Abstract

The invention discloses a non-carbon printer. The printer is provided with a laser transmitter. As the printer is provided with the laser transmitter, after a signal output by a computer is subjected to high-frequency modulation by a high-frequency modulation unit of the laser transmitter, a signal output by the high-frequency modulation unit is converted into a character dot matrix signal by a data conversion unit and then a laser beam with character information is directly irradiated onto a paper surface in a mode of centralizing energy by an optical unit, so that the paper surface scanned by the laser beam is instantaneously carbonized into brown writing and no carbon powder printing is realized. Therefore, the non-carbon printer is low-carbon and environmental-friendly.

Description

technical field [0001] The present invention relates to a printer, and more particularly to a printer that does not use carbon. Background technique [0002] As one of the most important output devices of various computers, the printer has been greatly developed with the development of computer technology and the increasingly perfect user needs. In recent years, various new and practical printers have emerged as the times require, changing the previous dot matrix printers dominating the world. At present, in the field of printers, three mainstream products have been formed: dot matrix printers, inkjet printers, and laser printers, each of which exerts its advantages to meet the different needs of users from all walks of life. [0003] Although the development of printers has brought great convenience to people's lives, the environmental problems and harm to the human body caused by it cannot be ignored. Generally speaking, the toner used in laser printer ink drums contains ...
