[0002] In related technologies, when printing label content using a label printer, the heating time or heating power in the printing process needs to be manually adjusted to adapt to the color development characteristics of different types of label paper, so as to ensure the printing effect of the label paper.

[0071] In order to make the purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device. The specific meaning of the above terms in the present application can be understood by the person skilled in the art. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0073] In one embodiment, as shown in Figure 1 A control method of a label printer is specifically proposed, which can be implemented depending on a computer program and can be run on a control device of a label printer based on a von Neumann system. The computer program can be integrated in an application or run as an independent tool application.

[0074] Specifically, the control method of the label printer comprises:

[0075] S101, reading a pre-stored basic color development level parameter from a radio frequency identification chip configured on a label paper.

[0076] It can be understood that the label paper refers to consumables used by the label printer, which is used to print various label contents, such as text, numbers, pictures, one-dimensional bar codes, two-dimensional bar codes and the like.

[0077] The radio frequency identification chip refers to a micro wireless transceiver mainly composed of an internal antenna and a chip based on radio frequency identification technology.

[0078] The basic color development level parameter refers to a level parameter for characterizing the color development characteristics of the label paper. Optionally, the basic color development level parameter can be a level parameter positively correlated with the color development difficulty of the label paper, for example, for the label paper with greater color development difficulty, the corresponding basic color development level parameter is a parameter with greater level value, and for the label paper with smaller color development difficulty, the corresponding basic color development level parameter is a parameter with smaller level value.

[0079] In some embodiments, step S101 is performed, which can specifically be: the label printer performs data communication processing with the radio frequency identification chip configured on the label paper through the radio frequency identification module, and obtains the pre-stored basic color development level parameter in the radio frequency identification chip. It can be understood that the basic color development level parameter can be written into the radio frequency identification chip corresponding to the label paper during the production process of the label paper.

[0080] Optionally, the label printer can read the pre-stored basic color development level parameter from the radio frequency identification chip when detecting newly loaded label paper.

[0081] Optionally, the label printer can read the pre-stored basic color development level parameter from the radio frequency identification chip when receiving a print instruction for a print task.

[0082] S102, determining a target heating parameter according to the basic color development level parameter, and performing the print task according to the target heating parameter.

[0083] It can be understood that the target heating parameter refers to a parameter used to control and adjust the heating process of the label printer. Specifically, the target heating parameter can include at least one of a heating time and a heating power. The heating time refers to the duration required for the heating element of the label printer to reach a certain working temperature from starting heating. The heating power refers to the power of the heating element of the label printer during the heating process, and the heating power determines the heating capacity of the heating element.

[0084] In some embodiments, step S102 is performed, which can specifically be: obtaining a heating parameter mapping table, querying the target heating parameter corresponding to the basic color development level parameter from the heating parameter mapping table, and performing the print task according to the target heating parameter.

[0085] It can be understood that the above-mentioned heating parameter mapping table can store at least one basic color development level parameter and the heating parameter corresponding to each basic color development level parameter. For example, the heating parameter mapping table can include at least one basic color development level parameter and the heating time corresponding to each basic color development level parameter, and / or at least one basic color development level parameter and the heating power corresponding to each basic color development level parameter. Since label papers of different materials have different color development characteristics, some materials of label paper are difficult to develop color, and therefore a longer heating time or a larger heating power is required to reach a certain working temperature. Therefore, according to expert experience, corresponding basic color development level parameters can be pre-configured for different label papers, and heating parameters adapted to the basic color development level parameters can be pre-configured, and the heating parameters and corresponding basic color development level parameters can be stored in the heating parameter mapping table. The heating parameter mapping table can be stored locally in the label printer, so as to facilitate the label printer to obtain in time.

[0086] Optionally, the printing task is performed according to the target heating parameter, specifically, in the printing process, the heating element is controlled to heat according to the target heating parameter, and the content on the label paper is printed using the heating element after heating.

[0087] The control method of the label printer provided by the embodiments of the present application reads the pre-stored basic color development level parameter from the radio frequency identification chip arranged on the label paper, determines the target heating parameter according to the basic color development level parameter, and then performs the printing task according to the target heating parameter. In this way, by reading the basic color development level parameter of the label paper from the radio frequency identification chip, the heating parameter suitable for the label paper can be automatically determined according to the color development level of different label papers, so that the printing task is performed using the heating parameter suitable for different label papers, without the need for manual setting of the heating parameter by the user. Therefore, not only the printing quality can be ensured, but also the manual setting operation in the printing process can be simplified.

[0088] Please refer to Figure 2 The embodiments of the present application provide another flowchart of the control method of the label printer.

[0089] Specifically, the control method of the label printer comprises:

[0090] S201, reading a pre-stored basic color development level parameter from a radio frequency identification chip arranged on a label paper reel.

[0091] The basic color development level parameter is determined based on the material type and color development characteristics of the label paper.

[0092] It can be understood that the color development characteristics of the label paper refer to the characteristics for characterizing the color reduction ability of the label paper. Specifically, the color development characteristics can include surface smoothness, ink absorption, coating type and the like.

[0093] The level represented by the basic color development level parameter can be represented by a number, for example, 10 integers in 1-10 can be used to represent 10 levels, and when the value of the basic color development level parameter is larger, it can represent that the color development difficulty of the label paper is greater.

[0094] Optionally, the basic color development level parameter can be determined based on the material type and color development characteristics of the label paper in the process of producing the label paper, and then the basic color development level parameter is written into the radio frequency identification chip corresponding to the label paper, and the radio frequency identification chip is arranged in the label paper reel.

[0095] In step S201, the label printer is provided with a radio frequency identification module, and the label printer identifies the radio frequency identification installed on the label paper reel through the radio frequency identification module to obtain the pre-stored basic color development level parameter.

[0096] In step S202, the target heating parameter is determined according to the basic color development level parameter, and the printing task is performed according to the target heating parameter.

[0097] Specifically, the implementation of step S202 can refer to the description of the related part in the embodiment shown in Figure 1 The description of the related part in the embodiment shown in

[0098] In the control method of the label printer provided in the embodiments of the present application, the pre-stored basic color development level parameter is read from the radio frequency identification chip installed on the label paper reel, the target heating parameter is determined according to the basic color development level parameter, and the printing task is performed according to the target heating parameter. In this way, the basic color development level parameter is read from the radio frequency identification chip installed on the label paper reel, which simplifies the process of obtaining the basic color development level parameter by the label printer. Then, the heating parameter suitable for the label paper is automatically determined according to the color development level of the different label papers, and the printing task is performed by using the heating parameter suitable for the different label papers without manual setting of the heating parameter by the user. Therefore, the printing quality can be ensured, and the manual setting operation in the printing process is simplified.

[0099] Please refer to Figure 3 Another flowchart of the control method of the label printer is provided in the embodiments of the present application.

[0100] Specifically, the control method of the label printer comprises:

[0101] In step S301, when it is detected that the label paper is first loaded into the label printer, the pre-stored basic color development level parameter is read from the radio frequency identification chip configured on the label paper through the built-in radio frequency identification module.

[0102] In step S301, when it is detected that the label paper is loaded into the label printer, the label printer can identify the radio frequency identification chip configured on the label paper through the radio frequency identification module to obtain the model identification of the label paper. If the model identification is detected for the first time, it can be determined that the label paper is first loaded into the label printer, and then the pre-stored basic color development level parameter is read from the radio frequency identification chip configured on the label paper through the built-in radio frequency identification module.

[0103] Optionally, after the basic color development level parameter corresponding to the label paper is read, the mapping relationship between the model identification of the label paper and the basic color development level parameter can be saved, so that the basic color development level parameter can be directly obtained from the mapping relationship when the label paper is detected to be loaded into the label printer again in the future.

[0104] S302, determine the target heating parameter according to the basic color development level parameter, and execute the printing task according to the target heating parameter.

[0105] The implementation of step S302 can refer to the description of the related part in the embodiment shown in Figure 1 The implementation of step S302 can refer to the description of the related part in the embodiment shown in

[0106] In the control method of the label printer provided in the embodiments of the present application, when it is detected that the label paper is first loaded into the label printer, the pre-stored basic color development level parameter is read from the radio frequency identification chip configured on the label paper through the built-in radio frequency identification module, the target heating parameter is determined according to the basic color development level parameter, and the printing task is executed according to the target heating parameter. Therefore, when it is detected that the label paper is first loaded, the basic color development level parameter is read from the radio frequency identification chip, and it is not necessary to repeatedly read the basic color development level parameter from the radio frequency identification chip when the label paper is repeatedly loaded, so that the process of obtaining the basic color development level parameter by the label printer is simplified. Then, the heating parameter suitable for the label paper is automatically determined according to the color development level of different label papers, so that the printing task is executed by using the heating parameter suitable for different label papers, without the need for manual setting of the heating parameter by the user. Therefore, not only the printing quality can be ensured, but also the manual setting operation in the printing process is simplified.

[0107] Please refer to Figure 4 The embodiments of the present application provide another flowchart of the control method of the label printer.

[0108] Specifically, the control method of the label printer comprises the following steps.

[0109] S401, read the pre-stored basic color development level parameter from the radio frequency identification chip configured on the label paper.

[0110] The implementation of step S401 can refer to the description of the related part in the embodiment shown in Figure 1 The implementation of step S401 can refer to the description of the related part in the embodiment shown in

[0111] S402, obtain the basic heating parameter corresponding to the basic color development level parameter.

[0112] In some embodiments, step S401 can be specifically implemented as follows: obtaining a basic heating parameter mapping table, and querying the basic heating parameter corresponding to the basic color development level parameter from the basic heating parameter mapping table.

[0113] It can be understood that the above basic heating parameter mapping table can store at least one basic color development level parameter and the basic heating parameter corresponding to each basic color development level parameter. For example, the basic heating parameter mapping table can include at least one basic color development level parameter and the basic heating time corresponding to each basic color development level parameter, and / or at least one basic color development level parameter and the basic heating power corresponding to each basic color development level parameter. Since different materials of label paper have different color development characteristics, some materials of label paper are difficult to develop color, and a longer heating time or a larger heating power is required to reach a certain working temperature, so the corresponding basic color development level parameter can be configured for different label paper according to expert experience in advance, and the basic heating parameter matched with the basic color development level parameter is configured in advance, and the basic heating parameter and the basic color development level parameter corresponding to the basic heating parameter are stored in the basic heating parameter mapping table. The basic heating parameter mapping table can be stored in the local label printer, so as to facilitate the label printer to obtain in time.

[0114] In S403, the printing environment temperature is obtained, and the environment compensation coefficient is obtained.

[0115] The printing environment temperature refers to the temperature in the environment where the label printer is located.

[0116] In step S403, the printing environment temperature is obtained, which can be specifically: the label printer can collect the printing environment temperature through the built-in temperature and humidity sensor. Alternatively, the label printer can collect the printing environment temperature through the built-in temperature sensor. Alternatively, the label printer can send a temperature query instruction to the server, and the server determines the environment temperature of the location of the label printer through a weather query platform or weather query software. The label printer receives the environment temperature sent by the server based on the temperature query instruction, and determines the environment temperature as the printing environment temperature.

[0117] It can be understood that the environment compensation coefficient is a coefficient for adjusting the heating parameter at a certain temperature.

[0118] In step S403, the environment compensation coefficient is obtained, specifically, the label printer reads the environment compensation coefficient from the radio frequency identification chip. The environment compensation coefficient is determined based on the temperature sensitive characteristics of the label paper. For label papers of different material types, their corresponding temperature sensitive characteristics are different, and their corresponding color development characteristics are also different. Therefore, in the same printing environment with the same printing environment temperature, when the printing environment temperature is lower than a certain temperature, the environment compensation coefficients required by label papers of different material types are also different. It can be understood that the environment compensation coefficients corresponding to label papers of different material types can be pre-configured according to expert experience, and the environment compensation coefficients are written into the radio frequency identification chip corresponding to the label paper, so that the label printer can conveniently obtain the environment compensation coefficient when needed.

[0119] In step S404, the target heating parameter is obtained by performing parameter adjustment processing on the basis heating parameter according to the printing environment temperature and the environment compensation coefficient.

[0120] In some embodiments, taking the basis heating parameter including the basis heating time and the target heating parameter including the target heating time as an example, step S404 is performed, which can specifically include the following steps:

[0121] A1: obtaining a preset environment temperature;

[0122] A2: using a first calculation formula to perform parameter adjustment processing on the basis heating time according to the printing environment temperature, the environment compensation coefficient and the preset environment temperature to obtain the target heating time;

[0123] The first calculation formula satisfies the following formula:

[0124] t=t0[1+K×(T2-T1)]

[0125] The t represents the target heating time, the t0 represents the basis heating time, the K represents the environment compensation coefficient, the T1 represents the printing environment temperature, and the T2 represents the preset environment temperature.

[0126] In step A1, the preset environment temperature refers to a temperature constant set according to actual implementation requirements. For example, the room temperature is between 20-25 degrees Celsius, and the preset environment temperature can be set to 20 degrees Celsius, 21 degrees Celsius, 22 degrees Celsius, 23 degrees Celsius, 24 degrees Celsius or 25 degrees Celsius according to actual implementation requirements. The preset environment temperature is obtained, specifically, the preset environment temperature is obtained from a local parameter configuration file.

[0127] In step A2, for example, for a label paper with a material of thermal paper, the environmental compensation coefficient K can be set as 0.003, and the first calculation formula can be understood as: when the printing environment temperature is lower than the preset environment temperature, the heating time is increased by 0.3% for each 1 degree Celsius.

[0128] Optionally, after step S404 is performed, the method of the embodiments of the present application further includes: if the target heating time is greater than the preset heating time, outputting a heating warning.

[0129] It can be understood that the preset heating time can be set according to implementation requirements.

[0130] It can be understood that the outputting of the heating warning can include at least one of the following implementation manners: controlling a preset indicator light to flash; outputting a preset heating time overrun prompt sound; displaying a preset heating time overrun prompt text through a display screen; and displaying a preset heating time overrun prompt pattern through the display screen.

[0131] Thus, when it is detected that the target heating time is greater than the preset heating time, the user is reminded to adjust the heating time by outputting the heating warning, so as to avoid damage to the print head caused by too long heating time.

[0132] In still other embodiments, taking the case that the basic heating parameter includes a basic heating power and the target heating parameter includes a target heating power as an example, step S404 can specifically include the following steps:

[0133] B1: obtaining a preset environment temperature;

[0134] B2: performing parameter adjustment processing on the basic heating power to obtain the target heating power according to the printing environment temperature, the environmental compensation coefficient and the preset environment temperature by using a second calculation formula;

[0135] wherein the second calculation formula satisfies the following formula:

[0136] P=P0[1+K×(T2-T1)]

[0137] P represents the target heating power, P0 represents the basic heating power, K represents the environmental compensation coefficient, T1 represents the printing environment temperature, and T2 represents the preset environment temperature.

[0138] In step B1, the preset environment temperature refers to a temperature constant set according to actual implementation requirements. For example, room temperature is between 20-25 degrees Celsius, and the preset environment temperature can be set to 20 degrees Celsius, 21 degrees Celsius, 22 degrees Celsius, 23 degrees Celsius, 24 degrees Celsius or 25 degrees Celsius according to actual implementation requirements. The preset environment temperature is obtained, which can be specifically obtained from a local parameter configuration file.

[0139] In step A2, for example, for label paper with thermal paper, the environmental compensation coefficient K can be set as a constant a, and the second calculation formula can be understood as: when the printing environment temperature is lower than the preset environment temperature, the heating power is increased by 100a% for every 1 degree Celsius.

[0140] S405, performing a printing task according to the target heating parameter.

[0141] In some embodiments, step S405 can be specifically performed as follows: controlling the heating element to heat according to the target heating time and / or the target heating power, so that the heating element reaches the preset working temperature to print the content of the label paper.

[0142] In the control method of the label printer provided in the embodiments of the present application, after reading the basic color development level parameter, the basic heating parameter corresponding to the basic color development level parameter is obtained, the printing environment temperature is obtained, and the environmental compensation coefficient is obtained. The target heating parameter is obtained by performing parameter adjustment processing on the basic heating parameter according to the printing environment temperature and the environmental compensation coefficient, and the printing task is performed according to the target heating parameter. Therefore, by obtaining the printing environment temperature and the environmental compensation coefficient, the basic heating parameter corresponding to the basic color development level parameter is flexibly adjusted according to the printing environment temperature and the environmental compensation coefficient, and the printing task is performed using the adjusted heating parameter. Not only can it avoid color development abnormalities of label paper with certain materials due to temperature difference, but also can ensure printing quality, and does not need manual setting of heating parameters, simplifying manual setting operation in the printing process.

[0143] Please refer to Figure 5 The embodiments of the present application provide another flowchart of a control method of a label printer.

[0144] Specifically, the control method of the label printer comprises:

[0146] S502, determining the target heating parameter according to the basic color development level parameter, and performing the printing task according to the target heating parameter.

[0147] Specifically, the implementation of steps S501 and S502 can refer to the description of the related parts in the embodiments shown in the description of the first aspect, which will not be repeated here. Figure 1 The description of the related parts in the embodiments shown in the description of the first aspect will not be repeated here.

[0148] S503, obtaining a color rendering level modification operation input by a user, and determining a reference color rendering level parameter corresponding to the color rendering level modification operation.

[0149] The color rendering level modification operation refers to an operation of modifying the basic color rendering level parameter by the user.

[0150] In step S503, obtaining the color rendering level modification operation input by the user can be specifically: obtaining the color rendering level modification operation input by the user based on a color rendering level adjustment control in the label printer. The color rendering level adjustment control can be a physical entity control configured in the label printer, or a virtual control displayed on the display screen of the label printer. In some embodiments, obtaining the color rendering level modification operation input by the user can also be: obtaining the color rendering level modification operation input by the user through the user terminal. For example, the user terminal can be installed with an operation software for controlling the label printer. The operation software can be used for operations such as control, configuration, and management of the label printer. The operation software can display a color rendering level configuration interface. When the user inputs the color rendering level modification operation on the color rendering level configuration interface, the user terminal can forward the color rendering level modification operation to the label printer.

[0151] In step S503, determining the reference color rendering level parameter corresponding to the color rendering level modification operation can be specifically: determining the modified color rendering level parameter indicated by the color rendering level modification operation as the reference color rendering level parameter.

[0152] S504, determining a target offset based on the reference color rendering level parameter and the basic color rendering level parameter.

[0153] In step S504, the difference between the first level value of the reference color rendering level parameter and the second level value of the basic color rendering level parameter can be calculated to obtain the target offset.

[0154] S505, calculating the sum of one-half of the target offset and the basic display level parameter, and performing parameter update processing on the basic color rendering level parameter based on the sum to obtain a target color rendering level parameter.

[0155] In step S505, the base color rendering level parameter can be modified to a sum of one half of the target offset and the base display level parameter to obtain a target color rendering level parameter with a level value of the sum. Specifically, the base color rendering level parameter can be stored in a parameter mapping table, and the base color rendering level parameter in the parameter mapping table can be modified to the target color rendering level parameter with a level value of the sum.

[0156] In the control method of the label printer provided in the present application, after reading the base color rendering level parameter, a target heating parameter is determined according to the base color rendering level parameter, a printing task is performed according to the target heating parameter, a color rendering level modification operation input by a user is obtained, a reference color rendering level parameter corresponding to the color rendering level modification operation is determined, a target offset is determined according to the reference color rendering level parameter and the base color rendering level parameter, a sum of one half of the target offset and the base display level parameter is calculated, and a parameter updating process is performed on the base color rendering level parameter based on the sum to obtain a target color rendering level parameter. Thus, the embodiments of the present application not only can automatically perform a printing task using a heating parameter adapted to different label papers, but also can optimize the originally set base color rendering level parameter by integrating the experience of the user setting the color rendering level, so that the embodiments of the present application not only can guarantee the printing quality of the present printing task and simplify the manual setting operation in the printing process, but also can optimize the color rendering level parameter by integrating the experience of the user, so as to perform a printing task according to the optimized color rendering level parameter in the subsequent printing process of the label paper to further improve the printing quality of the subsequent label paper.

[0157] Please refer to Figure 6 Another flowchart of the control method of the label printer is provided for the embodiments of the present application.

[0158] Specifically, the control method of the label printer comprises:

[0159] S601, reading a pre-stored base color rendering level parameter from a radio frequency identification chip configured on the label paper.

[0160] S602, determining a target heating parameter according to the base color rendering level parameter, and performing a printing task according to the target heating parameter.

[0161] Specifically, the implementation manners of steps S601 and S602 can refer to the descriptions of the related parts in the embodiments shown in Figure 1 The descriptions of the related parts in the embodiments shown in

[0162] S603, capturing a printing content image through a camera.

[0163] It can be understood that the printing content image refers to an image of the label paper printed with the printing content captured by the label printer.

[0164] In step S603, the label printer enables the camera to capture the printed content image of the page paper after completing the printing of the printed content in the process of executing the printing task. It can be understood that a printing task can complete the printing of multiple page papers, and therefore the camera can capture the printed content images corresponding to the multiple page papers respectively.

[0165] S604, the clarity evaluation model is used to evaluate the printed content image to obtain a target clarity score.

[0166] In step S604, the label printer can be locally configured with a pre-trained printing evaluation model. Taking the printed content as text as an example, the principle of obtaining the target clarity score by using the printing evaluation model can be: extracting text edge features and text texture features in the printed content image through a preset convolution layer of the printing evaluation model, extracting key features of the text edge features and the text texture features through a preset pooling layer of the printing evaluation model to obtain text key features, and obtaining the target clarity score by linear combination processing and activation function conversion processing of the text key features through a preset full connection layer of the printing evaluation model. It can be understood that the parameters and weights in the preset convolution layer, the preset pooling layer, and the preset full connection layer of the printing evaluation model can be determined in the model training process.

[0167] It can be understood that the printing evaluation model can process multiple printed content images to obtain a target clarity score for each printed content image.

[0168] S605, determining a first clarity score less than the preset score in the target clarity score, and determining a target number of the first clarity score.

[0169] In step S605, the preset score can be set according to the implementation requirements. For example, the target clarity score output by the printing evaluation model ranges from 0 to 100, and the preset score can be set to 90.

[0170] S606, if the target number is greater than or equal to a preset number of times, determining the difference between the preset score and the first clarity score, determining the first product of the difference and a first preset value, and determining the first product as the heating time adjustment coefficient.

[0171] In step S606, the preset score is used as the minuend, and the first clarity score is used as the subtrahend to calculate the difference between the preset score and the first clarity score. The first clarity score is less than the preset score, and the difference is a positive number.

[0172] In step S606, the first preset value can be set according to the implementation requirements. For example, the first preset value can be set to 0.05.

[0173] S607, acquire the historical heating time corresponding to the label paper, determine a second product of the historical heating time and the heating time adjustment coefficient, determine a first sum of the second product and the historical heating time, and determine the first sum as the updated heating time corresponding to the label paper.

[0174] The historical heating time is a basic heating time corresponding to the basic color development level parameter, or the historical heating time is the corrected heating time.

[0175] It can be understood that the corrected heating time described above can refer to the heating time obtained by adjusting the basic heating time. For example, when the target heating parameter in S602 includes a target heating time, the corrected heating time can also be the target heating time.

[0176] S608, write the updated heating time into the radio frequency identification chip.

[0177] In step S608, the label printer can write the updated heating time into the radio frequency identification chip through the radio frequency identification module.

[0178] In the control method of the label printer provided in the present application, not only can the heating parameters suitable for different label papers be automatically adopted to perform the printing task, but also the user does not need to manually set the heating parameters. In addition, the printing evaluation model can be used to perform the clarity evaluation processing on the printing content image collected by the camera to obtain the target clarity score. Furthermore, the heating time is updated according to the target clarity score to obtain the updated heating time corresponding to the label paper, and the updated heating time is written into the radio frequency identification chip. Therefore, the embodiments of the present application not only can guarantee the printing quality of the present printing task and simplify the manual setting operation in the printing process, but also can write the updated heating time determined based on the clarity score into the radio frequency identification chip to realize the automatic update of the label paper parameters, so as to cope with the influence of the aging of the label paper material or the aging change of the printer on the printing process.

[0183] Specifically, steps S701 and S702 can refer to Figure 1The description of the relevant parts of the illustrated embodiments will not be repeated here.

[0184] S703, when the basic color rendering level parameter is greater than or equal to the preset color rendering level, starting the double-pulse heating mode, and executing the printing task according to the target heating parameter in the double-pulse heating mode.

[0185] It can be understood that the double-pulse heating mode refers to a heating mode in which the heating power of the heating element is adjusted by using two pulse signals.

[0186] In some embodiments, the target heating parameter obtained by step S702 can include a target heating time, and then step S703 is executed, which can specifically include: when the basic color rendering level parameter is greater than or equal to the preset color rendering level, obtaining a reference heating power corresponding to the heating element, starting the double-pulse heating mode, the double-pulse heating mode including a first power and a second power determined based on the reference heating power, the first power being greater than the reference heating power, and the second power being less than the reference heating power, preheating the heating element according to the first power, determining a remaining heating time other than a preset time based on the target heating time, after the preheating time is equal to the preset time, continuously heating the heating element using the second power within the remaining heating time, so that the heating element reaches a preset working temperature, and printing the content of the label paper. Wherein, the reference heating power can be the rated working power of the heating element; the first power and the second power can be set based on expert experience; and the sum of the preset time and the remaining heating time can be the target heating time.

[0187] In some embodiments, the double-pulse heating mode includes a first heating power and a second heating power, the first heating power is greater than the second heating power, and the printing task is executed according to the target heating parameter in the double-pulse heating mode. Specifically, the preheating process can be performed according to the target heating parameter by using the first heating power, and after the preheating time length is equal to the preset time length, the printing task can be executed according to the target heating parameter by using the second heating power. In this embodiment, the target heating parameter obtained by step S702 can include a target heating time and a target heating power. Specifically, the first heating power can be a first multiple of the base power, and the second heating power can be a second multiple of the base power. The preheating process is performed according to the target heating parameter by using the first heating power, and the printing task is executed according to the target heating parameter by using the second heating power. It can be understood that the target heating time and the target heating power are determined in the target heating parameter, the target heating power in the target heating parameter is determined as the base power, the remaining heating time other than the preset time length is determined based on the target heating time, the first multiple of the base power is determined as the first heating power, the second multiple of the base power is determined as the second heating power, the heating element is preheated by using the first heating power in the first time interval of the target heating time, and after the preheating time length is equal to the preset time length, the heating element is continuously heated by using the second heating power in the remaining heating time, so that the heating element reaches the preset working temperature to print the content of the label paper. The first multiple and the second multiple can be set based on expert experience. For example, the first multiple can be set to 1.2, and the second multiple can be set to 0.8. The sum of the preset time length and the remaining heating time can be the target heating time.

[0188] In the control method of the label printer provided in the embodiments of the present application, after the base color development level parameter is read from the radio frequency identification chip, the target heating parameter is determined according to the base color development level parameter, when the base color development level parameter is greater than or equal to the preset color development level, the double-pulse heating mode is started, and the printing task is executed according to the target heating parameter in the double-pulse heating mode. Therefore, not only can the heating parameter suitable for different label papers be automatically used to execute the printing task, but also the user does not need to manually set the heating parameter, and the double-pulse heating mode can be automatically started to execute the printing task when the color development level parameter is high. Therefore, the embodiments of the present application not only can ensure the printing quality of the current printing task and simplify the manual setting operation in the printing process, but also can solve the problem of uneven color development caused by slow heat conduction of some materials (such as high-density synthetic materials).

[0198] In step S804, the second preset value can be set according to an expert, and the basic heating time can be the heating time in the target heating parameter; the dynamic correction heating time is represented by t2, the second preset value is represented by b, and the printing speed is represented by v. The calculation formula of the dynamic correction heating time can adopt the following expression:

[0199] t2=t0×(1+b×v)

In addition, the printing speed is determined in the printing process, the heating time is dynamically corrected according to the printing speed, and the printing task is performed according to the corrected heating time. Therefore, the printing quality of the printing task can be ensured, the manual setting operation in the printing process can be simplified, and the problem of insufficient color development caused by the shortening of the contact time in high-speed printing can be solved.
