[0031] Exemplary method

[0032] An embodiment of the present application provides a method for printing a waybill, which is applied to a terminal device. The terminal device includes: a mobile phone, a laptop, a desktop computer, a smart wearable device, etc. This embodiment takes the application to a computer as an example for illustrative purposes. Among them, the method for printing the waybill can be executed through an application installed on the computer, but it is not limited thereto. As shown in Figure 2, the method for printing the waybill may include:

[0033] Step S201: Obtain the waybill data of the waybill to be printed.

[0034] In this step, the waybill to be printed is the waybill that needs to be printed. Among them, the waybill can be an express waybill, that is, a document used in the express industry to record relevant information such as the sender, recipient, and product weight and price during the process of transporting goods. It can be understood that in some scenarios, according to specific business requirements, a waybill that can meet the business requirements can be designed, and then the designed waybill can be printed and used in specific businesses. The waybill that can meet the business requirements during this process is the waybill to be printed. For example, when sending a certain express item, an express waybill containing information such as the recipient, sender, recipient address, and sender address is required. Correspondingly, this express waybill is the waybill to be printed. After it is designed and printed, it can be pasted on the express item to enter the subsequent logistics transportation link.

[0035] The waybill data is the data contained or required to be contained in the waybill to be printed, and can also be regarded as another representation of the waybill to be printed. For example, the recipient, sender, recipient address, sender address, etc. in the express waybill can all be regarded as waybill data. In the embodiment of the present application, the specific data content of the waybill data is not limited.

[0036] Step S202: Send the waybill data to the server so that the server generates a print description of the waybill to be printed according to the waybill data and sends the print description to the terminal device.

[0037] In this step, the server is an electronic device communicatively connected to the terminal device. The terminal device and the server can achieve data interaction through wired or wireless means. For example, both the terminal device and the server are connected to the Internet, so that the two can achieve data interaction through the Internet.

[0038] It should be noted that the print description is the label data described in the print language, that is, the print language representation of the label to be printed. That is to say, for a device that can recognize the print language, it can recognize the label data / the label to be printed from the print description and perform printing. Among them, the print language is the native language that the printer can recognize. For example, the print language can be ZPL (Zebra Printer Language), PCL (Printer Control Language), etc., but not limited to this.

[0039] In this embodiment, the server is integrated with a preset translation function, which can translate the data into the representation of the print language, that is, the data described in the print language. Here, the terminal device can obtain the print description of the label to be printed by means of the translation function of the server. Specifically, the terminal device can call the interface provided by the server, use the label data as a parameter of the request, and send it to the server together with the request. The server will generate the print description of the label to be printed in response to the request and return the print description to the terminal device.

[0040] Step S203: Receive the print description returned by the server and send the print description to the printer so that the printer prints the label to be printed based on the print description.

[0041] In this step, the terminal device is communicatively connected to the printer. Among them, the connection method between the terminal device and the printer can be a wired connection, a wireless connection or other connection methods, and the embodiments of the present application do not make any limitations in this regard. It can be understood that the terminal device can control the printer to perform printing by transmitting data to the printer. Since the print description is the label data described in the print language, the printer can quickly recognize the print description to obtain the label data and print the label to be printed according to the label data.

[0042] It should be noted that if the print description returned by the server is not received for a long time or other data returned by the server is received, and this other data indicates that the server fails to generate a print description according to the label data. At this time, the local printing function of the terminal device can be selected to implement the printing of the label to be printed. Among them, the process of using the local printing function of the terminal device to implement the printing of the label to be printed can be the same as that Figure 1 shown in the process, but not limited to this.

[0043] In the embodiments of the present application, after obtaining the waybill data of the waybill to be printed, the waybill data described in the printing language is generated with the help of the server, that is, the printing description. Then, the printing description is sent to the printer, and the printer is controlled to print the waybill to be printed based on the printing description. Since the printing language is the native language that the printer can recognize. Therefore, printing the waybill to be printed according to the waybill data described in the printing language is a very efficient method, which can realize the fast printing of the waybill and no longer depends on the browser.

[0044] In some embodiments, sending the waybill data to the server includes: calling the printing interface of the operating system of the terminal device through the bridging layer, and sending the printing description to the printer, where the bridging layer is the intermediate layer between the application program and the operating system of the terminal device.

[0045] It should be noted that the printing interface of the operating system, as the native interface at the bottom layer of the terminal device, is more convenient and efficient to use. Therefore, the printing interface of the operating system can be used to print the waybill to be printed. However, the printing interface of the operating system has fixed attributes and calling rules, and not all application programs installed on the terminal device can directly call the printing interface of the operating system. Therefore, in this embodiment, a bridging layer is built between the application program and the operating system, and the bridging layer is used to realize the calling of the printing interface of the operating system by the application program.

[0046] Specifically, the bridging layer is related to the operating system, and the bridging layers under different operating systems are not the same. Here, it only needs to be ensured that the bridging layer can communicate with the application program of the terminal device and the printing interface of the operating system respectively. For example, assume that the operating system of the terminal device is the Windows operating system, and a certain application program of the terminal device can execute the above method of printing the waybill. This application program can be an application program developed based on the front-end development framework Electron. In this case, Electron is mainly based on the JS (JavaScript) language, and the JS language does not have the ability to call the printing interface under the Windows operating system. However, the C / C++ language has the ability to directly call the printing interface under the Windows operating system. Therefore, the bridging layer can be written through Node-API. Among them, Node-API is also based on the C / C++ language. Then, the application program under Electron realizes the interaction with the C / C++ language with the help of Node-API, and realizes the calling of the printing interface under the Windows operating system with the help of the C / C++ language. Finally, the application program under Electron indirectly has the ability to call the printing interface under the Windows operating system. The call chain of this process is as Figure 3As shown in the figure. The client, as an application under Electron, has its main process in the Node.js environment, so that the bridging layer can be directly written by calling the Node-API in this environment. Then, the C / C++ function module is called through the bridging layer written with the Node-API, and finally, the ability of the C / C++ language to directly call the printing interface under the Windows operating system is utilized to achieve the call of the printing interface under the Windows operating system.

[0047] In the embodiment of the present application, the underlying native interface of the terminal device is called to participate in the printing task, making the entire printing process more convenient and efficient.

[0048] In some embodiments, the printing interface of the operating system of the terminal device is called through the bridging layer, and the print description is sent to the printer, including: creating a new process; in the new process, the printing interface of the operating system of the terminal device is called through the bridging layer, and the print description is sent to the printer.

[0049] It should be noted that the new process is different from the main process. It is another newly created process while the main process continues to exist. For example, when the method for printing a shipping label provided in this embodiment is executed through the target application, the main process is created in the terminal device to run the target application. When the printing interface needs to be called, a new process is created, and in the new process, the printing interface of the operating system of the terminal device is called through the bridging layer, and the print description is sent to the printer. Since the printing interfaces under some operating systems are synchronous blocking interfaces, directly calling such an interface will cause the main process to block. For example, the writePrinter interface under the Windows operating system is a synchronous blocking interface. If the application directly calls this interface, it will cause the main process to block, making the application unresponsive and showing the phenomenon of "freezing". Therefore, it is necessary to implement the call of the printing interface under the operating system in the new process.

[0050] In some embodiments, the printer itself supports a queue mechanism. When the number of shipping labels to be printed is large, it is only necessary to send the print descriptions of each shipping label to be printed to the printer. These print descriptions of the shipping labels to be printed form a queue in the printer, and the printer selects each print description in the queue based on its own queue mechanism to print the shipping labels to be printed. Specifically, when processing the printing of a batch of shipping labels to be printed, such as Figure 4As shown in the figure, the processing process includes: Step S401: Each bill of lading to be printed triggers a printing task respectively. Step S402: Through the main thread request interface, the bill of lading data is obtained for each bill of lading to be printed respectively. Step S403: The main process is continued to forward the bill of lading data of each bill of lading to be printed to the server, so that the server generates a print description for each bill of lading to be printed. Step S404: A new process is created, and in the new process, the print descriptions of each bill of lading to be printed are sent to the printing module. The printing module is a functional module corresponding to the native printing interface of the hardware device. Step S405: In the new process, the print descriptions of each bill of lading to be printed are transmitted to the printer queue. The printer prints the bills of lading to be printed indicated by the print descriptions in the printer queue based on the queue mechanism.

[0051] In the embodiment of the present application, by calling the printing interface of the operating system in the new process, the blockage caused by the printing interface can be avoided.

[0052] In order to ensure that the printer can recognize the print description returned by the server, in some embodiments of the present application, before sending the bill of lading data to the server, the method further includes: obtaining the current print identifier; wherein, the current print identifier is the printer identifier of the printer currently connected to the terminal device; sending the bill of lading data to the server, so that the server generates a print description of the bill of lading to be printed according to the bill of lading data, including: sending the current print identifier and the bill of lading data to the server, so that when the current print identifier is the target identifier, the server generates a print description of the bill of lading to be printed according to the bill of lading data; wherein, the target identifier is the printer identifier of at least one pre-configured printer.

[0053] It should be noted that the printer identifier includes but is not limited to the driver name of the printer driver. For example, it can also be the name, model, etc. of the printer. It can be understood that the printing languages of different printers are not the same. In order to ensure that the printer receiving the print description can recognize the print description, it is necessary for the server to generate a print description that the printer can recognize according to the bill of lading data. That is, it is necessary for the server to adapt to the printer / printing language. However, the more printers / printing languages the server adapts to, the more complex the server is and the greater the pressure is. Therefore, only a small number of printers / printing languages can be adapted in the server. In this embodiment, the printer identifiers of the printers adapted by the server can be stored in a fixed storage location of the server in advance. When a print description needs to be generated, the printer identifier in the fixed storage location is used to determine whether the printer currently connected to the terminal device has been adapted in the server. Only for the printers that have been adapted, a print description is generated. In some embodiments, printers with strong versatility or wide use can be adapted in the server. The printer identifiers of these printers are stored in the server as the target identifier.

[0054] In the embodiments of the present application, a print description is generated only for the printers adapted in the server, so as to ensure that the printers can recognize the print description returned by the server.

[0055] In some embodiments of the present application, obtaining the waybill data of the waybill to be printed includes: receiving the target input of the user on the waybill printing page; in response to the target input, determining each constituent element of the waybill to be printed and the attribute information of each constituent element, and determining the constituent elements and the attribute information of each constituent element as the waybill data of the waybill to be printed.

[0056] It should be noted that the target input includes inputs such as clicking, swiping, and long pressing, but is not limited thereto. When executing the method for printing a waybill provided in this embodiment through the application installed on the terminal device, the waybill printing page is the page in the application for receiving waybill data. The constituent elements of the waybill to be printed are the elements that make up the waybill to be printed. For example, recipient information, sender information, recipient address information, sender address information, boxes, barcodes, etc., but are not limited thereto. The attribute information includes the coordinates, data type, font, color, paragraph format, etc. of the element, and is also not limited thereto.

[0057] In one embodiment, the waybill printing page includes a plurality of page elements, and each page element corresponds to a constituent element of the waybill to be printed. The user can input specific data in the page element. The application determines the input data as each constituent element of the waybill to be printed and the attribute information of each constituent element.

[0058] In the embodiments of the present application, the user can determine the waybill data of the waybill to be printed according to their actual needs, improving the flexibility of waybill printing.

[0059] See Figure 5 , which is a schematic diagram of the actual application of the method for printing a waybill provided in the embodiments of the present application. Among them, the parties involved in the printing process are the user, the client, the Node-API module, the C / C++ module, and the printer respectively. The client is a desktop application installed on the terminal device, and it is an application program developed based on the front-end development framework Electron. The operating system of the terminal device is the Windows operating system. The Node-API module is a bridging layer implemented based on Node-API, and the C / C++ module can directly access the native interfaces of the Windows operating system.

[0060] After the user triggers printing, the client will call the cloud printing instruction interface and send the waybill data of the waybill to be printed to the cloud printing platform. The cloud printing platform is equivalent to the server in the above embodiments, can generate the print description of the waybill to be printed, and the generation process is the same, which will not be elaborated here. It can be understood that the print description can be the waybill data described by ZPL, and can also be called a printing instruction. For example, the print description can be: ^MMT; ^CW0,E:MHEIGB18.TTF; ^CI26; ^CF0^FS; ^LH0,0; ^PW596, etc. The explanations of each statement in the print description are: set the label rotation mode to "rotate 90 degrees"; set not to perform a cleaning operation; set the character set to ISO-8859-1; clear the current font format setting; set the origin coordinates of the printing position to the upper left corner (0,0); set the printing width to 596 units.

[0061] After the client receives the printing instruction from the cloud printing platform, it starts a new process, and in the new process, calls the printing interface of the operating system through the bridging layer to send the printing instruction to the printer. The printer prints based on the received printing instruction and returns a prompt of successful printing to the user after printing is completed.

[0062] In the embodiments of the present application, by introducing the Node-API module and the C / C++ module to call the underlying printing interface of the Windows operating system, the printing efficiency and stability can be improved. At the same time, printing supporting facilities can be integrated, including online / offline status, printing preferences, etc. Further, combined with the printer language ZPL instruction, the waybill offset problem can be optimized.

[0063] As Figure 6 shown, the embodiments of the present application also provide a method for printing a waybill, which is applied to a server. The method for printing a waybill includes:

[0064] Step S601: Receive the waybill data of the waybill to be printed sent by the terminal device.

[0065] Step S602: Generate a print description of the waybill to be printed based on the waybill data, where the print description is the waybill data described by the printing language.

[0066] Step S603: Send the print description to the terminal device so that the terminal device controls the printer to print the waybill to be printed based on the print description.

[0067] It should be noted that for the terminal device, the waybill to be printed, the waybill data, and the print description, reference can be made to the relevant descriptions in the embodiments of the method for printing a waybill applied to the terminal device above. This will not be elaborated here. It should be noted that this embodiment is the execution process on the server side during the process of printing a waybill.

[0068] In the embodiments of the present application, after receiving the waybill data of the waybill to be printed, waybill data described in the printing language is generated, that is, the printing description. Then, the printing description is sent to the terminal device, so that the printer prints the waybill to be printed based on the printing description. Since the printing language is the native language that the printer can recognize. Therefore, printing the waybill to be printed according to the waybill data described in the printing language is a very efficient way, which can achieve the fast printing of the waybill and no longer depends on the browser.

[0069] In some embodiments of the present application, in order to ensure that the printer can recognize the printing description returned by the server, before generating the printing description of the waybill to be printed based on the waybill data, the method further includes: receiving a current printing identifier sent by the terminal device; wherein, the current printing identifier is the printer identifier of the printer currently connected to the terminal device; generating the printing description of the waybill to be printed based on the waybill data, including: when the current printing identifier is the target identifier, generating the printing description of the waybill to be printed according to the waybill data; wherein, the target identifier is the printer identifier of at least one printer pre-configured.

[0070] It should be noted that the printer identifier includes but is not limited to the driver name of the printer driver. For example, it can also be the name, model, etc. of the printer. It can be understood that the printing languages of different printers are not the same. To ensure that the printer receiving the printing description can recognize the printing description, it is necessary for the server to generate the printing description that the printer can recognize according to the waybill data. That is, it is necessary for the server to adapt to the printer / printing language. However, the more printers / printing languages the server adapts to, the more complex the server is and the greater the pressure is. Therefore, only a small number of printers / printing languages can be adapted in the server. In this embodiment, the printer identifiers of the printers adapted by the server can be pre-stored in a fixed storage location of the server. When generating the printing description, use the printer identifiers in this fixed storage location to determine whether the printer currently connected to the terminal device has been adapted in the server. Only for the printers that have been adapted, generate the printing description. In some embodiments, printers with strong generality or wide use can be adapted in the server. The printer identifiers of these printers are stored in the server as the target identifier.

[0071] In the embodiments of the present application, the printing description is only generated for the printers adapted in the server, so as to ensure that the printer can recognize the printing description returned by the server.

[0072] Regarding the feasible execution manners and possible beneficial effects of the methods in the terminal device and the server, reference can be made to the relevant descriptions in the embodiments of the method for printing a waybill applied to the terminal device and the method for printing a waybill applied to the server above, which will not be elaborated here.
