[0018] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the sake of convenience of description, only parts related to the relevant invention are shown in the drawings.

[0019] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other. The following will describe the present disclosure in detail with reference to the accompanying drawings and in combination with the embodiments.

[0020] The technical problem to be solved by this application is specifically how to break through the permission limit and obtain the device identification information of the printer for reporting print data.

[0021] Figure 1 Disclosed is a method for obtaining device identification information. In an embodiment of the present disclosure, the method can be applied to a terminal, and the method may include:

[0022] Step S101, obtain the device identification information of the target printer through the print driver loaded on the terminal, and write the device identification information into the storage area of the terminal. The device identification information is used to indicate the device identifier of the target printer.

[0023] In this embodiment, the execution subject of the method for obtaining device identification information can obtain the device identification information of the target printer through the print driver loaded on the terminal. After that, the above execution subject can write the device identification information into the storage area of the terminal.

[0024] The device identifier is the identifier of the printer's hardware, such as the product serial number, that is, the SN (Serial Number) number, etc.

[0025] Step S102, in response to receiving a print instruction for the target printer, search for the device identification information in the storage area through the target client loaded on the terminal.

[0026] In this embodiment, when the above execution subject receives a print instruction for the target printer, it searches for the device identification information in the storage area of the terminal through the target client loaded on the terminal. Specifically, the terminal can generate a print instruction for the target printer in response to a user's print operation on the target printer.

[0027] The target client here can be a loadable and runnable entity such as an application or a small program. The target client can be loaded on the terminal in the form of installation or other forms such as a web page.

[0028] In some application scenarios, the terminal can be connected to multiple printers. If the terminal is connected to multiple printers, the terminal can obtain the device identifiers of the above multiple printers through the print driver loaded on the terminal. And the terminal can store the device identifiers of the above multiple printers in the storage area of the terminal. When the terminal receives a print operation on the target printer among the above multiple printers, it generates a print instruction for the target printer and searches for the device identifier of the target printer in the storage area through the target client loaded on the terminal.

[0029] For example: The terminal is connected to printers A, B, and C. The terminal can obtain the device identifiers of printers A, B, and C respectively through the print driver loaded on the terminal, and write the device identifiers of printers A, B, and C into the storage area of the terminal. When the terminal receives a print operation and generates a print instruction for printer A, the target client loaded on the terminal searches for the device identifier of printer A in the storage area.

[0030] Step S103: Generate a reporting message including device identification information corresponding to the target printer, and upload the reporting message to the server.

[0031] In this embodiment, the above execution entity can generate a reporting message for the target printer and upload the reporting message to the server. The target printer corresponds to the reporting message.

[0032] The generated reporting message includes device identification information. In addition, the reporting message may further include at least one of printer operation information, print software information, and user-related information. Among them, the printer operation information may be, for example, the number of prints indicated by the above print instruction. The print software information may be, for example, relevant information of a preset order printing system. Here, the order printing system may refer to any software system for printing bills. The user-related information may include the Universal Call Identifier (UCID).

[0033] In this embodiment, through the print driver, the access permission limit for the printer hardware is broken through, so as to obtain the device identification information of the printer. Moreover, while successfully reporting the printer information, the reported information is made more unique and general, and is easy to be recognized and used for subsequent analysis.

[0034] In some optional implementation manners of any embodiment of the present disclosure, writing the device identification information into the storage area of the terminal includes: associatively writing the device identification information and the printer name of the target printer into the storage area of the terminal; searching for the device identification information in the storage area includes: searching for the device identification information of the target printer through the printer name of the target printer.

[0035] In these optional implementation manners, the above execution entity can associatively write the printer name while writing the device identification information. That is, the above execution entity can associatively write the printer name and the device identification information into the storage area.

[0036] When the above-mentioned execution entity searches for device identification information, it can search for the printer name of the target printer, so as to find the device identification information associated with the printer name. In this way, the found device identification information is the device identification information of the target printer.

[0037] The terminal can associate and write the device identification information and the printer name of the target printer into the storage area of the terminal. In this way, the device identification information and the target printer are associated in the storage area. The target printer is one of the multiple printers connected to the terminal. Specifically, the terminal can read the device identification information of all printers in the storage area, and find the printer name of the target printer from the read device identification information through the printer name of the target printer. Or, the terminal can search for the device identification information of the target printer in the storage area through the printer name of the target printer.

[0038] These implementation methods can accurately match the device identification information corresponding to the printer name when searching for device identification information through the printer name. Especially when multiple printers are connected to the same terminal of the user, the above-mentioned execution entity can accurately match the device identification information corresponding to the printer used by the user.

[0039] In some alternative implementation manners of any embodiment of the present disclosure, writing the device identification information into the storage area of the terminal includes: determining whether the print driver has the write permission for the system hard disk of the terminal; in the case of determining that the print driver has the write permission for the system hard disk of the terminal, writing the device identification information of the target printer into the system hard disk of the terminal; in the case of determining that the print driver does not have the write permission for the system hard disk of the terminal, writing the device identification information of the target printer into other hard disks other than the system hard disk in the terminal.

[0040] In these implementation manners, the system hard disk here can be, for example, drive C. Other hard disks other than the system hard disk can include at least one of drive D, drive E, etc.

[0041] These implementation manners can preferentially write the device identification information into the system hard disk of the terminal, so as to ensure the reading priority and reading speed of the device identification information.

[0042] Figure 2 Show a method for obtaining device identification information according to an embodiment of the present disclosure. As Figure 2 shown, the method includes:

[0043] Step S201, obtaining the device identification information of the target printer through the print driver loaded on the terminal, and writing the device identification information into the storage area of the terminal, where the device identification information is used to indicate the device identifier of the target printer.

[0044] Step S202, in response to receiving a print instruction for the target printer, in the rendering process running on the target client, send a device identification request to the main process running on the target client.

[0045] In this embodiment, the execution subject of the device identification information acquisition method can run the main process of the target client and the rendering process for printing, and through the interaction between these two processes, realize reading the device identification information from the storage area. The rendering process refers to the process of rendering the printed picture.

[0046] Specifically, the above execution subject can confirm receiving the print instruction when detecting the user's confirmation print operation or receiving a print request sent by other electronic devices. In some application scenarios, the interface interaction process including receiving the print instruction can be carried out in the rendering process. Then, the rendering process can send a device identification request to the main process to request the device identification information.

[0047] Step S203, in response to listening for the device identification request in the main process, look up the device identification information in the storage area in the main process, and send the device identifier indicated by the device identification information to the rendering process.

[0048] In this embodiment, if the main process listens for the device identification request, it can look up the device identification information in the storage area, and then return the found device identification information to the rendering process.

[0049] Step S204, generate a reporting information including the device identification information corresponding to the target printer, and upload the reporting information to the server.

[0050] This embodiment can, through the interaction between the rendering process and the main process, read the device identification information through the main process with stronger processing capabilities, so as to realize smoothly and efficiently reading the device identification information.

[0051] In some optional implementation manners of this embodiment, the target client is developed based on a preset technology stack, and a preset operating environment is integrated in the main process of the preset technology stack; the above looking up the device identification information in the storage area in the main process may include: in the main process, call a preset interface in the preset operating environment to look up the device identification information from the storage area.

[0052] In these optional implementation manners, the target client can run on the preset technology stack. For example: the preset technology stack can be the Electron technology stack. This technology stack can integrate a preset operating environment in the main process. For example: the preset operating environment can be the node environment.

[0053] The above-mentioned execution entity can call a preset interface, namely the API (Application Programming Interface), in the main process in the preset operating environment, so as to search for device identification information in the storage area. The preset interface is used to search for device identification information in the storage area.

[0054] In these implementation manners, the reading ability of the device identification information can be given to the main thread through a preset interface in the operating environment integrated by the technology stack, so that the device identification can be successfully found in the main thread.

[0055] In some alternative implementation manners of this embodiment, the print instruction includes the current print information; the above-mentioned generation of the reporting information including the device identification information corresponding to the target printer and uploading the reporting information to the server includes: in the rendering process, extracting the current print information from the print instruction, and the current print information includes at least one of user-related information and print operation information; in the rendering process, generating the reporting information including the current print information and the device identifier, and uploading the reporting information to the server.

[0056] In these implementation manners, the above-mentioned execution entity can, in the rendering process, execute extracting the print operation information from the print instruction, generating the reporting information, and reporting the reporting information.

[0057] In some embodiments, the print operation information may include at least one of the number of prints, the printer association table, and the print software information.

[0058] These implementation manners can extract the information of the current print in the rendering process, so as to obtain real-time print information, which helps the server obtain detailed and accurate reporting information.

[0059] In some alternative implementation manners of this embodiment, the device identification information is a device identification file, and the device identification file is a variable-length character encoding file with a byte order mark; after the device identification information is searched for in the storage area in the main process, the method further includes: removing the byte order mark from the device identification file to obtain a device identifier to be processed; converting the device identifier to be processed into an array format of data to obtain the device identifier indicated by the device identification information.

[0060] In these alternative implementation manners, the above-mentioned execution entity can remove the byte order mark, and the device identification file after removing the byte order mark is the device identifier to be processed. Then, the above-mentioned execution entity can convert the device identifier to be processed into an array format of data, and the conversion result is the device identifier indicated by the device identification information.

[0061] A variable-length character-encoded file can be, for example, a UTF-8 (Unicode Transformation Format - 8-bit) file. Specifically, the byte order mark carried by the file can be a BOM (Byte Order Mark) header.

[0062] In these implementation methods, when the file has a byte order mark, the main process can remove the mark to prevent garbled characters from occurring after the device identification file is read.

[0063] As Figure 3a shown, the figure shows a schematic diagram of the application scenario of the method for obtaining device identification information in this application. The print interaction component of the rendering process in the client can receive the print instruction triggered by the user's print operation. After that, the above-mentioned rendering process can, through the Hypertext Transfer Protocol (HTTP), request the print data for the current print indicated by the print instruction. The print data here can include at least one of the printer association table and the print quantity, etc. After that, the rendering process can communicate with the main process to obtain the SN information, that is, the SN number, from the main process. The rendering process can integrate the SN information and the print data and upload the integration result to the analysis platform for operation data.

[0064] After the main process in the node running environment hears the request from the rendering process, it can determine whether it has the read and write permissions for the system hard disk. If it has, the main process can read the device identification file from the system hard disk. If not, the main process can read the device identification file from drive D. After that, the main process can perform format processing on the device identification file, such as removing the BOM header, to generate a JSON array, and this JSON array is the SN information.

[0065] The main process stores the device identification file and the relevant information of the device identification file in the file system. The file system can store at least one of the following: file read and write permissions, JSON array, device identification file, and the format of the array. In addition, the printer driver can obtain the above-mentioned SN number, as well as the internal and external network information, and store the obtained information in the file system.

[0066] As Figure 3bAs shown in the figure, a flowchart of a method for obtaining device identification information is shown. The terminal can be connected to a printer, obtain the SN information file corresponding to the printer through the print driver, and determine whether the print driver has access rights to the C drive. If it does, the terminal can write the SN information file to the C drive through the print driver. If not, the terminal can write the SN information file to the D drive. If the terminal starts to execute printing on the target printer, it can determine whether the print driver has access rights to the C drive. If it does, the target client can read the SN information files of all the connected printers from the C drive. If not, the target client can read the SN information files of all the connected printers from the D drive. Through the SN number in the SN information file, in the SN information files of all the printers, the SN information of the target printer can be matched through the printer name. The terminal can integrate the print data and the SN information and upload the integration result to the server. The server can generate a data report for the uploaded integration result.
