[0030] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 An embodiment of a method for implementing configurable electronic bill printing in an embodiment of the present invention includes:

[0031] 101. Dynamically configure the bill template, store the bill template in the template library and import it into the cache;

[0032] In this embodiment, the specific requirements and format of the face sheet, including fields, layout and style, are understood, and a face sheet template is designed according to the requirements. It may be necessary to support different variables and conditional formats, and dynamically configure the parameters of the template, such as font size, field position, etc., to adapt to different printing requirements. A record is created in the template library for each face sheet template, including information such as the template ID, description, configuration parameters, etc., and a suitable storage method (such as a database or file system) is selected to save the template file and related configurations. The template is version managed to track and restore different versions of templates, and the cache strategy is determined, such as the cache refresh cycle, cache size, etc. The template is loaded from the template library into the cache to improve the access speed, and a cache management mechanism is implemented, including update, invalidation and cleanup strategies to maintain the validity and accuracy of the cache.

[0033] 102. Receive the order request instruction sent by the mobile APP, and determine whether the order request instruction needs to be configured as a shipping label;

[0034] In this embodiment, an API interface or a message receiving endpoint is created to receive an order request instruction from a mobile APP. After receiving the request, the integrity and validity of the request data are verified, including the fields, format, and required parameters of the request. Key information such as order number, user information, print content, etc. are extracted from the request. The request data is converted into a format that the system can process based on data mapping or conversion logic, and a rule engine or conditional judgment logic is used to determine whether a configured delivery note is required.

[0035] 103. If yes, identify the template format required in the order request instruction, and call the target template corresponding to the template format from the cache;

[0036] In this embodiment, if a configured face sheet is required, the specified template format information is extracted from the face sheet request instruction. This is a field or parameter that contains a template ID, a format identifier or other relevant information. Based on the extracted information, the required template format is determined, and it is ensured that the cache system has been designed to store and retrieve the target template corresponding to the template format. The identified template format information is used to retrieve the corresponding target template from the cache, and the template retrieved from the cache is loaded into the processing system in preparation for further operations.

[0037] 104. Extract the order information in the order request instruction, fill the order information in the target template, and obtain the filled template;

[0038] In this embodiment, order information is extracted from the order request instruction, the target template previously obtained from the cache is loaded into the processing system, the extracted order information is mapped to the placeholder of the target template, the filling logic is applied, the order data is inserted into the template, the filled data is synthesized with the target template, and a complete filled template is generated. It is ensured that the filled template conforms to the expected format and layout, and necessary formatting processing is performed, such as alignment and font adjustment, to ensure the clarity and readability of the template. The generated filled template is checked to ensure that the order information is correctly and completely displayed in the template, and a preview function is provided for manual inspection and confirmation to ensure that the final template meets printing or display requirements.

[0039] 105. Generate a configuration printing instruction according to the filled template, and send the configuration printing instruction back to the mobile APP, so that the mobile APP sends the configuration printing instruction to the portable printer;

[0040] In this embodiment, a configuration printing instruction that meets the requirements of the portable printer is created based on the template content and the printing configuration. The configuration printing instruction includes the filled order information and detailed layout data. After the configuration printing instruction is returned to the mobile APP, the mobile APP sends the configuration printing instruction to the portable printer through the Bluetooth channel, so that the portable printer prints the order according to the configuration printing instruction.

[0041] In an embodiment of the present invention, by dynamically configuring the face bill template, the face bill template is stored in a template library and imported into a cache, and the update of the face bill template is pre-placed, which has high flexibility and is globally controllable. It can be updated to the entire network in a timely manner, shortening the processing cycle, and receiving a bill request instruction sent by a mobile APP. When the bill request instruction needs to configure the face bill, the template format required in the bill request instruction is identified, and the target template corresponding to the template format is called from the cache. The order information in the bill request instruction is extracted, and the order information is filled in the target template to obtain a filled template. A configuration printing instruction is generated according to the filled template, and a new printing instruction is directly generated at the data generation end according to the newly added face bill template, so as to quickly respond to new printing requests, improve printing efficiency, improve user experience, and improve user satisfaction.

[0042] See also Figure 2 The second embodiment of the method for implementing the configurable electronic bill printing in the embodiment of the present invention includes:

[0043] 201. Obtain configuration feedback information of the mobile APP;

[0044] In this embodiment, the user provides configuration information through the feedback mechanism within the APP. The APP provides a setting or feedback interface in which the user can modify the settings, enter feedback or submit questions. The user's settings and feedback are collected through forms, sliders, switches or text boxes within the application. The user's configuration feedback information is converted into an appropriate data format, such as JSON or XML, for transmission and storage. A network request (such as HTTP or HTTPS) is used to send data from the user device to the server. The server receives the configuration feedback information from the user device, parses the data format, and stores the configuration feedback information in a database for subsequent processing.

[0045] 202. Obtain a template list from the template library, and dynamically update the template elements according to the template list and configuration feedback information;

[0046] In this embodiment, a connection is made to a database or file system storing templates to obtain a list of available templates, and configuration feedback information is received and parsed, which includes data entered by the user, changes to print settings, requirements for adjustment of template content, etc. According to the requirements in the configuration feedback information, the missing template elements in the template list are dynamically updated, that is, specific elements in the template are modified, such as text, images, layouts, etc.

[0047] 203. Edit the template element to obtain the delivery bill template;

[0048] In this embodiment, the face sheet template is obtained by editing the template elements, for example, adjusting the layout position, adjusting the border, replacing the image, etc. The template settings, such as font size, color, style, etc., are adjusted according to the configuration feedback information to meet user needs or printing requirements, and the updated template is saved in the template library.

[0049] 204. Store the bill template in the template library and import it into the cache;

[0050] In this embodiment, the edited face sheet template is saved in a suitable file format to ensure that the file is complete and correct, the template file is uploaded to the template library, the template is classified into appropriate categories, and tags are added to facilitate quick retrieval and organization, the template's access permissions are configured to ensure that only authorized users can view or edit the template, the cache mechanism is used to improve the template loading speed, and the newly saved template is imported into the cache.

[0051] 205. Receive the order request instruction sent by the mobile APP, and parse the order request instruction using the message parsing rule to obtain request instruction parsing information, where the request instruction parsing information includes order information and printing parameter information;

[0052] In this embodiment, the mobile APP sends an order request instruction to the server through a network protocol (such as HTTP, HTTPS, etc.), converts the received request instruction into an operable data structure using message parsing rules, extracts order-related data from the message, such as order number, product details, quantity, recipient information, etc., and extracts printing-related settings from the message, such as border parameter values, layout position, etc.

[0053] 206. Check the printing parameter information and obtain a check result;

[0054] In this embodiment, each field is extracted from the parsed printing parameter information, the valid range and format of each printing parameter are determined, and it is checked whether the format of the printing parameters meets expectations, for example, whether the layout position is within the preset options, and whether the border parameter value is within the allowable range, for example, whether the width and height of the border are within the preset size range.

[0055] 207. Determine whether the bill request instruction needs to be configured as a bill based on the inspection result;

[0056] In this embodiment, the inspection results of the printing parameters in the previous step are checked to determine whether all the parameters meet the expected standards and ranges. If the inspection results show that the parameters are invalid or erroneous, it is necessary to configure the face sheet to ensure that the generated face sheet meets the requirements. If the parameters are valid and meet the standards, it is not necessary to configure the face sheet.

[0057] 208. If the bill printing request instruction does not require a configured face sheet, a local general printing instruction is generated according to the bill printing request instruction, and the local general printing instruction is returned and sent to the mobile APP, so that the mobile APP sends the local general printing instruction to the portable printer;

[0058] In this embodiment, after confirming that the previous inspection results indicate that no face sheet configuration is required, the information in the order request instruction (such as order data and print content) is embedded in the general printing instruction, and the generated local general printing instruction is formatted as a response into a data format suitable for sending to the mobile APP. The printing instruction is sent to the mobile APP through an appropriate interface to ensure that the data transmission is complete and correct. After receiving the local general printing instruction, the mobile APP parses and processes it, and transmits the processed instruction to the portable printer to trigger the actual printing operation.

[0059] In an embodiment of the present invention, the system can dynamically update the template according to the configuration feedback information of the mobile APP, which enables the template to flexibly adapt to different needs and environmental changes. By obtaining the template list from the template library and adjusting it, the system can ensure that the generated face bill template meets the actual needs. The template generation and management process improves efficiency through centralized storage and caching mechanisms. The face bill templates are stored in the template library and imported into the cache, which reduces the delay in template loading and enables the printing task to be started quickly. The system standardizes the parsing of the bill request instructions through message parsing rules and verifies the printing parameter information to ensure the accuracy of the printing instructions. The use of the inspection results further improves the reliability of request processing and reduces the possibility of errors. The system can decide whether the face bill needs to be configured based on the inspection results, thereby avoiding unnecessary resource consumption. For requests that do not require configuration, local general printing instructions are generated to simplify the processing flow and improve resource utilization efficiency.

[0060] See also Figure 3 The third embodiment of the method for implementing the configurable electronic bill printing in the embodiment of the present invention includes:

[0061] 301. If the billing request instruction requires a configured bill, identify the format requirement field in the billing request instruction;

[0062] In this embodiment, if it is confirmed that the previous inspection result indicates that the waybill configuration is required, the format requirement field is extracted from the waybill request instruction.

[0063] 302. Analyze the format requirement semantics of the format requirement field, and determine the template format according to the format requirement semantics;

[0064] In this embodiment, the extracted fields are analyzed to determine their specific requirements and formats. Specifically, the field describes the meaning of each field in detail, and the specific semantics of each field is analyzed. For example, "margin setting" refers to the distance between the document content and the edge of the paper. The semantics of each field is mapped to the actual template setting, and the specific parameters of the template are determined according to the semantics of the field. For example, the margin parameters of the template are adjusted according to the margin setting, the font style and size in the template are set according to the font style and size, and the color scheme used in the template is set according to the color. The appropriate template format is selected according to the analyzed field semantics.

[0065] 303. Matching is performed in the cache based on the template format to obtain a matching result;

[0066] In this embodiment, the template format information that needs to be matched is extracted from the request, a template matching the request format is searched in the cache, a matching algorithm is applied to compare the request format with the template format stored in the cache, and a check is made to see whether the request format is completely consistent with a template format in the cache. The degree of matching is determined based on certain predefined patterns or rules. For example, certain fields are optional or have a certain tolerance. If a template that fully or partially matches the request format is found, the matching template information is returned to obtain a matching result.

[0067] 304. Extracting a corresponding target template according to the matching result;

[0068] In this embodiment, the matching result includes a template identifier (such as a template ID) or specific template data (such as a template object). If the matching result provides a template ID, this ID can be used in the template library or cache to find the corresponding template, and the data of the target template can be extracted based on the search result, including the layout, style, content, etc. of the template. If the template data has been cached, the template is directly extracted from the cache to increase access speed.

[0069] 305. Extract the order information in the order request instruction;

[0070] In this embodiment, the data format of the order request instruction is determined, and the instruction content is parsed to identify the fields contained in the instruction, such as order ID, product information, quantity, customer information, etc., and extract the unique identifier of the order for subsequent data retrieval and processing. The product details in the order are extracted, and customer-related information such as name, contact information, delivery address, etc. is obtained. The extracted data is converted into a format suitable for subsequent processing as needed, such as converting a date string into a date object.

[0071] 306. Clean the order information to obtain cleaned information, and convert the cleaned information into structured data;

[0072] In this embodiment, missing necessary fields are identified and processed, null values ​​in fields are processed, default values, average values, or records are selected to be filled according to actual conditions, all data fields are ensured to follow a consistent format, data is converted to the correct type, such as converting price strings to floating point numbers and date strings to date objects, duplicate data is identified and removed, unnecessary characters or data are removed, such as useless characters or extra spaces in order notes, outliers are detected and processed, such as negative numbers or invalid characters in price fields, erroneous data is corrected according to business rules, such as correcting invalid postal codes, data models are designed according to business requirements, such as organizing order information into structured data such as order ID, product list, and customer information, the cleaned information is mapped to a structured data model, for example, "product name" and "product quantity" are mapped to fields in the "product list", and the cleaned data is converted into a structured format according to the defined data model.

[0073] 307. Fill the target template with structured data to obtain a filled template;

[0074] In this embodiment, the target template format to be used is confirmed, the fields in the template and their positions are understood, it is ensured that the fields in the structured data match the placeholders or fields in the template, necessary data fields such as customer name, order number, order date, etc. are extracted from the structured data source, and the placeholders in the template are replaced with the extracted data, for example, "customer name" is replaced with the actual customer name, and the data is inserted into the corresponding position in the template according to the field mapping, ensuring that the format of the filled data is consistent with the template requirements, and the filled template is saved in the specified format as needed, and the file is saved using the appropriate naming convention.

[0075] 308. Generate configuration printing instructions based on the filled template;

[0080] In this embodiment, it is determined whether the verification result shows that there is no mismatch or omission.

[0081] 311. If yes, encapsulate the configuration printing instruction according to a preset data format to obtain printing instruction information;

[0082] In this embodiment, if there is no mismatch or omission in the verification result, the preset data format requirements are found, all relevant data are extracted from the configuration printing instructions that have passed the verification, the extracted data is organized and formatted according to the preset data format, and the corresponding tools or libraries are used to generate a data structure that meets the format requirements, and the formatted data is written into a file to ensure that the file meets the preset data format, and the printing instruction information is obtained.

[0083] 312. Send the printing instruction information to the mobile APP, so that the mobile APP sends the printing instruction information to the portable printer;

[0084] In this embodiment, an API or SDK is used to send data to a mobile APP. After receiving the printing instruction information, the mobile APP performs parsing and verification.
