Abstract
An inkless printing method with heating process is disclosed. In the method, a conventional printing paper (15) is used, and a printing head (4,27) contacts the printing paper directly or indirectly. A heating element (13,22) is placed in the printing head(4,27), which provides heat energy to cause a color change in a surface layer of the paper, thereby producing a character or an image. When the printing head (4,27) contacts the printing paper directly, a temperature of the printing head (4,27) is set to 100-1000° C.; and a stagnation time of the printing head (4,27) is set to 0.1-100 ms; when the printing head (4,27) contacts the printing paper indirectly, a temperature of the printing head (4,27) is set to 200-1000° C. The method does not need to use toner, ink or paint, and only needs conventional printing paper (15) and said heating process to achieve printing effect. A printing head unit to be used in said printing method is also disclosed.
