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.
