Description

Technical Field

[0001] The present application relates to thermal printing technology, and in particular to a thermal printing method, microprocessor chip, system and equipment. Background Art

[0002] At present, the working principle of thermal printers 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 thermal fax machines. The image is generated by heating and chemical reactions in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is below 60°C, it takes a long time, even several years, for the paper to turn dark; when the temperature is 200°C, this reaction will be completed in a few microseconds.

[0003] In the prior art, generally, a thermal printer has only one row of resistors. After the resistors heat up, they leave color on the printing paper. The higher the temperature, the darker the print, and the lower the temperature, the lighter the print. The resistors have only two conditions: heated and unheated. When printing an image, the second line is printed after the first line is printed, and so on.

[0064] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0065] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0066] At present, the working principle of thermal printers 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 thermal fax machines. The image is generated by heating and chemical reactions in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is below 60°C, it takes a long time, even several years, for the paper to turn dark; when the temperature is 200°C, this reaction will be completed in a few microseconds.

[0067] In one example, generally, a thermal printer has only one row of resistors. After the resistors heat up, they leave color on the printing paper. The higher the temperature, the darker the print, and the lower the temperature, the lighter the print. The resistors only have two conditions: heated and unheated. When printing an image, the second row is printed after the first row is printed, and so on. However, in the prior art, when the same resistor is heated for multiple consecutive rows and the next row is not heated, the next row may be printed tailing due to excessive temperature, or, when the same resistor is not heated for multiple consecutive rows and then one row is suddenly heated, the next row may be printed too lightly due to too low temperature. Therefore, the temperature of the resistor is unstable, resulting in poor printing quality.

[0068] The present application provides a thermal printing method, microprocessor chip, system and equipment, which are intended to solve the above technical problems in the prior art.

[0069] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0070] Figure 1 A schematic diagram of a thermal printing method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0071] Step 101: Get a print request.

[0072] Exemplarily, the execution subject of this embodiment can be a thermal printing device, or a terminal device, or a thermal printing device or equipment, or other devices or equipment that can execute this embodiment, and there is no limitation on this. In this embodiment, the execution subject is introduced as a thermal printing device. First, a print request needs to be obtained. The print request is used to print the original image data.

[0073] Step 102: Determine printing information according to the printing request; wherein the printing information includes heating information of the current line to be printed, the line above the current line, and the line below the current line.

[0074] Exemplarily, the printing information includes heating information of the current line to be printed, the previous line of the current line, and the next line of the current line. The current line, the previous line, and the next line all refer to each line of thermal dots on the thermal paper. When printing each line of the original image data, according to the print request, three lines of printing information, i.e., the heating information of the current line, the previous line, and the next line are recorded, "0" is used to indicate that the corresponding point is not heated, and "1" is used to indicate that the corresponding point is heated, as shown in Table 1 below:

[0075] Table 1

[0076]

[0077] Step 103: Determine the total heating time required for the current row according to the printing information, where the total heating time includes the actual heating time of at least three pulses.

[0078] Exemplarily, printing a line requires at least three pulses, and the preset pulse time widths of the three pulses are equal or unequal, which is not limited to this, and the pulse time width is the heating time. The total heating time includes the actual heating time of at least three pulses, that is, the total heating time can be determined according to whether each pulse is heated within the respective actual heating time.

[0079] In this step, the pulse heating information of the current row can be directly calculated according to the heating information of the current row, the previous row and the next row in the print information. Alternatively, among the preset multiple heating levels, the target heating level of the current row can be determined according to the heating information of the current row, the previous row and the next row in the print information, and the actual heating duration of each pulse of the current row can be determined based on the mapping relationship between the preset heating level and the actual heating duration of each pulse.

[0080] Step 104: Print the current line according to the total heating time.

[0081] For example, during the total heating time, the current of the print head is turned on and the current line is printed. Similarly, after the current line is printed, the next line is the new current line, and step 102 is repeated, which will not be described in detail here.

[0082] In an embodiment of the present application, a print request is obtained. Based on the print request, print information is determined; wherein the print information includes heating information of the current line to be printed, the line above the current line, and the line below the current line. Based on the print information, the total heating time required for the current line is determined, and the total heating time includes the actual heating time of at least three pulses. Based on the total heating time, the current line is printed. In this solution, when printing the current line, attention is paid to the printing of the same resistor in the previous line and the next line, and the pulse heating information of the current line is determined by any combination of the pulse time of the current line according to the printing of the current line, the previous line, and the next line, so that the printing temperature can be maintained within a suitable range within the printing cycle, avoiding the problem of print tailing due to excessively high temperature and printing too shallow due to excessively low temperature, and solving the technical problem of poor print quality caused by unstable temperature of thermal printers.

[0083] Figure 2 A schematic diagram of another thermal printing method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method includes:

[0084] Step 201: Get a print request.

[0085] For example, this step can be referred to Figure 1 Step 101 in the above is not described in detail.

[0086] Step 202: Determine printing information according to the printing request; wherein the printing information includes heating information of the current line to be printed, the line above the current line, and the line below the current line.

[0087] For example, this step can be referred to Figure 1 Step 102 in the above is not described in detail.

[0088] Step 203: Determine the total heating time required for the current row according to the printing information; the total heating time includes the actual heating time of at least three pulses.

[0089] In one example, the actual heating duration indicates whether each pulse is heated within the respective actual pulse time width.

[0090] Step 203 includes two implementations:

[0091] The first implementation method of step 203: the heating information indicates whether heating is performed; based on the heating information of the current line in the printing information, the actual heating duration of the first pulse of the current line is determined; based on the heating information of the current line in the printing information and the heating information of the previous line, the actual heating duration of the second pulse of the current line is determined; based on the heating information of the current line, the heating information of the previous line and the heating information of the next line in the printing information, the actual heating duration of the third pulse of the current line is determined.

[0092] The second implementation method of step 203: determine the target heating level of the current row according to the printing information; determine the actual heating duration of each pulse of the current row based on the mapping relationship between the preset heating level and the actual heating duration of each pulse; wherein the heating level includes a preset number of grades, and the heating level is confirmed based on the preset correspondence with the printing information and the printing information.

[0093] Exemplarily, printing a line requires at least three pulses, and the preset pulse time widths of the three pulses are equal or unequal, which is not limited to this, and the pulse time width is the heating time. The pulse heating information represents the total heating time required to print the current line, and the total heating time includes the actual heating time of at least three pulses, that is, the total heating time can be determined based on whether each pulse is heated within its respective actual heating time.

[0094] In the first implementation, the heating information, that is, the truth value "0" or "1", represents whether heating is performed. Table 2 is a truth table. As can be seen from Table 2 below, the actual heating duration of the first pulse of the current row is determined based on the heating information of the current row in the print information. For example, in the truth value of the first row in Table 2, the heating information of the current row E is "0". Since PulseA=E=0, it can be determined that the truth value of the actual heating duration PulseA of the first pulse of the current row is "0". Alternatively, in the truth value of the third row in Table 2, the heating information of the current row E is "1". Since PulseA=E=1, it can be determined that the truth value of the actual heating duration PulseA of the first pulse PA of the current row is "1".

[0095] According to the heating information of the current line and the heating information of the previous line in the printing information, the true value of the actual heating duration PulseB of the second pulse PB of the current line is determined. For example, in the true value of the first line in Table 2, the heating information of the current line E is "0", and the heating information of the previous printed line D is "0", because It can be determined that the actual heating duration PulseB of the second pulse of the current line is "0". Alternatively, in the third line truth value in Table 2, the heating information of the current line E is "1", and the heating information of the previous printed line D is "0", because It can be determined that the true value of the actual heating duration PulseB of the second pulse of the current row is "1".

[0096] According to the heating information of the current line, the heating information of the previous line and the heating information of the next line in the printing information, the true value of the actual heating duration PulseC of the third pulse PC of the current line is determined. For example, in the true value of the first line in Table 2, the heating information of the current line E is "0", the heating information of the previous printing line D is "0", and the heating information of the next printing line F is "0", that is, because It can be determined that the true value of the actual heating duration PulseC of the third pulse of the current line is "0". Alternatively, according to the true value of the second row in Table 2, the heating information of the current line E is "0", the heating information of the previous printed line D is "0", and the heating information of the next printed line F is "1", that is, because It can be determined that the true value of the actual heating duration PulseC of the third pulse of the current line is "1", so when the printing information of the current line E and the previous line D are not printed and the next printing line F is printed, it is determined that the third pulse PC needs to be heated.

[0097] Table 2

[0098]

[0099] Therefore, the logic of determining each pulse is simple, and the actual heating time of each pulse can be obtained by directly calculating the heating information, and then printing can be performed according to the actual heating time of each pulse, which is convenient and quick.

[0100] In the second implementation, based on the printing information, it can be determined whether the current row, the previous row, and the next row are heated, and then the target heating level of the current row is determined. The target heating level corresponds to a preset total heating time, and the total heating time can be divided into N levels (2≤N≤8). Based on the mapping relationship between the preset heating level and the actual heating time of each pulse, the actual heating time of each pulse in the current row is determined. Therefore, different combinations of at least three pulses can be used to control the heating temperature during printing using the total heating time. As shown in Table 3 below, if N=5, the corresponding situation between the printing information of three rows and the three pulses is as follows:

[0101] Table 3

[0102]

[0103] If the accuracy of the printing temperature is high, N=6, and the correspondence between the three lines of printing information and the three pulses is shown in Table 4:

[0104] Table 4

[0105]

[0106] Among them, "1" represents the corresponding pulse control heating, and "0" represents the corresponding pulse control no heating. Therefore, the printing accuracy can be flexibly adjusted according to actual needs; in addition, the corresponding relationship between the printing level and the printing information can be adjusted according to different printing environments to improve the printing effect in different environments.

[0107] Step 204: According to the total heating time, the actual heating time of each pulse is obtained in sequence.

[0108] In one example, the order of acquiring each pulse is a preset order or a random order.

[0109] For example, according to the total heating time, the actual heating time of each pulse can be obtained in sequence according to a preset order. Alternatively, the actual heating time of each pulse can be obtained in sequence according to a random order, and the order is not limited. That is, the heating order of the pulses is not distinguished, and it is only necessary to ensure that the total heating time is correct.

[0110] For example, Figure 3 A temperature curve diagram of a thermal printing method provided in an embodiment of the present application, such as Figure 3 As shown, taking the high level representing heating as an example, a pulse situation and a heating situation are included when the high level durations of the first pulse PA, the second pulse PB, and the third pulse PC are the same, and the sending order of PA, PB, and PC is not distinguished.

[0111] Step 205: Print the current line according to the actual heating time of each pulse.

[0112] In one example, the preset pulse time widths of the pulses are equal or unequal.

[0113] Exemplarily, the preset pulse time widths of the pulses may be equal or unequal, and this is not limited. The thermal printing device may turn on the current of the print head and print the current line during the total heating time. Similarly, after the current line is printed, the next line becomes the new current line, and step 202 is repeated, which is not described in detail here. Therefore, the present application can complete thermal history printing with a minimum number of pulses, thereby improving the printing speed.

[0114] In an embodiment of the present application, a print request is obtained. Based on the print request, print information is determined; wherein the print information includes heating information of the current line to be printed, the line above the current line, and the line below the current line. Based on the print information, the total heating time required for the current line is determined; the total heating time includes the actual heating time of at least three pulses. Based on the total heating time, the actual heating time of each pulse is obtained in turn. Based on the actual heating time of each pulse, the current line is printed. In this solution, when printing the current line, attention is paid to the printing of the same resistor in the previous line and the next line, and the pulse heating information of the current line is determined by any combination of the pulse time of the current line according to the printing of the current line, the previous line, and the next line, so that the printing temperature can be maintained within a suitable range within the printing cycle, avoiding the problem of print tailing due to excessively high temperature and printing too shallow due to excessively low temperature, and solving the technical problem of poor print quality caused by unstable temperature of thermal printers.

[0115] Exemplarily, the duration of the pulse high level or low level represents the heating time, and here the high level represents heating as an example. Based on the above Table 3, Figure 4 A temperature curve diagram of another thermal printing method provided in an embodiment of the present application, such as Figure 4 As shown, N=5, the pulse conditions and heating conditions when the temperature level is 5, specifically including the temperature curves of the first pulse PA, the second pulse PB, and the third pulse PC within the preset temperature range. Figure 4 It can be seen that when the temperature level is 5, the temperature of the previous line of printing has been completely cooled. It should be noted that the temperature range can be between 85°C and 100°C, and there is no limitation on this.

[0116] For example, based on Table 3 above, Figure 5 A temperature curve diagram of another thermal printing method provided in an embodiment of the present application, such as Figure 5 As shown, N=5, the pulse situation and heating situation when the temperature level is 3, specifically including the temperature curve diagram of the first pulse PA, the second pulse PB, and the third pulse PC within the preset temperature range. Figure 5 It can be seen that when the temperature level is 3, the temperature of the previous line of printing is not completely cooled. It should be noted that the temperature range can be between 85°C and 100°C, and this is not limited.

[0117] For example, Figure 6 A temperature curve diagram of another thermal printing method provided in an embodiment of the present application, such as Figure 6 As shown, it includes the temperature curves of the first pulse PA and the second pulse PB when the current line E is printed and the previous line D is not printed. Figure 6It can be seen that since the previous line D is not printed, the true value of the previous line D is "0", so the current printing temperature is lower than the preset temperature range. When printing the current line E, E = 1, PA = E = 1,

[0118] For example, Figure 7 A temperature curve diagram of another thermal printing method provided in an embodiment of the present application, such as Figure 7 As shown, it includes a temperature curve diagram of the first pulse PA when the current line is printed and the previous line is also printed. Figure 7 It can be seen that, since the previous line is also printed, when the current line is printed, the current printing temperature is still within the preset temperature range.

[0119] For example, Figure 8 A temperature curve diagram of another thermal printing method provided in an embodiment of the present application, such as Figure 8 As shown, it is a temperature curve diagram of the third pulse PC when the current line and the previous line are not printed and the next line needs to be printed.
