Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The invention provides a method for improving the image uniformity of a thermal printer, and the specific steps are as follows:

[0027] S1. Data acquisition: acquire original data according to the image;

[0028] S2. Raw data grouping: Divide the heating points in a group of data to be printed into multiple data, and after all the data that is equally divided are the same, they are still the original data, and the number of times of equalization is var...

Abstract

The invention discloses a method for improving the image uniformity of thermal printers, and specifically relates to the field of thermal printers. The specific steps are as follows: S1. Data acquisition: acquire original data according to images; S2. Group original data: group the original data obtained in step S1 The data is equally divided three times, and three arrays A, B, and C are established, and the three data after the equalization are saved respectively. First, the three arrays are cleared to 0; S3, circularly querying the original data; S4, heating and printing. The invention divides the image to be printed into multiple transmissions and heats it by using the data equalization technology. The number of image points heated each time is the same, and then uses the method of heating all points at one time, so the printed image is very uniform and effective. The printing quality of the printer is improved, and the competitiveness of the product is improved. Since the power supply current of the battery is reduced, a battery with a large output current is not needed, thereby saving battery cost.

Description

technical field [0001] The invention relates to the technical field of thermal printers, and more specifically, the invention relates to a method for improving image uniformity of thermal printers. 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. Its principle is similar to that of a thermal fax machine. The image is created by applying heat, which creates a chemical reaction in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperatures accelerate this chemical reaction. When the temperature is lower than 60°C, it takes quite a long time, even several years, for the paper to become dark; and when the temperature is 200°C, this reaction will be completed within a few microseconds. [0003] In portable thermal printers, ...
