Introduction to the development history of laser printing
A printing technology developed in the 1960s, the first laser printer was born in 1971. Laser printing technology uses a laser beam to quickly "project" digital graphics or documents onto a photosensitive surface. Electron discharge occurs at the position hit by the laser beam, and then due to static electricity, it attracts some slender "toner" like a magnet. , The printing effect will come out. Because the core of its printing technology is laser imaging technology, this printing technology is called "laser printing technology".
The development of laser printers originated from the world's first electrostatic copier produced in 1948. From then on, scientists began to concentrate on studying the application of laser technology and laser modulation technology in printers. When it comes to the birth of laser printers, one cannot fail to talk about Gary Starkway, who is known as the "father of laser printers." In 1970, Gary Starkweizer was transferred to Palo Alto Research Center, and in November 1971, he developed the world's first laser computer printer. In 1977, Xerox's 9700 laser printer was put on the market, marking the beginning of an epoch-making printing industry.
The initial laser printers were bulky, noisy, took a long time to warm up, and the print quality was not satisfactory. There were fewer companies that could pay quite a lot of money, but the speed of technological innovation was very fast. The development of microcomputer control and laser printer production technology has become increasingly mature, and the cost has been continuously reduced. By the 1990s, production and sales have increased by leaps and bounds, and laser printers have also begun to become popular.
