Abstract

The invention relates to the technical field of thermal printing control, in particular to a thermal printing control method which comprises the following steps: acquiring a point position index construction sequence, judging a jump extraction structure mutation position, dividing paragraphs, counting frequency to generate a thermal distribution diagram, correcting a boundary according to a density trend, and extracting representative points to generate a relation table. And comparing the thermal state to adjust heating parameters to complete printing control. According to the method, a structure jump boundary is constructed by extracting point position index differences, a heating distribution diagram group is generated by combining trigger frequencies and electric heating numbers, paragraph boundary positions are corrected according to a thermal density gradient trend, symmetrical representative points in frequency sorting are extracted to establish an activation index table, and thermal states of the representative points are compared with a thermal reference interval. The heating rhythm and the power-on duration are dynamically adjusted, local refinement of heat input control, rhythm self-matching of structure segments and dynamic balanced distribution of point position energy consumption are achieved, and clear expression of a printed image in a change area and the adaptive capacity of an overall heat control strategy are enhanced.
