Embodiment 1

[0038] figure 1 A schematic flowchart of the first thermal printing method provided by the embodiment of the present application is shown, and the details are as follows:

[0039] In S101, the to-be-printed data of the current printing line and the printed data of the previous printing line are acquired.

[0040] In a thermal printer, there is a print data buffer unit. For example, a ring buffer of a thermal printer is a continuous readable memory applied by a Microcontroller Unit (MCU) of the thermal printer for storing print data. Before starting printing, the MCU writes the print data to be printed into the print data buffer unit, wherein each data bit of the print data corresponds to a print pixel on the finally printed printing paper.

[0041] During printing, the print data is specifically divided into multiple lines of print data, and by reading the print data line by line, heating printing of each line is completed in turn. Specifically, in each line of print data, e...

Abstract

The invention is suitable for the technical field of printing, and provides a thermal printing method and device and terminal equipment. The method comprises the steps that the to-be-printed data of acurrent printing line and the printed data of a previous printing line are obtained; to-be-heated points of a thermal printing head are determined according to the to-be-printed data; discontinuous heating points in the to-be-heated points are determined according to the to-be-printed data and the printed data; the to-be-heated points are heated according to the first heating duration to finish first heating printing of the current printing line; and the non-continuous heating points are heated according to the second heating duration to finish second heating printing of the current printingline. According to the embodiment of the thermal printing method and device and the terminal equipment, the problems of non-uniform printing and blooming caused by non-uniform temperature in thermal printing can be solved.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a thermal printing method, device and terminal equipment. Background technique [0002] Thermal printers are widely used due to their small size, low noise, easy paper loading, fast printing speed, and high-density printing. [0003] There are multiple heating elements installed on the thermal print head of the thermal printer, one of which corresponds to a point. According to the data in the data buffer area (data 1 indicates the point that needs to be heated, data 0 indicates the point that does not require heating), Determine the points that need to be heated in the thermal print head when printing the current line, and heat these points once, when the printing paper coated with chemical pigments encounters high temperature, it will react to display black or other colors. While heating and printing the current line, the paper is driven by the paper feeding roller...
