Thermal history control method for thermal printing head, thermal printer and computer-readable storage medium

Abstract

The invention provides a thermal history control method for a thermal printing head, a thermal printer and a computer-readable storage medium. The thermal history control method comprises the steps ofreceiving printing data, obtaining image data according to the printing data, obtaining on-off data of a current printing row, a previous printing row and a next printing row of a heating body of thethermal printing head from the image data, determining a driving mode of the heating body according to the on-off data and a truth-value table, and outputting the history data corresponding to the driving mode to the thermal printing head to drive the heating body to operate. By predicting and judging the accumulated heat of a heating element of the printing head in advance and setting and inquiring the truth-value table, the heating time of the heating body can be effectively controlled, so that the printing quality is improved by smooth heating and smooth heat dissipation, a printed font orimage is clearer, and trailing smear is avoided.

Description

technical field [0001] The invention relates to the field of thermal printing, in particular to a thermal history control method of a thermal print head, a thermal printer and a computer-readable storage medium. Background technique [0002] With the popularization and application of thermal printers in all walks of life, thermal printing structures are not only used in bank ATMs, cash register terminals, takeaway terminals, catering terminals and e-commerce delivery terminals, especially for catering and e-commerce , Printing in the express delivery industry is growing rapidly, which puts forward higher requirements for the stability and durability of printers. [0003] The core printing component in a thermal printer is the thermal print head, which is the main execution unit for printing images on thermal printers such as bills or barcodes. The thermal print head is composed of a row of heating elements. Relatively dense, ranging from 200dpi to 600dpi, these heating elem...

AI Technical Summary

Problems solved by technology

[0005] refer to figure 1 , due to the principle of the heating element being energized and heated, heat accumulation and dissipation will inevitably occur, and there is a certain delay in heating and heat dissipation. In high-speed printing, it is easy to cause insufficient color density or smearing of font patterns. Now, Seriously affect the print quality
