Problems solved by technology

The printing parameters are single, and the single-chip microcomputer parameters cannot be adjusted dynamically. Using fixed parameters, the best printing effect cannot be produced. For example, Chinese characters are printed better, but when printing dense QR codes, the heating time will be too long, resulting in blurred QR codes. and many more

Embodiment 1

[0023] The present embodiment for illustrating defects in the prior art and solution ideas of the present invention.

[0024] The existing single-chip thermal printer mainly processes images with low printing difficulty, and for the purpose of developing / improving printing capabilities, the existing solution is to process the image to be printed at a certain processing end (computer, complex processing chip and mobile phone and other devices with high processing power), and then transmit the printed content to the printer, the printer heats up according to the printing position of the printed content, and the paper is taken, this process exists if the printing document is very long, the content is a lot, Then the time required to draw a monochrome BMP diagram at the processing end will be very long; Printing parameters are single, single-chip microcomputer parameters can not be dynamically adjusted, the use of fixed parameters, can not print the best effect, such as Chinese word...

Embodiment 2

[0028] The present embodiment is used to explain the preferred protocol.

[0029] Some such as bills and the like of the image, including fonts and two-dimensional code, both of which use thermal printers, due to the functional limitations of the single-chip microcomputer and the limitations of the existing processing methods (can not set the appropriate printing parameters), the problem of poor printing effect, the present embodiment sets a variety of print types, and then these print types are attached to the parsing data, the printer can be realized when obtaining the data to be printed, while obtaining the corresponding printing parameters, such as:

[0030] Type 1, Chinese 24size; Type 2, ascii character 16size; Type 3, Chinese 24size bold double height; Type 4, QR code; Type 5, QR code; Type 6, Persian....

[0031] When you start to print this picture, you can tell the microcontroller through the transmission protocol, what is the main type of the current picture, and after ...

Embodiment 3

[0034] The present embodiment provides a mobile phone, suitable for a microcontroller-controlled thermal printer, the mobile phone comprising: receiving module 1 for obtaining an image to be printed, decomposing the image into several lines according to the preset branch rules; Processing module 2, for setting up parallel printing process and drawing process based on the processing power of the mobile phone, wherein the printing process is used to obtain printing permissions for thermal printers, the drawing process is used to draw monochrome bmp diagram line by line; Printing module 3, for whenever the drawing process completes the drawing of a line of monochrome bmp plot, start the printing process to parse the dot row corresponding to a line of monochrome bmp plot and send the parsing data to the thermal printer.

Abstract

The invention discloses a mobile phone control image printing method and the mobile phone. The method includes: including: S1, acquiring an image to be printed, and decomposing the image into several lines according to a preset branching rule; S2, setting a parallel printing process and a drawing process based on the processing capability of the mobile phone, wherein the printing process is used to obtain The printing authority of the thermal printer, the drawing process is used to draw the monochrome bmp figure line by line; S3, whenever the drawing process completes the drawing of a line of monochrome bmp figure, the printing process parses the corresponding line of monochrome bmp figure dot row and send the parsed data to a thermal printer. The mobile phone is used to perform the method. The invention divides the image to be printed into several lines, and can reduce the processing ability requirement of the single-chip microcomputer through the parallel printing process and the drawing process, and improve the processing efficiency and printing effect of the thermal printer.

Description

Technical field [0001] The present invention relates to the field of printing technology, in particular a mobile phone control image printing method and a mobile phone. Background [0002] The working principle of the thermal printer is that the print head is installed with a semiconductor heating element, the print head can be heated and contacted with the thermal printing paper after the needed pattern, the principle is similar to the thermal fax machine, the image is generated by heating, the chemical reaction in the film is generated, this thermal printer chemical reaction is carried out at a certain temperature, and the high temperature will accelerate this chemical reaction. The microcontroller of the low-cost thermal printer does not have a large storage space, nor does it have strong computing power, so it is impossible to put the word inventory in the flash of the microcontroller, nor can it make the microcontroller do the image splicing with the more difficult algorithm...
