The ESC instruction set is usually used for cash register receipt printing, the CPCL instruction set is usually used for label printing, and private protocols are usually used for APP printing labels.

The printing devices in the related art usually communicate based on a single protocol.

Therefore, the present application provides a data printing method to solve the technical problem that the printing devices in the above-mentioned related art that communicate based on a single protocol are difficult to meet complex user interaction needs.

[0082] Please refer to the following Figure 1 , which exemplarily shows a structural diagram of a data printing system provided by an embodiment of the present application. Figure 1 As shown, the system includes a printing device 110 and a terminal device 120, and the printing device 110 and the terminal device 120 are communicatively connected, for example, through a wired or wireless network connection, or through a parallel interface connection.

[0088] Optionally, the data to be printed is content that needs to be printed on a print medium, and the data to be printed may include documents, images, or other content that needs to be output through a printing device.

[0089] Optionally, the data to be printed may be determined by the user, and the user may provide the data to be printed in different ways, such as uploading the data to be printed by means of a computer, a mobile phone, a cloud storage, etc.

[0092] Optionally, the target protocol processing function can be any one of the above multiple protocol processing functions.

[0093] An exemplary embodiment of the present application provides a data printing method. This data printing method can be applied to the above printing device. For details, please refer to Figure 2 , which exemplarily shows a flowchart of a data printing method provided by an embodiment of the present application. As Figure 2 shown, this data printing method includes the following S21 - S24:

[0094] S21. Obtain the data to be printed.

[0095] In some embodiments, the data to be printed is the content that needs to be printed on a printing medium (such as paper), and the data to be printed can include documents, images, or other content that needs to be output by the printing device.

[0096] In some embodiments, the data to be printed can be determined by the user, and the user can provide the data to be printed in different ways, such as uploading the data to be printed through a computer, mobile phone, cloud storage, etc.

[0097] In some embodiments, in S21, the above-mentioned obtaining the data to be printed includes:

[0098] Receiving the external data to be printed through any one of the following ways: Bluetooth, USB.

[0099] By supporting multiple connection methods, users can select a more suitable connection method according to different needs and scenarios and upload the data to be printed to the printing device. For example, Bluetooth is suitable for convenient scenarios that require wireless connection, while USB is suitable for scenarios that require high data transfer rate and stable connection. The flexible connection method can meet the needs of different users and improve the usability and flexibility of the printing device.

[0100] S22. Determine the target printing mode in which the above printing device is currently located, and the target printing mode is any one of multiple preset printing modes.

[0101] In some embodiments, the plurality of preset printing modes include at least: a first printing mode and a second printing mode, wherein the first printing mode is used to print ticket information, and the second printing mode is used to print label information.

[0102] The printing device may pre-define a plurality of different printing modes to adapt to different types of printing tasks. Each mode may perform corresponding printing processing according to different printing requirements (such as quality, speed, paper size, etc.).

[0103] In some embodiments, the ticket information may include information such as receipts, invoices, slips, etc. For example, a merchant may print a sales invoice through a first printing mode of a printing device.

[0104] In some embodiments, label information refers to identification information attached to products, articles, documents, etc., usually a card made of paper or other materials, used to provide key information related to the article to users or staff. Optionally, the label information may include one or more of the product name, barcode / QR code, production date / expiration date, batch number, price information, etc.

[0105] By providing multiple print modes, the printing device can adapt to various printing needs. Each print mode can be optimized according to specific task requirements. For example, ticket information may require a higher print speed, while label information printing may require a high resolution to ensure clear and readable barcodes. By defining different modes for each task, performance can be customized to improve printing results and efficiency.

[0106] S23. Determine a corresponding target protocol processing function based on the target printing mode.

[0107] In some embodiments, the printing device may support multiple protocol processing functions, including but not limited to: CPCL instruction set, ESC instruction set, and enterprise-proprietary protocol processing functions.

[0108] In some embodiments, the target protocol processing function may be any one of the above-mentioned multiple protocol processing functions.

[0109] S24, performing printing processing on the data to be printed based on the target protocol processing function.

[0110] The above-mentioned multiple protocol processing functions can be used for different printing scenarios or functions. The printing device can perform printing processing on the data to be printed according to the target protocol processing function corresponding to the data to be printed, so that the data to be printed is processed according to the correct format and protocol.

[0111] In some embodiments, the printing process may include converting the data to be printed into instructions that can be understood and executed by the printing device, and outputting the final printing result through the printing device.

[0112] The embodiment of the present application obtains the data to be printed; determines the target printing mode currently in the above-mentioned printing device based on the above-mentioned data to be printed, and the above-mentioned target printing mode is any one of multiple preset printing modes; determines the corresponding target protocol processing function based on the above-mentioned target printing mode; and performs printing processing on the above-mentioned data to be printed based on the above-mentioned target protocol processing function. Thus, the printing mode currently in the printing device is automatically identified through the data to be printed, and the corresponding protocol processing function can be used for targeted processing; the setting of multiple printing modes can enable the printing device to support multiple scenarios and meet different printing needs, avoiding the limitation that traditional printing devices only support a single protocol, and significantly improving the compatibility and operation flexibility of the printing device.

[0113] In some embodiments, in the above S22, determining the current target printing mode of the above printing device based on the above data to be printed includes S221-S222:

[0114] S221. Obtain sub-data of the data to be printed from a preset buffer, where the preset buffer is used to cache the data to be printed, and the sub-data includes mode identification information corresponding to the printing device.

[0115] In some embodiments, after receiving the data to be printed, the data to be printed may be cached in a preset buffer, which may be a ring buffer. The ring buffer is a storage structure that can be used to process the cache of received and sent data and can realize circular storage of data.

[0116] In some embodiments, the sub-data of the data to be printed may be 1 byte of data to be printed in the buffer.

[0117] That is to say, 1 byte of data is taken from the buffer for processing each time, and then the first frame header parsing stage is entered. The frame header is the beginning part of the data to be printed, and can represent basic information such as mode identification information and length of the data to be printed.

[0118] S222: Determine the target printing mode currently corresponding to the printing device based on the mode identification information in the sub-data.

[0119] In the first frame header parsing stage, the 1-byte sub-data extracted from the buffer can be parsed to obtain mode identification information in the sub-data, and the mode identification information in the sub-data is used to uniquely identify the corresponding printing mode.

[0120] In the embodiment of the present application, each time a byte of data is extracted from the buffer for parsing, the current target printing mode can be determined in real time, and then the corresponding processing protocol function is used for printing. As a result, the printing device can dynamically adapt to different printing requirements according to the received data to be printed, thereby improving printing efficiency and accuracy. In addition, the ring buffer provides an efficient storage mechanism that can continuously store and read data in a loop, which is very effective for processing continuous stream data, avoiding memory waste and reducing management complexity.

[0121] In some embodiments, in the above S23, the above determination of the corresponding target protocol processing function based on the above target printing mode includes S231-S233:

[0122] S231. When the target printing mode is the first printing mode, use the ESC instruction set as the target protocol processing function.

[0123] Among them, the ESC instruction set is a standardized instruction set for controlling printers, which is widely used in dot matrix printers and thermal printers. The ESC instruction set can provide fast, simple and efficient text processing and formatting functions, while supporting efficient paper management (such as paper cutting, paper changing, etc.), which can meet the needs of high-frequency ticket printing in commercial scenarios. Therefore, when the target printing mode is the first printing mode for printing ticket information, the ESC instruction set can be used for printing operations.

[0124] In some embodiments, when it is determined that the current target printing mode is the first printing mode, the ESC instruction set processing function can be directly determined and the current state machine can be exited without performing subsequent frame header, data frame, and frame tail processing procedures of the private protocol.

[0125] S232. When the target printing mode is the second printing mode, if the frame header data of the sub-data hits the characteristic byte of the ESC instruction set, the ESC instruction set is used as the target protocol processing function.

[0126] The characteristic byte is the header information in the data transmission, which can be used to identify the type of processing protocol function.

[0127] In some embodiments, the characteristic byte of the ESC instruction set may be 0x1B, i.e., a character (ESC character) with an ASCII code of 27. When the target printing mode is the second printing mode, it may be determined whether the frame header of the sub-data includes 0x1B (ESC character). If so, it is determined that the frame header data of the sub-data hits the characteristic byte of the ESC instruction set; if not, it is determined that the frame header data of the sub-data does not hit the characteristic byte of the ESC instruction set.

[0128] The ESC instruction set defines a set of commands and instructions that can control the behavior of the printer, such as text formatting, paper control, printing start and end, etc. Since the ESC instruction set is very commonly used in printing devices, when the frame header data matches the characteristic byte of the ESC instruction set, it means that the sub-data conforms to the format and specification of the ESC instruction set. By matching the characteristic byte to confirm that it is the ESC instruction set, the relevant processing function can be directly called, avoiding complex protocol parsing steps and improving the processing efficiency of the system.

[0129] S233. When the target printing mode is the second printing mode, if the frame header data of the sub-data hits the characteristic byte of the CPCL instruction set, the CPCL instruction set is used as the target protocol processing function.

[0130] CPCL is a language used to control printer behavior and is widely used in barcode printers and label printers. CPCL instruction set provides users with a flexible printing instruction set to define various parameters of printing tasks, such as print format, font style, image processing, and print speed.

[0131] In some embodiments, the characteristic byte of the CPCL instruction set can be "!" (exclamation mark and space). When the above-mentioned target printing mode is the above-mentioned second printing mode, it can be determined whether the first two bytes of the frame header of the sub-data are an exclamation mark and a space. If so, it is determined that the frame header data of the sub-data hits the characteristic bytes of the above-mentioned CPCL instruction set; if not, it is determined that the frame header data of the sub-data does not hit the characteristic bytes of the above-mentioned CPCL instruction set.

[0132] In the communication protocol, the frame header usually contains some key information to identify the data type and protocol type. The feature byte is a part of the sub-data, which is used to indicate that the sub-data follows a specific protocol specification. If the frame header data hits the feature byte of the CPCL instruction set, it means that the sub-data conforms to the format and structure of the CPCL protocol. By matching the protocol through the feature byte, it can be automatically identified that the data to be printed belongs to the CPCL protocol without the need for additional parsing steps, and then the CPCL protocol processing function can be directly called to process the data, simplifying the protocol parsing process and improving data processing efficiency. In addition, by using the CPCL instruction set, the printing device can accurately control the printing format, image, font, barcode and other contents to ensure that the output results match the user's needs, thereby avoiding printing errors or equipment failures.

[0133] In the embodiment of the present application, the printing device can support multiple protocol processing functions. Therefore, the corresponding protocol processing functions can be flexibly used according to different printing tasks or device configurations, so that the printing device can adapt to a wider range of applications and is not limited to a certain instruction set or protocol, thereby improving the compatibility and stability of the printer device. In addition, if new printing modes or protocol processing functions need to be added in the future, it is only necessary to simply add new protocol processing functions and mode mappings, so that new printing modes and protocol processing functions can be easily supported in subsequent updates, effectively improving the scalability of the printing device.

[0134] In some embodiments, in the above S23, the above determination of the corresponding target protocol processing function based on the above target printing mode further includes S234:

[0135] When the target printing mode is the second printing mode, if the frame header data of the sub-data does not hit the characteristic byte of the ESC instruction set and does not hit the characteristic byte of the CPCL instruction set, the preset private protocol is used as the target protocol processing function.

[0136] In some embodiments, the enterprise private protocol can be a protocol customized for the printing equipment of certain enterprises or organizations according to their specific needs. Different from standard protocols (such as CPCL, ESC, etc.), the enterprise private protocol is usually proprietary and can only be used in the printing equipment and systems of the enterprise or its partners.

[0137] The above-mentioned ESC and CPCL are known standard printing protocols. When the frame header data of the sub-data does not hit the characteristic bytes of these standard protocols, it can be considered that the sub-data may come from different devices or use different protocol formats. If not processed, it may cause protocol parsing failure or conflict, thus affecting the entire printing process. By introducing a private protocol as a fallback solution, data processing can continue when encountering unknown or non-standard protocol data, without crashing or stopping due to unrecognizable protocols. This fault-tolerant mechanism improves the stability and robustness of the printing process.

[0138] Figure 3 A flowchart of a method for determining a target protocol processing function provided by an exemplary embodiment of the present application is shown as follows: Figure 3 As shown, the method for determining the target protocol processing function includes S301-S309:

[0139] S301, obtaining data to be printed.

[0140] S302, obtaining sub-data of the data to be printed from a preset buffer.

[0141] S303, determine whether the target printing mode is the first printing mode. If yes, execute S304; if no, execute S305.

[0142] S304: Use the ESC instruction set as the target protocol processing function.

[0143] S305: Determine that the target printing mode is the second printing mode.

[0144] S306: Determine whether the frame header data of the sub-data matches the characteristic byte of the ESC instruction set. If yes, execute S304; if no, execute S307.

[0145] S307, determine whether the frame header data of the sub-data matches the characteristic byte of the CPCL instruction set. If yes, execute S308; if no, execute S309.

[0146] S308. Use the CPCL instruction set as the target protocol processing function.

[0147] S309: Use the preset private protocol as the target protocol processing function.

[0148] Optionally, the specific steps of S301-S309 are consistent with the specific steps of S21-S23 described above, and are not repeated here.

[0149] In the embodiment of the present application, by judging whether the frame header data conforms to the characteristic bytes of ESC or CPCL, different printing protocols can be automatically identified and adapted. If the frame header of the sub-data does not hit the characteristic bytes of any standard protocol instruction set (i.e., it does not hit ESC or CPCL), it can fall back to using the enterprise's private protocol for processing. This mechanism can ensure that the system can work normally under a variety of different protocols without relying on external intervention, thereby improving the stability and robustness of the printing process.

[0150] In some embodiments, in the above S24, the above printing process of the above data to be printed based on the above target protocol processing function includes S241-S242:

[0151] S241. Parse the data to be printed based on the target protocol processing function to obtain a printing control instruction corresponding to the data to be printed.

[0152] The target protocol processing function can be used to parse the data to be printed and understand the instructions and commands in the data to be printed. The printing control instructions corresponding to the data to be printed are instructions for controlling the specific behavior of the printing device.

[0153] S242: Print the data to be printed based on the print control instruction.

[0154] In some embodiments, when the target printing mode is the first printing mode, the printing control instruction at least includes: a start instruction, a pre-feed instruction, a printing instruction, a heating instruction and a printing end instruction.

[0155] Among them, the start instruction is an instruction to start the printing device or printing function; the pre-paper feeding instruction is an instruction to control the printing device to feed paper to a specified position so as to start printing; the printing instruction is an instruction to actually start printing the above-mentioned data to be printed; the heating instruction can be an instruction to control the printing device to heat; the printing end instruction is an instruction to indicate that the printing operation is completed and ended.

[0156] In some embodiments, when the target printing mode is the first printing mode, the printing control instructions include at least: a start instruction, a label paper feeding instruction, a pre-feeding instruction, a printing instruction, a heating instruction, a label paper positioning instruction and a printing end instruction.

[0157] Among them, the label paper feeding instruction is an instruction to control the printing device to rewind the label paper from near the print head. Specifically, it can be to return the label paper to the appropriate starting position when the printing device is printing, so as to print the next label or complete the label printing process; the label paper positioning instruction is an instruction for accurately positioning the position of the label paper in the printing device, which can make the label paper in the correct position under the print head, thereby ensuring that the printed content of the label matches the actual position of the label paper.

[0158] The combination of the above-mentioned different instructions makes the entire printing process more precise and efficient. Each step is controlled in an orderly manner to avoid possible errors or omissions. The precise label paper positioning, heating control and printing instructions make the printed content clearer and more accurate. Pre-feed instructions, paper return instructions, etc. are used to avoid paper waste and label misalignment, thereby improving the utilization rate of label paper resources.

[0159] Figure 4 A flowchart of a data printing method provided by an exemplary embodiment of the present application is shown as follows: Figure 4 As shown, the data printing method includes S401-S414:

[0160] S401: Determine whether the printing device is idle.

[0161] Optionally, the current status of the printing device can be obtained through relevant status query commands (such as the status query command of the printing device driver interface or the printer itself). These statuses usually include whether it is in an idle state, whether it is printing, whether an error or failure occurs, etc.

[0162] S402: Determine whether the target printing mode is the second printing mode. If yes, execute S403; if no, execute S410.

[0163] Optionally, when the printing mode of the printing device includes only the first printing mode and the second printing mode, if it is determined that the target printing mode is not the second printing mode, the target printing mode may be directly determined to be the first printing mode.

[0164] S403: Execute the start instruction.

[0165] S404, executing the label paper feeding instruction.

[0166] S405, executing the pre-paper feeding instruction.

[0167] S406: Execute the printing instruction.

[0168] S407, executing the heating instruction.

[0169] S408, executing the label paper positioning instruction.

[0170] S409, execute the print end instruction.

[0171] S410, executing the opening instruction.

[0172] S411, execute the pre-paper feeding instruction.

[0173] S412: Execute the printing instruction.

[0174] S413, executing the heating instruction.

[0175] S414, execute the print end instruction.

[0176] In the embodiment of the present application, different printing control instructions are set for different printing modes, so that the printing device can optimize processing for specific tasks and avoid unnecessary operations or redundant instructions, thereby optimizing the printing process, reducing the operating complexity of the printing device, improving printing efficiency, and making the printing process more intelligent and automated.

[0177] In some embodiments, the above method further includes S31-S32:

[0178] S31. Detecting a click operation on a preset button of the printing device based on a preset period.

[0179] In some embodiments, the preset button may be a specific button in the printing device, and the preset button may have at least one predefined function or trigger operation, for example, may include operations such as printing mode switching, etc. Optionally, the preset period may be 1 millisecond.

[0180] For example, the status of a preset button can be periodically checked (every 1 ms) in the interrupt function of the system tick timer Systick, and it can be determined whether the preset button is pressed, lifted, or long-pressed through a basic debounce algorithm.

[0181] In some embodiments, for the detection of the click operation on the above-mentioned preset button, the above method further includes: when it is detected that the duration of the click on the above-mentioned preset button exceeds a preset duration, it is determined that a click operation on the above-mentioned preset button is detected.

[0182] In some embodiments, the above-mentioned preset duration is 300 milliseconds.

[0183] That is to say, if the time when the preset button is pressed exceeds the preset duration (e.g., 300 milliseconds), this pressing action can be considered a valid click operation rather than a short accidental touch or inadvertent press. Among them, the role of the preset duration is to distinguish between a long press and a short press.

[0184] By setting a preset duration such as 300 milliseconds, the printing device can distinguish between valid clicks and short accidental touches or inadvertent operations. This not only avoids mis-triggering but also improves the user experience, achieving a balance between response speed and accuracy, making the printing device more intelligent, stable, and better adapted to actual operation requirements.

[0185] S32. When it is detected that the click operation on the above-mentioned preset button meets the preset mode switching condition, switch the current target printing mode of the above-mentioned printing device and modify the corresponding mode identification information of the above-mentioned printing device.

[0186] In some embodiments, the above-mentioned preset mode switching condition is: the number of cycles of continuously detecting click operations on the above-mentioned preset button reaches a preset number threshold;

[0187] In some embodiments, the above-mentioned preset number threshold is 4. That is to say, if the preset button is continuously clicked 4 times, and each click lasts for more than 300 milliseconds, then it can be considered that this is a signal from the user requesting to switch the printing mode, and the mode switching is executed.

[0188] Figure 5 The flowchart of a printing mode switching method provided by an exemplary embodiment of the present application is as Figure 5 shown, and this printing mode switching method includes S501 - S507:

[0189] S501. Based on a preset period, determine whether it is detected that the duration of the click on the preset button exceeds the preset duration. If so, execute S502; if not, enter the next period and return to execute S501.

[0190] S502: Determine whether a click operation on a preset button is detected.

[0191] S503: Determine the number of cycles in which a click operation on a preset button is continuously detected.

[0192] S504: Determine whether the number of cycles in which the click operation on the preset button is detected continuously reaches the preset number threshold. If yes, execute S505; if no, enter the next cycle and return to execute S501.

[0193] S505: Determine the number of cycles in which a click operation on a preset button is continuously detected.

[0194] S506: Determine whether the detected click operation on the preset button satisfies the preset mode switching condition.

[0195] S507: Switch the current target printing mode of the printing device, and modify the mode identification information corresponding to the printing device.

[0196] Optionally, the specific steps of S501-S507 are consistent with the specific steps of S31-S32 described above, and are not repeated here.

[0197] In the embodiment of the present application, through continuous detection and threshold judgment, it is possible to have better fault tolerance for the user's unintentional or accidental clicking behavior, avoid interference with the printing device, and effectively improve the stability of the printing device during operation.

[0198] In actual application scenarios, enterprise private protocols can be used to meet the needs of APP to print multiple labels, use the ESC instruction set protocol to print receipts, and use the CPCL instruction set protocol to print labels. Specifically, for home use scenarios, labels can be printed through APP, and for corporate users (such as the express delivery industry, government construction, etc.), they can be printed through customized software based on the enterprise private protocol. For example, the enterprise can use the CPCL protocol to communicate with the printing device through secondary developed software. In addition, merchants such as cash registers can use the ESC instruction set protocol to communicate with the printing device through the cash register system.

[0199] This application implements mode switching for different application scenarios, avoiding users from purchasing different printing devices to meet multiple needs, and effectively improving the reusability and scalability of printing devices. By organically combining the needs of the enterprise and personal ends, the printing needs of different scenarios can be met on the same printing device, and different printing methods can be used according to different printing modes, thereby improving the response speed of data processing and printing processes.
