1, the price is high.
Laser printers on the market are more expensive than others. Laser printers use toner cartridges for printing. A box of toner can print about 3,000 to 5,000 pages, but it is relatively expensive to buy a new toner cartridge or replace the toner in the toner cartridge. There are also requirements for printing paper laser printers, and professional printing paper should be used.
2. There is some pollution.
Because the laser printer uses toner to print, the toner may fall into the air during use, and it is easy to produce dust pollution when filling the toner. Relatively speaking, the radiation of laser printers is relatively large, which has a certain impact on the human body.
3, the price is more expensive than consumables.
Laser printers use toner cartridges, and a box of toner cartridges can print about 3000 to 5000 pages, but it is relatively expensive to buy a new toner cartridge or replace the toner in the toner cartridge.
4. It is not allowed to print multiple copies with copy paper at the same time, which requires high paper.
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.
