printer is a print output device that combines laser scanning technology and electrophotography technology.

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.

A laser printer is a printer. It does not have a copy function. It is a machine that combines copying and printing. It is not called a printer, but a copier or a multifunctional machine. And a laser printer is not There are only black and color. From the functional structure, the laser printer is divided into two parts: the print engine and the print controller. In the laser printer, the function of the print controller is to communicate with the computer through the interface or network and receive the information sent by the computer. Control and print information while transmitting printer status to the computer.

When using a laser printer, you need to replace the toner cartridge, photosensitive drum, and heating component. The toner cartridge has the shortest life, the photosensitive drum comes second, and the heating component has the longest life. Generally, according to The machine is designed to print pages per month, replace the toner cartridge once a month, the photosensitive drum once a year, and the heating component every two and a half years.
