Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The document printing system, method, computer equipment, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] This application provides a document printing system, which includes a server, a front-end browser, and a printer.

[0023] The server is used for: In response to a file printing request, obtain a list of files to be printed; group the file list according to the target information to obtain multiple file groups, and generate a task list, setting the task status of each file group in the task list to pending merging; create an asynchronous parallel merging task, and based on the task list, merge each file group according to the file order within the group; in the task list, change the task status of the merged file group to merge completed. The merged files are grouped and sent to the printer or front-end browser to print the files.

[0024] In this embodiment, for the receipt file, the business personnel trigger a batch merge download and print, generating a file print request. After receiving the file print request, the server obtains a list of files to be printed and groups the obtained file list according to at least one of the business parameters and file parameters, resulting in multiple file groups. The business parameters include, for example, customer type, and the file parameters include, for example, file size and number of pages.

[0025] The server generates a task list based on the grouping results and sets the initial task status of the task list to "pending merging". It should be noted that the task list includes multiple tasks, each corresponding to a file group, and each file group is processed independently.

[0026] Create asynchronous parallel merge tasks to merge files. These tasks merge files in the order they appear within their respective groups. After the merge is complete, change the task status of the group of files in the task list to "Merge Complete".

[0027] Furthermore, the grouped and merged files are sent to a printer or a front-end browser to print the files. In one embodiment of this application, the printer includes a single printer or a cluster of printers.

[0028] This application employs a flexible grouping and merging strategy to avoid batch printing all files, reducing the risk of file order corruption. Even if the printer does not support batch printing, it eliminates the need to open and print each file individually, saving considerable time. Furthermore, in the presence of a printer cluster, parallel printing is possible, improving printing efficiency. In addition, this application uses a parallel file merging method, reducing processing time and further enhancing printing efficiency.

[0029] Merging all files into one large file requires serial processing, which consumes more time on the server side. After being sent to the printer, it also leads to prolonged printer occupancy, preventing other critical tasks from being performed. Furthermore, it hinders the parallel printing function when a printer cluster exists. This application solves these problems by dividing the files into multiple groups.

[0030] In one embodiment of this application, the server is specifically used for: Determine if the printer supports direct access from the server; If the printer supports server access, the merged files will be sent to the printer in groups so that the printer can print the files according to the different groups. If the printer does not support server-side access, the merged file groups are sent to the front-end browser, which then sends the merged file groups to the printer so that the printer can print the files according to the different file groups.

[0031] In this embodiment, for printers that support direct server access, the server directly sends file groups to the printer to achieve printing. For printers that do not support direct server access, the file groups can be forwarded by a front-end browser to achieve printing. This embodiment can flexibly adapt to various types of printers and achieve file group printing.

[0032] In one embodiment of this application, the server is further configured to: add separator pages to the files in the file group during the process of merging file groups. For multi-page files, separator pages can be optionally added after each file, which is beneficial for file differentiation.

[0033] In one embodiment of this application, the front-end browser is used for: Retrieve the task list from the server and create download tasks based on the task list; Use a background thread to poll and obtain the task status of each file group in the task list; When the task status is determined to be merged, the download task is started to download the merged file groups in segments, and the downloaded file segments are cached in the group ID of the file group; After the file segments of a file group have been downloaded, the file segments in the cached group ID are merged. A notification message indicating that the download is complete is sent, allowing business personnel to trigger a printer connection and print command based on the notification message.

[0034] In this embodiment, the front-end browser polls to obtain the task status, enabling it to promptly understand whether file groups have been downloaded completely. For already downloaded file groups, it initiates the download task. Furthermore, this application employs a segmented download method when downloading file groups, avoiding transmission timeouts due to excessively large files. Also, if a segment fails to download due to network interruption, server failure, or other issues, only that segment needs to be re-downloaded, without affecting the integrity of other downloaded segments, thus enhancing download stability.

[0035] After the download is complete, a pop-up notification will be displayed on the page to inform the business personnel that the download is complete, so that the business personnel can trigger the printer connection and print the message.

[0036] In one embodiment of this application, the server is further configured to: Retrieve the print order settings information set by business personnel, including whether to print according to the download order or the file priority order; Set the corresponding print order identifier based on the print order setting information, and mark the print order identifier in the task list; A front-end browser, specifically used for: After obtaining the task list, control the printer to print the documents in the order indicated by the print order identifier.

[0037] In this embodiment, business personnel can set the printing order of file groups, which can be based on the download order or the file priority order. The file priority can be data preset by the business personnel. For example, the printing priority of customer type A can be set to be higher than that of customer type B.

[0038] Based on the print order settings configured by business personnel, a corresponding print order identifier is set. For example, if the print order identifier is "0", the print order will be based on the download order; if the print order identifier is "1", the print order will be based on the file priority order.

[0039] This application allows for flexible settings of the printing order of document groups to meet the printing needs of business personnel for return receipt documents.

[0040] In one embodiment of this application, such as Figure 1 As shown in the embodiment of this application, the workflow of a document printing system includes: (1) Business personnel trigger the batch merge download and print function.

[0041] (2) After receiving the request, the server obtains the list of files to be printed.

[0042] (3) The server groups the file list obtained in (2) according to business parameters (e.g., customer type) and file parameters (e.g., file size, number of pages).

[0043] (4) The server generates a task list based on the grouping results of (3), and the initial state is pending merging.

[0044] (5) The server generates a group task list based on (4), creates corresponding asynchronous parallel tasks to merge files, and the asynchronous parallel tasks merge files according to the file order within the group.

[0045] (6) During the file merging process, separator pages can be added as needed for differentiation.

[0046] (7) After the merge is complete, change the status of the corresponding task in the task list to "Merge Complete".

[0047] (8) If the printer supports server access, the server can directly call the printer through the interface to print.

[0048] (9) If the printer cannot print directly, the server needs to return the task list to the front-end browser after generating the asynchronous task.

[0049] (10) The front-end browser creates a silent download task based on the group task list.

[0050] (11) The front-end browser uses a background thread to poll and obtain the merging status of each task.

[0051] (12) When the group task is completed, start the download task to download the pieces and cache the downloaded content in the group ID corresponding to IndexDb.

[0052] (13) After each group is downloaded, retrieve the cached objects in indexDb and merge them.

[0053] (14) Use a message notification on the page to pop up a window to remind business personnel that the download has been completed.

[0054] (15) Business personnel enter the list of tasks to be printed, click the print link, and print.

[0055] (16) The printer prints according to different groups.
