Generally speaking, the higher the temperature, the darker the printed color, so the accuracy of the temperature control of the print head determines the quality of the print. According to research, the heat energy of the print head is quadratic with the voltage applied to the print head Quantitative relationship, the energy required by the print head depends on the image printed by the user. If the color of the image changes drastically, the energy required by the print head will also change sharply. This situation will cause the power supply voltage to be unstable. The voltage of the print head is also unstable, which will affect the print quality

The invention discloses a method for reducing the influence of the fluctuation of the power supply voltage on the thermal print head on the printing quality. A variation parameter between the power supply voltages on the thermal print head at a later moment; according to the variation parameter, an additional compensation power supply time is provided for the thermal print head at a later moment. Compared with the traditional technology, the present invention has reasonable design and simple steps. By detecting the variation of the power supply voltage on the thermal print head to adjust and control its power supply time parameters, it can make the printing energy change caused by the voltage change on the thermal print head Compensation is achieved to reduce the impact of power supply voltage fluctuations on the thermal print head on print quality.
Description
technical field [0001] The invention relates to the field of printer driving, in particular to a method for reducing the influence of power supply voltage fluctuations on thermal printing heads on printing quality. Background technique [0002] The working principle of the thermal printer is to rely on powering the semiconductor heating element (that is, the thermal print head) to make its temperature rise sharply. chemical reaction, so as to display a specific image on the paper; if it is in contact with a carbon ribbon or a ribbon, it will transfer their dyes to other media (such as paper, cards, etc.), so that it can also be printed on the paper A specific image is displayed on the media. Generally speaking, the higher the temperature, the darker the printed color, so the accuracy of the temperature control of the print head determines the quality of the print. According to research, the heat energy of the print head is quadratic with the voltage applied to the print hea...
