Problems solved by technology

[0005] It can be seen that the current printing process of thermal printers is a serial process, and in the heating process, it is necessary to control the electronic heater to heat for a period of time, and it is also necessary to control the motor to move the paper for a period of time during the paper feeding process. The actual printing speed differs greatly from the fastest printing speed supported by the print head

Embodiment 1

[0036]Embodiment 1. In this embodiment, the hardware structure of the thermal printer does not need to be modified. The data processing is data loading, that is, during the printing process of the current dot row data, the next dot row data is loaded. see image 3 , the printing process of thermal printer includes:

[0037] On the thermal paper, the current dot line data to be printed in the thermal printer is printed. During the printing process, when the current dot matrix to be printed is When the data has unprinted next line of data, load the next line of data into the data register and latch it. After the time used for the printing process is reached, it is necessary to complete the printing of a line of data, which shows that it has been printed on the thermal sensor. Current point row data on paper.

[0038] It can be seen that in the embodiment of the present invention, when the printing processing is heating processing, it can be judged whether the current dot matr...

Embodiment 2

[0048] Embodiment 2. In this embodiment, the data processing is font conversion processing, that is, during the printing process of the current dot row data, the font conversion processing of the next dot matrix data is performed. Moreover, there are two or more buffer areas in the storage area of ​​the thermal printer, and each buffer area can store dot matrix data corresponding to all characters to be printed that the thermal printer can process at one time. In this way, when printing the current dot matrix data to be printed stored in the first buffer area, the time spent in the printing process can be used to convert the newly received characters to be printed, and store the converted dot matrix data in the first buffer. in the second cache. See the specific process Figure 4 , the printing process of thermal printer includes:

[0049] On the thermal paper, print the current dot line data that is currently to be printed in the thermal printer and that has been latched. D...

Embodiment 3

[0065] Embodiment 3. In this embodiment, data processing includes: data loading and font conversion processing, that is, in the process of printing the current dot row data, the loading of the next dot row data and the font conversion of the dot matrix data under the row are carried out deal with. Moreover, there are two or more buffer areas in the storage area of ​​the thermal printer, and each buffer area can store dot matrix data corresponding to all characters to be printed that the thermal printer can process at one time. Wherein, the current to-be-printed dot matrix data stored in the first buffer area. See the specific process Figure 5 , the printing process of thermal printer includes:

[0066] On the thermal paper, print the current dot row data that is currently to be printed in the thermal printer, and during the printing process, when the first buffer area of ​​the thermal printer is currently to be printed When the dot matrix data has unprinted next dot row da...

Abstract

The invention discloses printing method and device of a heat-sensitive printer, which are used for increasing the printing speed of the heat-sensitive printer. The printing method comprises the following steps of: carrying out printing processing on current dot-row data latched in current dot matrix data to be printed inside the heat-sensitive printer on heat-sensitive paper; carrying out data processing in the printing processing process of the current dot-row data, wherein the data processing includes the loading of next dot-row data and/or the matrix conversion processing of next dot matrix data to be printed; and after the using time of the printing processing is reached, displaying the current dot-row data already printed on the heat-sensitive paper.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a printing method and device for a thermal printer. Background technique [0002] Commonly used micro dot matrix printers are slow and noisy, which cannot meet the needs of some occasions. Micro thermal printers have the advantages of fast printing speed, low noise, high reliability, clear writing, small and light head, etc., and can meet the printing requirements of various occasions, so they are widely used. [0003] The working principle of the thermal printer is: a layer of transparent film is covered on the light-colored material, and the film becomes dark after heating for a period of time. The graphics are generated by chemical reactions in the film through heating. Here, the light-colored material is generally paper, and the transparent film is a heat-sensitive material. According to the characters to be printed, the thermal printer determines the corresponding...
