[0055] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0056] In the current information environment, the printing function of data information plays a vital role in various business scenarios, especially in the fields of banking, finance, and corporate office. Although traditional data information printing methods, such as printing technology based on the Microsoft Foundation Class Library (MFC), performed well in the past Windows operating system environment, with the continuous advancement of information technology and the in-depth implementation of the Xinchuang (information technology application innovation) strategy, these traditional technologies are facing more and more challenges.

[0057] First, the incompatibility of MFC technology in the Info-Chuang operating system environment is becoming increasingly prominent. Due to differences in system architecture and API interfaces, the data information printing function developed using MFC technology cannot work properly on the Info-Chuang operating system, which has brought great obstacles to the migration and upgrade of business systems.

[0058] Secondly, the development and maintenance costs of MFC technology are high. As a traditional code encoding method, the development and maintenance process of MFC technology is relatively cumbersome and complex, requiring a lot of manpower and time investment. Especially when developing printing functions for different types of vouchers and reports, MFC technology often requires a lot of customized development, which not only increases the development cost, but also increases the difficulty of later maintenance.

[0059] In addition, the existing printing controls on the market have obvious shortcomings in terms of dynamic template support and adjustment. These controls are often unable to flexibly respond to diverse printing needs, especially in scenarios that require processing large amounts of data information and complex typesetting requirements. This further weakens the flexibility and applicability of data information printing and affects the user experience.

[0060] Therefore, in order to meet these challenges, the industry urgently needs a new method for printing data information.

[0061] Based on this, the embodiments of the present application provide a method, device, equipment, medium and program product for printing data information, which can solve the problems of incompatibility of traditional MFC technology in the trusted operating system environment, complex development and maintenance, and insufficient support for dynamic templates of printing controls. It is compatible with different operating system environments, supports dynamic template adjustment and typesetting, reduces development and maintenance costs, and improves user experience.

[0062] The following is a detailed description of the method for printing data information provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0063] Figure 1 is a flow chart of a method for printing data information provided by an embodiment of the present application, such as Figure 1 As shown, the method may include steps S110 to S150.

[0064] S110, in response to the data printing request, acquiring data information and template identification information in the data printing request.

[0065] The data printing request is a printing request for data information sent by the application system.

[0066] Specifically, in response to a data printing request, the data information to be printed and the template identification information contained in the request are extracted.

[0067] S120, obtaining a web page template corresponding to the template identification information in a preset web page template library, wherein the web page template is written based on a preset hypertext markup language.

[0068] Among them, Hyper Text Markup Language (HTML) is a descriptive markup language that can define the structure and content of a web page template.

[0069] Specifically, in a web page template set written in the predefined hypertext markup language HTML, the web page template corresponding to the template identification information can be retrieved and obtained according to the provided template identification information. The hypertext markup language HTML has significant advantages such as rich functions, high flexibility, easy expansion and maintenance, so the web page template written in the predefined hypertext markup language HTML can easily realize the dynamic filling and layout adjustment of the voucher content, and support a variety of font styles and layout methods to meet diverse printing needs.

[0070] S130, filling the data information into the preset position of the webpage template to obtain the target webpage template.

[0071] Specifically, by accurately filling the data information to be printed into the specified position in the pre-designed web page template, a target web page template containing the data information can be generated.

[0072] S140, typeset the content in the target web page template according to preset parameters to generate a portable document format file.

[0073] The preset parameters are parameters related to typesetting, such as preset conversion area, resolution size, scaling ratio, etc. The preset parameters can be set as needed, and the present application embodiment does not limit this.

[0074] Portable Document Format (PDF) files can contain a variety of elements such as text, images, links, audio and video, and are compatible across platforms, devices and applications. No matter which operating system or software the user is using, they can view and print PDF files without losing formatting or content.

[0075] Specifically, according to pre-set layout parameters (such as preset conversion area, resolution size, zoom ratio and other parameters), the target web page template that has been filled with content is converted and saved as a portable document format (such as PDF) file that is easy to share, view and print.

[0076] It should be noted that since the filled-in target web page template relies on the rendering and display of the browser, resulting in different display effects on different monitors, you can specify layout parameters such as conversion area, fixed resolution, zoom ratio, etc., and convert the target web page template into a portable document format file to ensure output consistency.

[0077] S150, using the print service of the target operating system to print the portable document format file.

[0078] Specifically, the built-in printing service function of the target operating system is called to send the portable document format,file to the connected printer for physical print output.

[0079] According to the printing method of data information provided by the embodiment of the present application, by responding immediately to the data printing request, accurately according to the template identification information in the request, select a suitable web page template from a rich web page template library, accurately fill the data information into the preset position of the web page template, and generate a target web page template, wherein the web page template generated by HyperText Markup Language (HTML) has more functions, higher flexibility, and is easier to expand and maintain. Then, according to the preset typesetting parameters, such as the specified conversion area, fixed resolution, scaling and other parameters, the content in the web page template is typeset, so that the consistency of the portable document format files generated by different browsers can be guaranteed. Finally, the printing service provided by the target operating system (such as the Xinchuang operating system) is used to realize the printing of portable document format files, without relying on a specific operating system environment, ensuring the wide compatibility and high availability of the printing function, and being able to solve the problems of incompatibility of traditional MFC technology in the Xinchuang operating system environment, complex development and maintenance, and insufficient support for dynamic templates of printing controls. It can be compatible with different operating system environments, support dynamic template adjustment and typesetting, reduce development and maintenance costs, and improve user experience.

[0080] Figure 2 This is another flow chart of the method for printing data information provided in the embodiment of the present application.

[0081] In some embodiments, Figure 2 As shown, the data information includes text information, and the text information includes text content and text style. Step S130 fills the data information into the preset position of the webpage template to obtain the target webpage template, which may include step S131.

[0082] S131, filling the text content into the preset position of the webpage template according to the text style to obtain the target webpage template.

[0083] The data information may include text information.

[0084] Text information may include text content and text style.

[0085] Text style refers to the appearance of text, which can include font type (such as Songti, Heiti, Kaiti, etc.), font size (such as 12, 14, 16, etc.), font color, font bold, font italic, underline, strikethrough and other attributes. Text style is used to define the visual appearance of text in a web page or document to meet specific needs.

[0086] Specifically, when the data information input by the user includes text information and the text information includes text content and text style, for example, the text content is accurately placed at a predetermined position of the web page template according to the specific style of the text (such as font, size, color, etc.), thereby generating the desired target web page template.

[0087] In the embodiment of the present application, when the data information input by the user includes text information and the text information includes text content and text style, the text information containing user-customized text content and text style (such as font type, size, color, bold, italic, underline, etc.) can be fully utilized, and a highly customized target web page template can be generated by accurately filling this information into the preset position of the web page template, thereby greatly improving the efficiency and accuracy of template production, being able to accurately meet specific printing needs, and improving user experience.

[0088] Figure 3 This is another flow chart of the method for printing data information provided in the embodiment of the present application.

[0089] In some embodiments, Figure 3 As shown, the data information includes text information, and the text information includes text content. Step S130 fills the data information into the preset position of the webpage template to obtain the target webpage template, which may include step S132.

[0090] S132, filling the text content into the preset position of the webpage template according to the first preset text style to obtain the target webpage template.

[0091] The first preset text style is a predefined text appearance setting (such as font, size, color, etc.).

[0092] Specifically, when the data information input by the user includes text information (only text content), the text content can be filled into the designated position of the webpage template according to the default first text style (such as default font, default size, default color, etc.), thereby generating a target webpage template that meets the unified preset format requirements. For example, the first preset text style is Songti size 4 black, then when the text information input by the user does not include a text style, the default first preset text style is used to fill the text content in the text information into the webpage template.

[0093] When the user only provides text information of text content, the embodiment of the present application can automatically and accurately fill these contents into the specified position of the web page template according to the pre-set first text style, quickly generate a target web page template that meets the unified preset format requirements, and greatly improve the efficiency of document production.

[0094] Figure 4 This is another flow chart of the method for printing data information provided in the embodiment of the present application.

[0095] In some embodiments, Figure 4 As shown, step S132 fills the text content into the preset position of the web page template according to the first preset text style to obtain the target web page template, which may include steps S1321 and S1322.

[0096] S1321, obtaining information of a preset text content information library corresponding to the first preset text style.

[0097] The preset text content information library corresponds to the preset text style (such as font) one by one. For example, Songti corresponds to one preset text content information library, and Heiti corresponds to another preset text content information library, and each font has its own preset text content information library.

[0098] Specifically, when the text information input by the user only includes text content, the default first preset text style can be used to fill the text content into the webpage template. It is necessary to first find a preset text content information library corresponding to the first preset text style, which includes all preset text contents that conform to the first preset text style.

[0099] S1322: When the preset text content information library does not include the text content, fill the text content into the preset position of the web page template according to the second preset text style to obtain the target web page template.

[0100] Specifically, if the preset text content information library corresponding to the first preset text style does not have preset text content that matches the text content specified by the user, the second preset text style can be used instead, and the text content specified by the user can be filled into the preset position of the webpage template, thereby generating a target webpage template. For example, if the preset text content information library corresponding to Songti does not include the text content specified by the user, the subsequent fonts can be used until the preset text content information library corresponding to the subsequent fonts includes the text content specified by the user. This solves the problem that rare characters cannot be printed.

[0101] In the embodiment of the present application, when the user only provides text information of text content, by presetting a text content information library that corresponds one to one with text styles, the content of the first preset text style is preferentially tried to match, and if there is no match, it is automatically converted to the second preset text style, thereby ensuring that the text content specified by the user (including possible rare characters) can be accurately filled into the preset position of the web page template, thereby effectively generating a target web page template, improving the compatibility and flexibility of printing or displaying data information, and being able to flexibly respond to printing needs of different text content.

[0102] In some embodiments, the data information includes at least one of text information, QR code information, electronic signature information, and electronic seal information.

[0103] The data information of the embodiments of the present application may include at least one of text information, QR code information, electronic signature information and electronic seal information, which greatly enriches the expression form and application scenarios of data information, improves the flexibility and integrity of data information printing, and meets diversified and complex printing needs.

[0104] Figure 5 Another flowchart of a method for printing data information provided in an embodiment of the present application.

[0105] In some embodiments, Figure 5 As shown, before the content in the target webpage template is typeset according to preset parameters and a portable document format file is generated in step S140, the data information printing method further includes steps S161 to S163.

[0106] S161, on the target page, display information of the target web page template.

[0107] Specifically, the specific content of the completed target web page template is displayed on the target page, and the information of the target web page template before printing can be intuitively displayed, which is convenient for users to preview and confirm.

[0108] S162: When receiving a first input in the target page, obtain input information in the first input.

[0109] Among them, after the user previews the information of the target webpage template on the target page, if the template information needs to be modified, the user can enter the corresponding modification content by clicking the target control in the target page, and the modification content can be called the first input.

[0110] Specifically, when the user performs an input operation to modify the content on the target page, the information included in the input can be obtained.

[0111] S163, adjusting the target webpage template according to the input information to obtain an adjusted target webpage template.

[0112] Specifically, based on the modification content input by the user in the target page, the target webpage template can be modified accordingly, thereby generating an adjusted target webpage template that better meets the user's needs.

[0113] Step S140 typesets the content in the target webpage template according to preset parameters to generate a portable document format file, which may include step S141.

[0114] S141, typeset the content in the adjusted target web page template according to preset parameters to generate a portable document format file.

[0115] Specifically, according to the pre-set layout parameters, the adjusted target webpage template content can be formatted and laid out, and finally saved as a portable document format (such as PDF) file.

[0116] The embodiment of the present application can intuitively display the information of the target web page template before printing by displaying the information of the target web page template on the target page, which is convenient for users to preview and confirm, improves the accuracy of printing, and can adjust the template by entering modification content when the user needs. Finally, the adjusted template is typeset according to preset parameters and a portable document format file is generated, thereby improving printing efficiency and accuracy and better meeting the needs of users.

[0117] Figure 6 It is an overall architecture diagram of the data printing method provided in the embodiment of the present application.

[0118] In one example, if Figure 6 As shown, the printing of data information can be completed through the application system, data printing middleware, ICT terminal and printer. The data printing middleware may include a data printing business processing module and an HTML to PDF tool. The application system is used to issue a data printing request. The data printing business processing module in the data printing middleware is used to respond to the data printing request, extract the data information and template identification information in the data printing request, and fill the data information into the web page template corresponding to the template identification information. After generating the target web page template, call the HTML to PDF tool to convert the target web page template into a portable document format file, and then call the printing service of the ICT terminal to send the portable document format file to the printer to drive the printer to print the document.

[0119] Among them, the trusted computing terminal is the domestically produced operating system terminal of the trusted computing system, such as: counter customer terminal, STM, STAM, etc.

[0120] It should be noted that middleware is a type of software between the application system and the system software. It uses the basic services provided by the system software to connect the various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing. Middleware technology can shield the heterogeneity between hardware platforms and the differences between operating systems and network protocols, so that the application system can run smoothly and efficiently on different platforms. In the structure of the financial terminal application system, the middleware layer is located between the operating system layer and the application software layer.

[0121] It should also be noted that data printing middleware, as a peripheral middleware, can be widely transplanted to the peripheral terminals of domestic systems, and has wide adaptability and practicality.

[0122] The embodiment of the present application, through the collaborative work of the application system, data printing middleware, the trusted terminal and the printer, utilizes the business processing module and HTML to PDF tool in the data printing middleware, can efficiently fill the data information into the corresponding template and convert it into a PDF file, and then realize printing through the printing service of the trusted terminal. It can solve the problems of incompatibility of traditional MFC technology in the trusted operating system environment, complex development and maintenance, and insufficient support for dynamic templates of printing controls. It is compatible with different operating system environments, supports dynamic template adjustment and typesetting, reduces development and maintenance costs, and improves user experience.

[0123] Figure 7 It is an overall architecture diagram of the data printing method provided in the embodiment of the present application.

[0124] In another example, Figure 7 As shown, the data printing method may include steps S01 to S11.

[0125] S01, in response to a data printing request, acquiring data information and template identification information in the data printing request.

[0126] For example, the data information in the data printing request is voucher information. The user can check the accuracy of the account transaction record and resource balance by consulting the printed voucher to ensure that the account information is correct.

[0127] It should be noted that most of the controls in the related technologies do not support dynamic voucher templates or the voucher templates are difficult to adjust. In addition, the printing technology based on the Microsoft Foundation Class Library (MFC) uses code for template encoding, which is very inflexible and requires complex encoding for each voucher.

[0128] S02, obtaining a web page template corresponding to the template identification information in a preset web page template library, wherein the web page template is written based on a preset hypertext markup language HTML.

[0129] Web page templates are implemented using HTML, which is very flexible and can respond to business printing needs quickly and instantly compared to existing templates in other programming languages ​​(such as C++ templates).

[0130] S03, when the data information includes text information and the text information includes text content and text style, fill the text content into a preset position of the webpage template according to the text style to obtain a target webpage template.

[0131] When the data information input by the user includes text information and the text information includes text content and text style, the text information containing user-customized text content and text style (such as font type, size, color, bold, italic, underline, etc.) can be fully utilized. By accurately filling this information into the preset position of the web page template, a highly customized target web page template is generated, which greatly improves the efficiency and accuracy of template production, can accurately meet specific printing needs, and improves user experience.

[0132] For example, when the previous font cannot print a certain Chinese character, the subsequent font is used to print it instead to meet the printing requirements of rare characters.

[0133] S04: When the data information includes text information and the text information only includes text content, obtain information of a preset text content information library corresponding to the first preset text style.

[0134] S05: When the preset text content information library does not include the text content, fill the text content into the preset position of the webpage template according to the second preset text style to obtain the target webpage template.

[0135] When the user only provides text information of text content, through the preset text content information library that corresponds one to one with the text style, priority is given to trying to match the content of the first preset text style. If there is no match, it is automatically converted to the second preset text style, ensuring that the text content specified by the user (including possible uncommon characters) can be accurately filled in the preset position of the web page template, thereby effectively generating the target web page template, improving the compatibility and flexibility of printing or displaying data information, and being able to flexibly respond to the printing needs of different text content, which can solve the problem that existing domestically produced terminals do not support uncommon characters.

[0136] It should be noted that the fpdfsdk open source solution is used in some related technologies. The text content of the voucher print is converted into a pdf file using the fpdfsdk api, and then the cups printing component instruction of the trusted operating system is called to print the pdf, thereby realizing voucher printing. However, during the operation of the first version of the trusted voucher printing function mentioned above, a series of problems occurred: 1) The voucher printing template is not flexible. fpdf is a python sdk, and complex encoding using the python language is required for each voucher. 2) fpdfsdk does not support the implementation of font attributes such as bold and italics. Since only one font can be set (the existing uncommon character standard GB18030-2022 requires three fonts to cover all Chinese character glyphs), it is also impossible to achieve complete uncommon character printing.

[0137] S06, filling the QR code information, electronic signature information and electronic seal information in the data information into the preset position in the web page template.

[0138] For example, the data printing business processing module escapes HTML according to the text elements sent by the application system and draws it in the HTML web page template, supports italics, bold and underline, and supports the configuration of multiple fonts; escapes HTML according to the voucher QR code elements sent by the application system, converts the QR code text into a QR code image and draws it in the HTML web page template; escapes HTML according to the voucher electronic signature elements sent by the application system, draws the electronic signature image in the HTML web page template; escapes HTML according to the voucher electronic seal elements sent by the application system, and draws the electronic seal image in the HTML web page template.

[0139] S07, on the target page, displaying information of the target web page template.

[0140] S08: When receiving a first input in the target page, obtain input information in the first input.

[0141] S09, adjusting the target webpage template according to the input information to obtain an adjusted target webpage template.

[0142] S10, typeset the content in the adjusted target webpage template according to preset parameters to generate a portable document format file. Convert to PDF before printing, the PDF typesetting is fixed and does not depend on the printer's typesetting. Compared with the traditional method of sending instructions to the printer, the PDF typesetting and printing method has obvious advantages.

[0143] For example, the data printing service processing module calls the HTML to PDF tool to convert the HTML template with drawn content into PDF.

[0144] S11, using the print service of the target operating system to print the portable document format file.

[0145] The embodiment of the present application supports dynamic customization and adjustment of printed content, including text styles, QR codes, electronic signatures, and electronic seals, by flexibly using HTML web page templates. At the same time, it solves the problem of printing uncommon characters, improves printing efficiency and accuracy, and ensures the consistency and independence of printing layout by converting to PDF format files in advance, thereby optimizing the printing effect.

[0146] In one example, a web page template is developed using HTML, and JavaScript scripts are used to add interactivity and dynamic functions to the web page template, so that the web page template can respond to user operations and events (such as data printing requests), and implement complex logic processing and data operations, and can fill data information into the web page template to generate a target web page template. Due to the flexibility of HTML and JavaScript, the web page template can flexibly adjust the text size, text style, image size and graphic style of specific credential fields. This solves the problem that the original Python / C++ template can only adjust the entire text or graphic.

[0147] Based on the same inventive concept, the embodiment of the present application also provides a data information printing device, such as Figure 8 As shown, the device 800 may include an acquisition module 810 , a filling module 820 , a typesetting module 830 and a printing module 840 .

[0148] The acquisition module 810 is used to acquire data information and template identification information in the data printing request in response to the data printing request;

[0149] The acquisition module 810 is further used to acquire a web page template corresponding to the template identification information in a preset web page template library, wherein the web page template is written based on a preset hypertext markup language;

[0150] Filling module 820, used to fill data information into the preset position of the webpage template to obtain the target webpage template;

[0151] The layout module 830 is used to layout the content in the target web page template according to preset parameters and generate a portable document format file;

[0152] The printing module 840 is used to print a portable document format file using the printing service of the target operating system.

[0153] According to the data information printing device provided by the embodiment of the present application, by responding immediately to the data printing request, accurately according to the template identification information in the request, select a suitable web page template from a rich web page template library, accurately fill the data information into the preset position of the web page template, and generate a target web page template, wherein the web page template generated by HyperText Markup Language (HTML) has more functions, higher flexibility, and is easier to expand and maintain. Then, according to the preset typesetting parameters, such as the specified conversion area, fixed resolution, scaling and other parameters, the content in the web page template is typeset, so that the consistency of the portable document format files generated by different browsers can be guaranteed. Finally, the printing service provided by the target operating system (such as the Xinchuang operating system) is used to realize the printing of portable document format files, without relying on a specific operating system environment, ensuring the wide compatibility and high availability of the printing function, and being able to solve the problems of incompatibility of traditional MFC technology in the Xinchuang operating system environment, complex development and maintenance, and insufficient support for dynamic templates of printing controls. It can be compatible with different operating system environments, support dynamic template adjustment and typesetting, reduce development and maintenance costs, and improve user experience.
