Printing method and device, printer and storage medium

Abstract

The invention discloses a printing method and device, a printer and a storage medium. The method comprises the steps: acquiring current line printing data, wherein the current line printing data comprise at least one printing point datum, and each printing point datum has a printing order M corresponding to the color depth; dividing the predetermined heating time of the current line into N sub-periods; generating a printing drive pulse sequence of each printing point datum according to the printing order M of each printing point datum, N and the random number assigned to each printing point datum, and randomly assigning the heating time of each printing point datum to the sub-period, corresponding to the printing drive pulse sequence, of the N sub-periods; driving a corresponding heating element of a printing head for heating according to the printing drive pulse sequence and reproducing the current line data on the printing medium. Simultaneous heating on all the printing point data is avoided and the heating pulse distribution consistency is reduced, so that the image points are relatively full.

Description

technical field [0001] The invention relates to the technical application field of printers, in particular to a printing method, device, printer and storage medium. Background technique [0002] The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed out. The principle is similar to that of a thermal fax machine: images are heated, Produced by a chemical reaction in the membrane. The chemical reaction of this thermal printer is carried out at a certain temperature, and high temperature will accelerate this chemical reaction. When the temperature is lower than 60°C, it takes a long time, even several years, for the printing paper to become dark. color, and when the temperature is 200°C, this reflection will be completed within a few microseconds.

AI Technical Summary

Problems solved by technology

[0004] 1. In the traditional heating method, the heating cycle of one row is only heated for a period of time at the front, and the image points produced by heating are not full enough, which will cause a slight gap between each row

[0005] 2. In the traditional heating method, when printing a line, all printing points will be heated at the same time in the front stage, and the peak current required is relatively large, that is, the instantaneous current required for printing is relatively large.
