Description

Technical Field

[0001] The present invention relates to the technical field of silent printing, in particular to a method and system for realizing batch silent printing based on HTML. Background Art

[0002] With the development of information technology, the demand for batch printing by governments or enterprises is increasing. For general printing needs, printing is usually based on web pages. However, for printing with higher requirements or batch printing, web pages are often unable to achieve this. As for the third-party client printing controls on the market, the cost is often high or the printing effect is not ideal.

[0003] At the same time, government or corporate users hope to use a fixed printer every time they print, and no dialog box will pop up for settings, that is, silent printing. Specifically, when clicking print, no option window or printer setting window will pop up, and printing will be performed directly.

[0004] HTML, Hypertext Markup Language, is an application under Standard Generalized Markup Language. "Hypertext" means that a web page can contain pictures, links, and even non-text elements such as music and programs. The structure of Hypertext Markup Language includes a "header" part (English: Head) and a "body" part (English: Body), where the "header" part provides information about the web page and the "body" part provides the specific content of the web page.

[0005] Therefore, how to implement silent batch printing on the web based on HTML is a technical problem that needs to be solved urgently. Summary of the invention

[0006] The technical task of the present invention is to provide a method and system for implementing batch silent printing based on HTML, so as to solve the problem of how to implement batch silent printing on the web side based on HTML.

[0007] The technical task of the present invention is achieved in the following way: a method for implementing batch silent printing based on HTML, which extracts HTML data and maps it to a corresponding word template, and outputs the reversed word file to a local printer to implement silent printing during printing; the details are as follows:

[0008] Configure HTML template: Configure HTML according to the template to be printed to provide business data entry;

[0009] Configure the word template to be printed;

[0010] Configure the mapping between HTML and print word templates: map business items one by one according to the relationship between HTML and print word templates;

[0011] Replace the HTML form business data into the print word template;

[0012] When printing, the print job is sent directly to the local printer for silent printing.

[0013] As a preferred option, the word template to be printed is configured as follows:

[0014] Map the HTML business to the print word template;

[0015] When the HTML form business data is filled in and saved, the HTML form business data is replaced with the print word template;

[0016] When the form business data template changes, just modify the corresponding template.

[0017] As a preferred method, replace the HTML form business data with the printed word template as follows:

[0018] Enter the HTML form business data, and replace the form business data with the print word template according to the bookmark configured in the print word template when saving;

[0019] When printing, the generated word microservice is called to store the generated word file of the substitute form business data to the file server for printing and downloading.

[0020] Preferably, the print job is sent directly to the local printer for silent printing as follows:

[0021] Use nginx proxy to proxy the generated word files, and select the files to be printed in batches through IE browser;

[0022] When the generated word file is requested to be printed through nginx proxy, the server returns the file stream;

[0023] The IE browser starts the local office word application, and the office word application calls the print function to send the file stream to be printed to the printer to complete silent printing.

[0024] A system for implementing batch silent printing based on HTML, the system comprising:

[0025] HTML designer, used to draw the print word template into HTML and provide input of print business data;

[0028] The file server microservice is used to implement the maintenance interface of the HTML template and the conversion function of the HTML form data; it is also used to convert the form data into the printing word template data and store the printing word template data in the file service, and implement the maintenance interface of the printing word template and the mapping interface between the printing word template domain and the HTML domain;

[0029] The FastDFS architecture is used for clients to request Tracker servers to upload and download files. The files are then uploaded and downloaded by the Storage server through Tracker server scheduling.

[0030] As a preferred method, when Nginx calls to generate the word microservice, it finds the corresponding application service through the Nginx proxy and transmits the data to the corresponding word microservice;

[0031] When IE browser accesses the word file, the Nginx proxy has generated the word file and returns the file information on the file server to the IE browser according to the access path. IE can then directly obtain the file to be printed.

[0032] As a preferred embodiment, the ActiveX of the IE browser calls the local office word application interface technology to realize the transmission association between the local word application and the word file on the file server, and uses the officeword control of the ActiveX of the IE browser to realize the transmission of the word file on the file server to the local office word application; the details are as follows:

[0033] (1) By calling the print function of the Office Word control of ActiveX, the Word file stream on the file server is transferred to the local Office Word application;

[0034] (2) The local office word calls the printer again;

[0035] (3) Send the word file on the file server to the printer;

[0036] (4) The printer is awakened and silently prints the file stream on the file server.

[0037] Preferably, the FastDFS architecture has the following roles:

[0038] ① Tracker Server: used for scheduling and balancing; specifically:

[0039] Manage all storage servers and groups. After startup, each storage will connect to Tracker, inform the information of its group, and maintain periodic heartbeats. When uploading files, Trackerserver will find Storageserver according to the set strategy to provide file upload services.

[0040] ② Storage Server: Provides capacity and backup services; specifically:

[0041] The unit is group. There are multiple storage servers in each group, and the data is backed up by each other. Storage server does not implement its own file system but uses the file system of the operating system to manage files.

[0042] ③. Client: The server for uploading and downloading data, that is, the server where our own project is deployed.

[0043] Preferably, the working process of the system is as follows:

[0044] (1) Use HTML designer to draw the document template into HTML, and IE browser renders the drawn HTML to realize the document printing template input interface;

[0045] (ii) After completing the form data, submit it to the file server. The microservice that generates the word will process the data and replace the form data with the print word template using the bookmark, thereby writing the data back to the print word template;

[0046] (3) When printing, generate a word file and save it to the file server.

[0047] A computer-readable storage medium stores a computer program, and the computer program can be executed by a processor to implement the above-mentioned method for implementing batch silent printing based on HTML.

[0048] The method and system for implementing batch silent printing based on HTML of the present invention have the following advantages:

[0049] (i) The present invention configures form templates and word printing templates through an interface, maps the business relationship between forms and printing templates, directly selects the print form browser to start local office word when printing, and returns the print task to the printer. Compared with the traditional batch printing method, only office word needs to be installed on the client, while many third-party printing methods require the installation of third-party plug-ins;

[0050] (ii) The present invention is based on HTML and has good compatibility with previous business systems, which not only saves development costs but also has good expansibility and applicability; it also provides a visual configuration interface, which can be customized by printing templates;

[0051] (III) The form template configuration of the present invention is flexible and can be configured in different versions according to different forms;

[0052] (iv) The printing word template of the present invention can configure different templates according to versions, map the business relationship of the form to the printing template, and multiple templates can be configured with multiple business relationships;

[0053] (V) When printing, the present invention directly selects the print form browser to start the local office word, and returns the print task to the printer. The printer does not need to preview, which saves a lot of operation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] The FastDFS architecture is used for clients to request Tracker servers to upload and download files. The files are then uploaded and downloaded by the Storage server through Tracker server scheduling. The FastDFS architecture has the following roles:

[0093] ① Tracker Server: used for scheduling and balancing; specifically:

[0094] Manage all storage servers and groups. After startup, each storage will connect to Tracker, inform the information of its group, and maintain periodic heartbeats. When uploading files, Trackerserver will find Storageserver according to the set strategy to provide file upload services.

[0095] ② Storage Server: Provides capacity and backup services; specifically:

[0096] The unit is group. There are multiple storage servers in each group, and the data is backed up by each other. Storage server does not implement its own file system but uses the file system of the operating system to manage files.

[0097] ③. Client: The server for uploading and downloading data, that is, the server where our own project is deployed.
