Abstract

A thermal printer and a control method for the thermal printer. The thermal printer comprises a central control unit (1), a print head controller (3) connected to the central control unit (1), and a thermal print head (2) connected to the print head controller (3) and for use, under the control of the print head controller (3), in scanning a master copy to acquire image data of the master copy. This solves the problem of structural complexity in thermal printers having a scan feature.

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 a chemical change in the heat-sensitive layer on the surface of the printing paper, thereby developing color. Since each heating ...
