Description

Technical Field

[0001] This disclosure relates to the field of digital printing technology, and in particular to a printing control method, apparatus, electronic device, and computer-readable storage medium. Background Technology

[0002] In organizations with confidentiality requirements, document printing typically requires approval and management. Current technology includes manual management where, when a user needs to print a document, it is first sent to a supervisor for approval. Once approved, the network administrator is notified, who then manually grants the user printing permissions. This method is not only time-consuming and labor-intensive but also fails to provide statistical management of printed documents. Besides manual methods, some organizations use pre-disabling the printer to facilitate print approval. However, this method is easily altered, or the printer may not be disabled after a print operation, thus failing to effectively guarantee the approval and management of print operations.

[0053] Please see Figure 1 This disclosure provides a printing control method applicable to a client, comprising the following steps:

[0054] S100: Monitors all currently networked printers in real time at a preset frequency and sets the status of all printers to disabled.

[0055] This embodiment of the disclosure uses a polling thread to monitor the status of all printers in the current network in real time, determining whether they are enabled or disabled. When any printer is found to be enabled, it is immediately disabled. The purpose of this polling thread is to ensure that all printers are unavailable before printing is permitted, preventing users from printing documents without authorization. The monitoring frequency of the polling thread can be set based on experience, the number of printers, the number of computers connected to the printers, the number of users, etc., for example, using intervals of 1 second, 30 seconds, 1 minute, or 5 minutes. This embodiment of the disclosure does not impose any limitations on this.

[0056] It should be noted that, if not stopped, the polling thread in this embodiment can run continuously for 24 hours, thereby ensuring that unauthorized printers are always disabled. By setting a polling thread to keep unauthorized printers disabled, users can be prevented from printing paper documents without authorization, effectively improving security and preventing leaks.

[0057] S200: In response to a file upload command sent by the user, receive the first document to be printed and printing parameters through the virtual printer interface; the file upload command includes user identification information.

[0058] When a user wants to print a target document, such as the first document, they must first upload the first document to the reviewer for approval. Users can send file upload instructions, the first document to be printed, and printing parameters through a unified virtual interface. This virtual interface can be a virtual printer interface, allowing all users on the network to initiate the printing process and enter the file upload interface. The purpose of setting up a unified virtual printer interface in this embodiment is to achieve unified management of all printed files. Through this virtual printer interface, information on all documents printed in a historical period can be obtained, making the source of each paper document traceable, thereby improving the security of confidential documents. Furthermore, the file upload instruction in this embodiment may include user identification information, sending time, etc. The first document to be printed may include any format of document or image, such as .doc, .pptx, .jpg, etc., and the printing parameters may include the number of copies, paper size, scaling requirements, etc.

[0059] S300: Upload the first document to the reviewer for review.

[0060] After the user loads or enters the above content and clicks the "Start Upload" button, the corresponding file upload instructions, the first document to be printed, and printing parameters will be sent to the corresponding reviewer. This embodiment of the disclosure can pre-store the correspondence between different users and different reviewers, such as the correspondence between user identification information and reviewer identification information. Thus, when the user clicks the "Start Upload" button, the relevant content is automatically sent to the corresponding reviewer. Of course, depending on different application scenarios, users can also manually specify other reviewers; this embodiment of the disclosure does not limit this. In one embodiment, this step can convert the format of the first document, for example, converting .doc, .pptx, .jpg, etc., to a unified PDF format, thereby facilitating reviewer viewing and improving review efficiency.

[0061] S400: In response to the approval instruction sent by the reviewer, print task information is sent to the user.

[0062] Once the reviewer receives and approves the first document and other content uploaded by the user, it will send an approval instruction to the client of this disclosure. Based on the received approval instruction, this embodiment generates a print job initiated by the user, allowing the user to print the first document using their local computer.

[0063] 500: Receive the start printing command sent by the user based on the print task information, and enable one of the printers to print the first document according to the print parameters.

[0064] Print job information is issued to the user after the initial uploaded document has been approved. It can be understood that print job information can include one or more documents. If a user has issued multiple file upload commands and uploaded multiple initial documents, a corresponding print job information will be generated for each initial document after approval. Based on this, the user can select one of the print job information to perform the print operation. Through this step, the printer corresponding to each initial document is also traceable; in other words, the paper output from each printer is traceable. This prevents leaks due to using the wrong printer. Figure 2 This is a schematic flowchart illustrating the printing of a first document provided for an embodiment of this disclosure. Figure 2 As shown, step S500 includes:

[0065] S510: Change the status of the target printer corresponding to the printer identifier from disabled to enabled.

[0066] As mentioned above, step S100 sets the status of all currently networked printers to disabled via a polling thread. Therefore, before printing begins, the status of the target printer needs to be changed from disabled to enabled. Specifically, the polling thread mentioned in step S100 can be stopped, and the status of the target printer can be modified. In this embodiment, the target printer can be a pre-specified fixed printer. For example, if there is only one printer currently connected to the network, then the target printer is that single printer. If there are multiple printers currently connected to the network, the allowed printer identifier can be sent to the user in advance via a method specified by the server. The server can store the mapping relationship between different user identifiers and different printer identifiers. The server can determine the corresponding printer identifier by retrieving the current user identifier information and send it to the user. In summary, before step S510, the process may also include a step where the client sends the aforementioned user identifier information, the first document, and printing parameters to the server, and the client receives the printer identifier corresponding to the user identifier information returned by the server. This strengthens the monitoring of printed documents, allowing for the tracking of which printer each document was printed from, which is beneficial for unified deployment and management.

[0067] S520: Print the first document using the target printer according to the printing parameters.

[0068] This step is the same as existing technology, such as calling the CUPS printing service to perform the actual printing operation through a physical printer, and the process will not be described in detail here.

[0069] S530: If the first document has been printed, change the status of the target printer from enabled to disabled.

[0070] After a document is successfully printed, the Cups printing service will return a printing completion message. Based on this, the embodiments of this disclosure can enable the polling process mentioned in step S100 to set the status of all printers in the current network to disabled.

[0071] Through the above steps, this embodiment of the disclosure completes the automatic upload, approval, and targeted printing process of the first document, enabling unified management and monitoring of document printing and ensuring the security of classified documents.

[0072] Furthermore, embodiments of this disclosure can also add identifiers or effects to the first document to be printed to improve the recognizability of the printed paper, facilitate paper tracking, and prevent leakage. In one example, an embodiment of this disclosure further includes the following step before step S500:

[0073] The system receives barcode or watermark information corresponding to the first document from the server. The barcode information can be a unique identifier randomly generated by the server to trace the whereabouts of each printed document; the watermark information can be information with the word "Confidential" or the company logo, company name, etc., as a cover or base layer to improve the identifiability of confidential documents.

[0074] Based on the above, the client in this embodiment processes the first document according to the received barcode information or watermark information to add the barcode information or watermark information to the first document. This ensures that the printed first document has the preset effect, thereby improving the security of the paper document.

[0075] Figure 3 Another schematic flowchart of the printing control method provided in the embodiments of this disclosure.

[0076] like Figure 3 As shown, the printing control method provided in this embodiment includes the following steps:

[0077] S100': Receives user identification information, the first document to be printed, and the corresponding printing parameters sent by the client;

[0078] S200': Find the printer identifier corresponding to the user identifier information according to the preset mapping relationship;

[0079] S300': Send the printer identifier to the client.

[0080] S400': Determine the barcode information or watermark information corresponding to the first document;

[0081] S500': Send the barcode information or watermark information to the client.

[0082] Through the above steps, this embodiment of the disclosure can achieve unified storage and management of user identification information, the first document, and printing parameters on the server side, accurately recording the printing status of each classified document. Furthermore, by adding barcode or watermark information to classified documents, the traceability of printed paper can be achieved, the identifiability of classified documents can be improved, and the security of classified documents can be ensured.
