Problems solved by technology

When it is necessary to print a line of 384 black dots, it is necessary to print in M ​​sections, and each section has 384 / M dots. However, when there are only a few dots in a line, but they are scattered among the M sections, if the method of heating M times is still used, inefficient

Embodiment 1

[0043] This embodiment provides a thermal printer segmentation printing method, such as figure 1 shown, including the following steps:

[0044] Step S100, dividing the heating area of ​​the thermal printer into N sections of sub-areas in the horizontal direction, and the heating area includes M heating points, so each sub-area includes M / N heating points;

[0045] Step S200, respectively counting the number of points to be heated in each sub-region, and the number of points to be heated in each sub-region is less than or equal to M / N;

[0046] Step S300, grouping N sections of sub-areas according to the number of points to be heated in each sub-area, so that the number of sub-areas in each group is the largest and the total number of points to be heated in each group P≤M / N;

[0047] Step S400, perform thermal printing according to the above grouping.

[0048] Among them, such as figure 2 As shown, step S300 specifically includes:

[0049] Step S301, determining the sub-ar...

example 1

[0063] After the printer receives a row of data to be printed, it counts the number of points to be heated for each sub-region according to the row of data. It can be understood that the number of points to be heated for each sub-region does not exceed 64 points. Such as Figure 4 As shown, the six sub-regions are respectively marked as A1-A6, and the statistical results are: 64 points, 48 ​​points, 10 points, 15 points, 20 points, and 30 points.

[0064] but

[0065] Step S301, determining that the sub-area with the largest number of points to be heated is the first sub-area, that is, A1 is the first sub-area;

[0066] Step S302, judging whether the number 64 of points to be heated in the first sub-area A1 is less than 64, if the result is no, execute step S303;

[0067] Step S303, take each first sub-area as a group, that is, the first sub-area A1 as a group, return to step S301, determine the sub-area with the largest number of points to be heated as the first sub-area, ...

example 2

[0075] After the printer receives a row of data to be printed, it counts the number of points to be heated for each sub-region according to the row of data. It can be understood that the number of points to be heated for each sub-region does not exceed 64 points. Such as Figure 5 As shown, the six sub-regions are recorded as B1-B6 respectively, and the statistical results are: 64 points, 3 points, 64 points, 5 points, 64 points, and 29 points. but

[0076] Step S301, determining that the sub-area with the largest number of points to be heated is the first sub-area, that is, B1, B3, and B5 are all the first sub-areas;

[0077] Step S302, judging whether the number 64 of points to be heated in the first sub-regions B1, B3, B5 is less than 64, if the result is no, execute step S303;

[0078] Step S303, each of the first sub-regions as a group, that is, each of the first sub-regions B1, B3, B5 as a group, return to step S301, determine the sub-region with the largest number of...

Abstract

The invention discloses a segmented printing method and a segmented printing device of a thermal printer and the thermal printer and relates to the technical field of printing. The method comprises the following steps of averagely dividing a heating area of the thermal printer into N sub areas transversely, wherein the heating area comprises M heating points, and each sub area comprises M / N heating points; carrying out statistics on a to-be-heated point number of each sub area; grouping the N sub areas according to the to-be-heated point number of each sub area, wherein the sub areas of each group are the most and the total to-be-heated point number of each group is smaller than or equal to M / N; and carrying out heating printing according to groups. By dividing the heating area of the thermal printer into N sub areas, carrying out statistics on the to-be-heated point number of each sub area, grouping the N sub areas according to the to-be-heated point number of each sub area and finally, carrying out heating printing on the grouped groups, a problem that the printing efficiency is low as N segments are divided to print as a result of few to-be-heated points in the prior art is overcome. By way of segmenting, grouping and printing finally, the printing number of times is reduced and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a thermal printer segmentation printing method, device and thermal printer. Background technique [0002] At present, the principle of the thermal printer is that the thermal film used for color development cooperates with the stepping motor used for paper feeding to complete the heating and printing line by line. Specifically, take a thermal film with a width of 2 inches as an example. The structural principle of the thermal film is: Arrange 384 heating resistors on a straight line, and the control information of 384 heating resistors is sent to the thermal sheet through the SPI interface in binary stream. After heating, the heat-sensitive paper close to the heat-sensitive surface will change color due to heat, and realize the printout of one dot. The same is true for 384 dots in one line. When the dots are accumulated into a line, a line of content in a printed pattern can be ...
