Development history of laser printer;
Laser technology appeared in the 1960s, and its real application began in the early 1970s. The earliest laser transmitter is an electronic laser tube filled with He-Ne gas, which is very large and its practical application is greatly limited.
In the late 1970s, semiconductor technology became mature. Semiconductor lasers were born, and high-sensitivity photosensitive materials were discovered. Coupled with the development of laser control technology, laser technology has matured rapidly and entered the practical application field.
Researchers, represented by the United States and Japan, have developed semiconductor laser printers on the basis of electrostatic copiers, combining laser technology and computer technology. This kind of printer has good printing quality, high speed and no noise, and soon it is widely used.
