Laser printer
Soft and hard circuit board
The laser printer was born out of the laser phototypesetting technology in the late 1980s and was popular in the mid-1990s. It is a print output device that combines laser scanning technology with electronic photography technology. Its basic working principle is that the binary data information transmitted from the computer is converted into video signal through the video controller, and then the video signal is converted into laser drive signal by the video interface/control system. Then the laser scanning system generates a laser beam containing character information, and finally the electronic photography system makes the laser beam image and transfer it to the paper. Compared with other printing devices, laser printers have the advantages of fast printing speed and high imaging quality; However, the use cost is relatively high.
