Detailed ways

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar promotions without violating the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

FIG. 1 is a structural block diagram of a high-performance invoice printing system provided by the present application. The system provided by the present invention will be described in detail below with reference to FIG. 1 .

As can be seen from Figure 1, the high-performance invoice printing system includes: a printing terminal, a printing server, a high-speed printer, and an invoice platform.

The print terminal is used to send a print request and display the list of invoices and printers that have been generated in the invoice platform. The printing terminal selects a single or multiple invoices to generate a print request, sends the print request to the print server, and displays the print progress returned by the print server. The printing terminal can be a web service 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, and then send it to the queue of the print server; it supports viewing and statistics of the invoice information generated in the invoice platform.

The print server uses the RabbitMQ message queue to receive and store invoice printing requests, query the invoice platform and download invoice details according to the invoice printing requests;

RabbitMQ is an open source message broker and queue server. It is used to share data between completely different applications through common protocols. It has strong concurrency capability, extremely good performance and low latency. Therefore, this application uses RabbitMQ to improve the printing of the system. performance.

Print server, including: request production module, request consumption module, RabbitMQ request queue.

The request production module receives the print request sent by the print terminal; forwards and stores the print request in different request queues according to the printer name.

Request the consumption module, check the status of all connected printers, select the first print request in the request queue to dequeue when the printer is idle, call the invoice query interface provided by the invoice platform to obtain the complete invoice information, generate the invoice printing information, and print the invoice printing information. Push to the printer for invoice printing;

The RabbitMQ request queue is used to store print requests sent by the print terminal. The number of printer queues is consistent with the actual number of printers.

The high-speed printer is connected with the invoice printing server to complete the printing of the invoice. High-speed printers are one or more local high-speed printers and network high-speed printers. Multiple high-speed printers can be connected to the same print server at the same time; each high-speed printer corresponds to a print queue in the RabbitMQ request queue.

The invoice platform is used to store all generated invoice information and provide invoice query and management functions. Including: storing all the invoice information that has been generated; providing an invoice information query interface for the print server to return the complete invoice information; managing all the invoice information that has been generated. A list of generated invoices is also provided for the printing terminal.

This application mainly includes two processes of a print request production module and a request consumption module, and the specific printing process is shown in FIG. 2 .

The process of the print request production module is as follows:

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

2) Customers can choose a single invoice to associate with a printer information to generate a print request;

3) You can also select multiple invoices to associate with a printer information to generate a print request;

4) The printing terminal is connected to the print server, and sends the print request to the print server;

5) The print server forwards the print request to different print queues according to the name of the printer in the print request and waits for printing.

The process of print request consumption module is as follows:

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;

2) The consumer thread first determines whether the corresponding printer is idle, and if the printer is idle, it takes the first request of the print request queue. If the print queue is empty at this time, repeat step 2) after the processing thread sleeps for a period of time;

3) When the consumer thread obtains a single invoice printing request, the complete invoice information can be obtained by requesting the invoice platform once;

4) When the consumer thread obtains a batch invoice printing request, it can request the invoice platform to obtain the complete invoice information in batches multiple times.

5) Generate invoice printing information according to the invoice information, and send it to the corresponding printer for printing

6) Record the invoice printing log, and feedback the invoice printing result information to the invoice platform

7) Determine whether the system exits, and repeat steps 2) to 6) if the execution continues, and multiple print queues process the invoice printing request of the printing terminal concurrently.

This application uses the RabbitMQ message queue to store and process print requests sent by the print terminal, realize the decoupling of the print terminal and the print server, and process requests asynchronously, thereby relieving the pressure of the system during peak periods and effectively improving system stability and invoice printing efficiency. The print server communicates with the network interface, which can flexibly access the business invoice platform of the enterprise. Invoices with large data volume correspond to multiple printers in batches, and can seamlessly connect with various existing printing equipment of the enterprise, which improves the reusability of the printing equipment. This reduces the complexity of equipment maintenance.

The present application provides a high-performance invoice printing system, including: a printing terminal, used for sending a printing request, and displaying a list of invoices and printers that have been generated in the invoice platform; a printing server, which adopts the RabbitMQ message queue to receive and store the invoice printing request, according to the The invoice printing request queries the invoice platform and downloads the detailed information of the invoice; the high-speed printer is connected with the invoice printing server to complete the printing of the invoice; the invoice platform is used to store all the invoice information that has been generated, and provides the function of invoice query and management. On the basis of separation from the printing function, the printing request production module and consumption module of the RabbitMQ message queue are used to realize efficient printing, which is no longer limited to the mode of generating an invoice and printing an invoice in the existing printing system, which simplifies the printing of invoices for enterprises. The process shortens the waiting time for customers to receive invoices and improves the work efficiency of enterprises. It solves the problem that the existing technology has low invoice printing efficiency and cannot adapt to the invoice printing application scenarios of large enterprises and high concurrency.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should Modifications or equivalent replacements are made to the specific embodiments, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention shall all be included in the scope of the claims of the present invention.
