Description

Technical Field

[0001] The present invention relates to the technical field of printers, and more particularly to an inkless laser black-and-white printer. Background Art

[0002] An inkless black and white laser printer is a printing device that does not require traditional consumables such as ink or toner. The working principle of an inkless black and white laser printer is similar to that of a traditional black and white laser printer, but the consumables and printing methods are different.

[0003] Specifically, inkless laser black and white printers use a special kind of paper, which will undergo a chemical reaction when exposed to laser light to form text or images. During the printing process, the printer irradiates the paper with a laser beam to carbonize or discolor certain areas on the surface of the paper, thereby achieving the printing effect. Compared with traditional laser black and white printers, the advantage of inkless laser black and white printers is that they do not require consumables such as ink cartridges or toner, so they can reduce printing costs and are more environmentally friendly.

[0004] In the existing inkless black and white laser printer, during the printing process, the paper is irradiated with a laser beam, causing physical and chemical changes on the paper surface to achieve the printing effect.
