Abstract

The invention discloses a thermal printer and a control method of the thermal printer. Then thermal printer comprises a thermal printing head. In the control method, the thermal printing head is controlled to scan original manuscripts to obtain image data of the original manuscripts. The thermal printing head is not only used for carrying out printing work, but also scanning work can be carried out, and the problem that the thermal printer with a scanning function is complex in structure is solved.

Description

technical field [0001] The invention relates to the printing field, in particular to a thermal printer and a control method for the thermal printer. Background technique [0002] figure 1 It is a schematic diagram of the corresponding relationship between the heating element and the medium of the traditional thermal print head. As shown in the figure, the thermal print head includes a plurality of heating elements 20, and these heating elements 20 are equidistantly arranged in a row. The number of heating elements 20 is set according to the lateral resolution of the printing head. When the horizontal resolution of the print head is 203 dots / inch, the heating elements 20 are arranged at a density of 203 dots per inch. The heating element 20 is usually a thermistor. When the heating element 20 is energized, the thermistor generates heat to cause chemical changes in the heat-sensitive layer on the surface of the printing paper, thereby developing color. Since each heating e...
