[0054] Exemplary Methods

[0055] Figure 1 FIG. 1 is a flow chart of a message queue-based invoice printing method provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 1 As shown, the message queue-based invoice printing method 100 includes the following steps:

[0056] Step 101, establishing a connection between the user's printing terminal and the digital electricity invoice cloud platform, obtaining the generated invoice information of the printing terminal, and generating multiple printing requests according to the generated invoice information, wherein the printing request includes one or more invoices;

[0057] Step 102, receiving the print request sent by the print terminal through the print server, and forwarding and storing multiple print requests into corresponding different request queues according to the printer name in the print request;

[0058] Step 103: Check the status of all connected printers through the consumption thread pre-built on the print server. When the printer is idle and the corresponding request queue is not empty, select the first print request in the corresponding request queue to dequeue, and call the invoice query interface provided by the digital electricity invoice cloud platform to obtain the complete invoice information of the print request, and generate the invoice printing information;

[0059] Step 104, push the printing information to the printer to print the invoice.

[0060] Specifically, the present invention provides a high-performance invoice printing method based on a message queue, which can efficiently process single or batch invoice printing requests pushed by motor vehicle companies. Each print request includes the corresponding invoice number interval and printer name, which are forwarded and stored in the corresponding request queue. After the request is dequeued, the print server can query the digital invoice cloud platform once or in batches according to the type of invoice number interval it contains, return the complete motor vehicle invoice information, generate the corresponding printing information, and finally push it to the designated printer for printing. This method effectively improves the utilization rate of the printer, reduces the waiting time for printing requests in peak periods, and improves the efficiency of invoice printing.

[0061] Specifically, refer to Figure 2 As shown, the present invention includes a printing terminal, a printing server, a digital invoice cloud platform, and a printer.

[0062] The printing terminal can be a web business management system or a mobile app. The customer selects a single or multiple invoices through the printing terminal and associates them with the printer information to generate a print request, which is then sent to the queue of the print server; it supports viewing and counting the invoice information generated in the digital invoice cloud platform.

[0063] The print server includes a request production module, a request consumption module, and a request queue. The request production module can receive print requests sent by the print terminal, forward and store the print requests in different request queues according to the printer name; the request consumption module checks the status of all connected printers, selects the first print request in the request queue to dequeue when the printer is idle, and then calls the invoice query interface provided by the digital invoice cloud platform to obtain the complete invoice information, generates invoice printing information, and finally pushes it to the printer for invoice printing. The request queue is used to store the print requests sent by the print terminal, and the number of printer queues is consistent with the actual number of printers.

[0064] The Digital Invoice Cloud Platform is used to store all invoice information that has been generated by the enterprise, provide invoice list data for the printing terminal, and provide an invoice information query interface for the printing server to return complete invoice information.

[0065] The printer can be a local printer or a network printer, and can be connected to a print server to provide invoice printing functions. Multiple printers can be connected to the same print server at the same time, and each printer corresponds to a print queue.

[0066] The present invention mainly includes two processes: a print request production module and a request consumption module. Figure 3 The specific operation process is as follows:

[0067] The print request production module process is as follows:

[0068] 1) After the printing terminal establishes a connection with the digital invoice cloud platform, it sends identity authentication information to the digital invoice cloud platform. After the authentication is passed, the printing terminal can view the information of the generated invoice according to its own permissions;

[0069] 2) Customers can select a single invoice and associate it with a printer to generate a print request;

[0070] 3) You can also select multiple invoices and associate them with a printer information to generate a print request;

[0071] 4) The printing terminal connects to the print server and sends the print request to the print server.

[0072] 5) The print server forwards the print request to different print queues according to the printer name in the print request, waiting for printing.

[0073] The print request consumption module process is as follows:

[0074] 1) The print server can connect to multiple printers at the same time. One printer corresponds to one print request queue, and each request queue is assigned a consumer thread for business processing;

[0075] 2) The consumer thread first determines whether the corresponding printer is idle. If the printer is idle, it takes the first request in the print request queue. If the print queue is empty at this time, the processing thread sleeps for a period of time and then repeats step 2);

[0076] 3) When the consumer thread receives a single invoice printing request, it can obtain complete invoice information by requesting the digital invoice cloud platform once;

[0077] 4) When the consumer thread receives a batch invoice printing request, it can request the digital invoice cloud platform in batches and multiple times to obtain complete invoice information;

[0078] 5) Generate invoice printing information based on invoice information and send it to the corresponding printer for printing;

[0079] 6) Record the invoice printing log and feed back the invoice printing result information to the Digital Invoice Cloud Platform;

[0080] 7) Determine whether the system is exited. If the system continues to execute, repeat steps 2) to 6) to process the invoice printing requests of the printing terminal concurrently.

[0081] The present invention is designed to design a high-performance invoice printing method based on a message queue for a large number of invoices that have been generated and are waiting to be printed. In this method, the customer queries the invoice list and the connected printer list in the digital invoice cloud platform through various forms of printing terminals such as web pages or mobile phone apps, and then selects invoices individually or in batches and pushes them to the invoice request queue of the print server. The print server determines the status of the printer and the request queue, selects an invoice printing request from the print request queue each time, and then queries the complete motor vehicle invoice information from the digital invoice cloud platform according to the print request. After the invoice printing information is generated, it is finally pushed to the corresponding printer for printing. The invoice printing method involved in the present invention realizes the printing of multiple invoices corresponding to multiple printers respectively, improves the utilization rate of the motor vehicle enterprise's printers, and reduces the number of manual operations and the waiting time for customers to receive invoices.

[0082] The key technical points of the present invention are:

[0083] 1. Use message queues to store and process print requests sent by print terminals, decouple print terminals and print servers, and process requests asynchronously, thereby alleviating system pressure during peak hours and effectively improving system stability and invoice printing efficiency.

[0084] The print server uses a network interface to communicate and can flexibly access the enterprise's business digital invoice cloud platform. Large-volume invoices are divided into batches corresponding to multiple printers, and can be seamlessly connected to the company's various existing printing devices, improving the reusability of the printing equipment and reducing the complexity of equipment maintenance.

[0085] Therefore, the invoice printing system provided by the present invention realizes efficient printing by adopting the print request production module and consumption module of the message queue on the basis of separating the invoice generation and printing functions. It is no longer limited to the mode of generating and printing one invoice at a time of the existing printing system, simplifies the invoice printing process of the enterprise, shortens the waiting time for customers to receive invoices, and improves the work efficiency of the enterprise.
