Detailed Description
Referring to fig. 1 to 5, the two-color printing driving method of the present disclosure is applied to a thermal printer, and mainly performs two-color printing on additive thermal paper, where the color is a first color when the applied heat is low, and the color is a second color when the applied heat is high, and for example, red and black thermal paper is used.
When the two-color print driving method is executed, step S11 is first executed to receive print data including font information, pattern information, and color information, for which color information includes red information, black information, gradation information, and the like. In the editing stage, the color of the font or the pattern can be set, namely black, red and the shade degree thereof can be set.
Subsequently, step S12 is executed, image data is obtained by converting the print data, the image data is a dot diagram obtained by converting the print data, each line has 11 pixels as an example, the present application is described as follows, according to a density value of each pixel of a current print line of the image data and a driving pulse sequence (as shown in fig. 3) corresponding to the density value, that is, the density value is divided into 10 levels, which include, from light to deep, density 1, density 2 … to density 10, the corresponding density value is heated and driven by a 10-frame heating signal, and the driving pulse sequence corresponding to the density value is as follows:
concentration 1: 1000000000;
concentration 2: 1100000000;
concentration 3: 1110000000, respectively;
concentration 4: 1111000000, respectively;
concentration 5: 1111100000, respectively;
concentration 6: 1111110000, respectively;
concentration 7: 1111111000, respectively;
concentration 8: 1111111100, respectively;
concentration 9: 1111111110, respectively;
concentration 10: 1111111111.
and then obtaining multi-frame driving pulse data of each pixel point in the current printing line.
Then step S13 is executed, the same-frame driving pulse data of each pixel point in the current printing line forms a frame-by-frame heating signal, taking fig. 2 as an example of a target printing pattern, the pattern has 11 pixel points, starting from left to right, the first and second pixel points are black with the density of 10, the hexadecimal color code thereof is #231915, the tenth pixel point is light red with the density of 2, the hexadecimal color code thereof is # ef8575, the eleventh pixel point is light red with the density of 1, the hexadecimal color code thereof is # f3bbb2, the frame-by-frame heating signal is heated by a 10-frame heating on-off signal, so that when a row of heating elements are driven, the 10-frame-by-frame heating signals are respectively the 1-frame data1 "11111111111111111", the 2-frame data2 "11111111110", the 3-frame 3 "11111111111111111111111111100", the 4-frame data4 "11111111000", the 5-frame data5 "11111110000", the 6-frame data6 "11100000000", the 7378 "11100000000",23 ", the 10 th frame data10 "11000000000" takes the drive of the 5 th frame data5 "11111110000" as an example, and from left to right, the 1 st to 7 th heat generating elements generate heat by being driven by "1", and the 8 th to 11 th heat generating elements do not generate heat by being driven by "0".

The printer main control chip sends an EN enabling signal to enable the thermal printing head, then each CLK clock signal sends one bit of DAT image data until one frame of image data of the current line is sent, the LAT register latches the image data at a low level, and finally, a heating signal of the STB heating body is sent to the thermal printing head, and the low level is effective.
Finally, as shown in fig. 2, the leftmost two dots are heated 10 times, the density is 10 levels, and the dots are black, and the rightmost one dot is heated only once, the density is 1 level, and the dots are light red. Of course, in addition to the embodiment, other additive color type thermal paper may be adopted, and the driving method of the present embodiment may be adopted for both blue-black and yellow-black printing.
