Description

Printing method, electronic equipment and system

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to a printing method, electronic equipment and a system.

Background

Currently, printers are increasingly used by users. The user can control the networked printer to execute the print job through electronic equipment such as a mobile phone. The current printing scene can be divided into local printing and remote printing according to whether the mobile phone and the printer are in the same local area network. The local printing means that the mobile phone and the printer are located in the same local area network, for example, the mobile phone and the printer are connected with the same router. Remote printing means that the mobile phone and the printer are located in different networks, for example, the mobile phone is located in a company, connected to the company's network, the printer is located in a home, and connected to the home network.

For a remote printing scenario, in some current schemes, as shown in fig. 1A, a printer in a user's home is connected to the internet (internet) through a router, and a mobile phone in a company may send a file to be printed (such as a picture or a document) to the printer in the home through a cloud (which may be called a printing cloud). However, this solution requires that the printer support the remote printing function, otherwise the mobile phone cannot send the file to be printed to the remote printer.

In other arrangements, if the printer does not support the remote printing function, the user may effect remote printing by purchasing a print cartridge (also referred to as a print cloud cartridge). As shown in fig. 1B, in order to enable a printer that does not support the remote printing function to implement remote printing, a print cloud box may be added to the network, and the print cloud box controls the printer to implement printing. However, in this scheme, networking is complicated.

Detailed Description

The technical solutions in the embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application. In the description of embodiments of the application, the terminology used in the embodiments below is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" means one or more than two (including two).

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise. The term "coupled" includes both direct and indirect connections, unless stated otherwise. The terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the embodiments of the present application, the "user" is not limited to the owner of the electronic device or a particular user, but may be an animal, hard object, or other object. The user's manipulation of the electronic device may also be manipulation of the electronic device by an animal, hard object, or other object. The use of words "user" or "user action" and the like are intended to be illustrative of, and in particular, who performs the action, and embodiments of the present application are not limited.

The printing method of the embodiment of the application can be applied to a printing system. An example of a printing system to which the technical solution of the embodiment of the present application is applied is shown in fig. 2. The system comprises a first electronic device 100, a second electronic device 200 and a third electronic device 300.

Wherein the first electronic device 100 may be located within a first network. Alternatively, the first network may be any network that may be used. Such as a cellular network, or a wireless high-fidelity (wireless fidelity, wi-Fi) network.

An application (may be simply referred to as a print application) for controlling a print job may be installed in the first electronic device 100, and the application may interact with a message (may be simply referred to as a print protocol message, or a print service message, or a print message) related to a print protocol with the second electronic device 200 through the third network. Alternatively, the first electronic device 100 may be, but is not limited to being: electronic devices such as cell phones, tablet computers, notebook computers, ultra-mobile personal computer (UMPC), handheld computers, netbooks, personal digital assistants (personal digital assistant, PDA), etc., as embodiments of the present application are not limited in this respect.

In some embodiments, the first electronic device 100 may also be a server.

Optionally, the third network comprises a wide area network. Optionally, a server may be disposed in the third network. The server may be the same as or different from the manufacturer of the first electronic device 100 and the second electronic device 200. In some examples, the user may backup portions of the data in the first electronic device 100, upload to a server, and the server may store the backup data. Subsequently, when the first electronic device 100 receives a print instruction for the target data input by the user, the server may be instructed to transfer the target data stored by the server to a remote printer, so as to implement remote printing of the printer. In other examples, after receiving a print instruction for target data input by a user, the first electronic device 100 sends print data (such as a picture to be printed) to a server in the third network, and the server does not store the print data, but directly sends the print data to the printer through the router. Alternatively, in some possible scenarios, the server for holding the user print data and the server for sending the print data to the printer via the router may be different.

Optionally, the printing protocol includes, but is not limited to, internet printing protocol/multicast Domain name System (internet printing protocol/multicast domain name system, IPP/mDNS).

The second electronic device 200, the third electronic device 300 are located within a second network. Alternatively, the second network may be any local area network that may be used, such as a Wi-Fi network.

The second electronic device 200 may be a device that provides networking functionality for the third electronic device 300. In some examples, the second electronic device 200 is configured to receive a related message of a printing protocol (which may be simply referred to as a printing protocol message, or a printing service message, or a printing message) from the printing application, and send the printing message to the third electronic device 300. Alternatively, the second electronic device 200 may be, for example, a wireless router, a customer premises equipment (Customer Premise Equipment, CPE), or the like.

Optionally, the print message includes a message corresponding to the print instruction (may be simply referred to as a print control message), and/or a message of print data. The message corresponding to the print instruction may also be referred to as a print control message, and may be used to set a print parameter of the third electronic device 300. The message of the printing data is the message of the file to be printed.

The third electronic device 300 is configured to receive a print message from the first electronic device 100 through the second electronic device 200, and execute a print job of a document to be printed according to the print message. Optionally, the third electronic device 300 is a printer, which may or may not support the remote printing function.

The printer supports a remote printing function, namely the printer supports to directly acquire the file to be printed from the printing cloud. For example, in the printing scenario shown in fig. 1A, if the printer supports the remote printing function, the printer may directly obtain the file to be printed from the printing cloud, and then the printer performs a print job for the file to be printed.

The printer does not support the remote printing function, which means that the printer does not support directly acquiring the file to be printed from the printing cloud. As one solution, as in fig. 1B, a print cloud box is introduced in the networking, and a file to be printed is acquired and stored from the print cloud by the print cloud box and forwarded to the printer. The print cloud box needs to register with the print cloud, and the registration modes include, but are not limited to, code scanning registration and the like. In this way, the operation complexity of the user is improved and the user experience is poor in the process of realizing remote printing by means of the printing cloud box.

Alternatively, the first network and the second network may be networks supporting the same or different protocols. Illustratively, the first network is a cellular data network and the second network is a Wi-Fi network.

By way of example, fig. 3 shows a schematic structural diagram of the first electronic device 100. The first electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (universal serial bus, USB) interface 130, a charge management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a sensor module 180, keys 190, a motor 191, an indicator 192, a camera 193, a display 194, a subscriber identity module (subscriber identification module, SIM) card interface 195, and the like.

The processor 110 may include one or more processing units, such as: the processor 110 may include an application processor (application processor, AP), a modem processor, a graphics processor (graphics processing unit, GPU), an image signal processor (image signal processor, ISP), a controller, a video codec, a digital signal processor (digital signal processor, DSP), a baseband processor, and/or a neural network processor (neural-network processing unit, NPU), etc. Wherein the different processing units may be separate devices or may be integrated in one or more processors.

The controller can generate operation control signals according to the instruction operation codes and the time sequence signals to finish the control of instruction fetching and instruction execution.

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Repeated accesses are avoided and the latency of the processor 110 is reduced, thereby improving the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The interfaces may include an integrated circuit (inter-integrated circuit, I2C) interface, an integrated circuit built-in audio (inter-integrated circuit sound, I2S) interface, a pulse code modulation (pulse code modulation, PCM) interface, a universal asynchronous receiver transmitter (universal asynchronous receiver/transmitter, UART) interface, a mobile industry processor interface (mobile industry processor interface, MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (subscriber identity module, SIM) interface, and/or a universal serial bus (universal serial bus, USB) interface, among others.

The I2C interface is a bi-directional synchronous serial bus comprising a serial data line (SDA) and a serial clock line (derail clock line, SCL). In some embodiments, the processor 110 may contain multiple sets of I2C buses. The processor 110 may be coupled to a touch sensor, charger, flash, camera 193, etc., respectively, through different I2C bus interfaces. For example: the processor 110 may be coupled to the touch sensor through an I2C interface, so that the processor 110 and the touch sensor communicate through an I2C bus interface to implement a touch function of the electronic device.

The MIPI interface may be used to connect the processor 110 to peripheral devices such as a display 194, a camera 193, and the like. The MIPI interfaces include camera serial interfaces (camera serial interface, CSI), display serial interfaces (display serial interface, DSI), and the like. In some embodiments, processor 110 and camera 193 communicate through a CSI interface to implement the photographing function of the electronic device. The processor 110 and the display screen 194 communicate via a DSI interface to implement the display functionality of the electronic device.

The USB interface 130 is an interface conforming to the USB standard specification, and may specifically be a Mini USB interface, a Micro USB interface, a USB Type C interface, or the like. The USB interface 130 may be used to connect a charger to charge an electronic device, or may be used to transfer data between the electronic device and a peripheral device. And can also be used for connecting with a headset, and playing audio through the headset. The interface may also be used to connect other electronic devices, such as AR devices, etc.

It should be understood that the connection relationship between the modules illustrated in the embodiments of the present application is only illustrative, and does not limit the structure of the electronic device. In other embodiments of the present application, the electronic device may also use different interfacing manners, or a combination of multiple interfacing manners in the foregoing embodiments.

The charge management module 140 is configured to receive a charge input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charge management module 140 may receive a charging input of a wired charger through the USB interface 130.

In other embodiments of the application, the electronic device may include more or less components than illustrated, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Embodiments of the application are configured in a layered mannerThe system is an example illustrating the software architecture of the electronic device 100.

Fig. 4 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of applications.

As shown in fig. 4, the application program may include APP (application) for a call, a memo, a browser, a contact, a camera, a gallery, a calendar, a map, bluetooth, music, video, a short message, and the like.

In some embodiments of the application, the applications may also include applications related to print jobs, such as applications for controlling execution of print jobs. Alternatively, the application for controlling the print job may be pre-installed when the first electronic device 100 leaves the factory, or may be downloaded and installed from an application market when the user uses the first electronic device 100, which is not limited in the embodiment of the present application.

Each print service has a corresponding service name (or package name), e.g., forSystem, print service name is hwprintservice, for native +.>The name of the print service is builintin printservice. The implementation protocol of the print service may be, but is not limited to, IPP/mDNS.

The framework layer may also provide virtual private network (virtual private network) services (or VPN tunnels). The application program can call VPN service to intercept print message from kernel layer. The application may then send the intercepted print message to the second electronic device 200 to cause the second electronic device 200 (e.g., a router) to forward the print message to the third electronic device 300 (e.g., a printer).

Alternatively, the print message may be a message based on any print protocol (such as IPP).

It is understood that fig. 4 is only one example of a software architecture to which the first electronic device 100 is applicable, and that some modules or functions of a layer may be implemented by one or more other layers when actually implemented.

The kernel layer is a layer between hardware and software. The kernel layer at least comprises display drive, camera drive, audio drive, sensor drive, etc., which is not limited in this embodiment of the present application.

The structure of the second electronic device 200 may also refer to the structure of the first electronic device 100 shown in fig. 3, and the second electronic device 200 may have more or fewer components than the structure shown in fig. 3, or may combine certain components, or may split certain components, or may have a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

For example, when the second electronic device 200 is a router, as in fig. 5A, the second electronic device 200 may include a processor 501, a memory 502, a transceiver 503, and the like. Wherein the transceiver 503 is used to communicate with other devices. Please refer to the description of the related structure in the first electronic device 100 of fig. 3 for other components of the second electronic device 200, which is not described herein.

The technical solution of the embodiment of the present application is described below by taking the first electronic device 100 as a mobile phone and the second electronic device 200 as a router, and taking the mobile phone and the router being located in different local area networks as an example.

Illustratively, taking an application for controlling a print job as a smart life application as an example, in response to an operation of opening the smart life application by a user, the mobile phone displays an interface 601 as shown in fig. 5B (a). Wherein interface 601 includes a card for each electronic device in the home. Wherein the card of router AA is labeled 602. If it is detected that the user clicks on card 602, the handset may jump to interface 603 as shown in fig. 5B (B). Optionally, the interface 603 may expose an access device for router AA. Optionally, the interface 603 may also include a remote print option 604. If it is detected that the user clicks on the remote print option 604, the handset may jump to the remote print interface 605 as shown in fig. 5B (c). Optionally, the interface 605 includes a local photo option 606 and a local document option 607. The local photo option 606 is used for selecting a local photo to be printed by a user, and the local document option 607 is used for selecting a local document to be printed by the user.

In some examples, if the handset detects that the user clicks on the local photo option 606 shown in fig. 5B (c), the handset may jump to the album interface 608 shown in fig. 5B (d) and the user may select a local photo to be printed from the album. In response to a user selecting a photograph to be printed, such as clicking on the photograph as shown in fig. 5B (d), the handset may jump to the remote printing interface 605 as shown in fig. 6A (a), and the handset begins to establish a remote channel (e.g., a peer-to-peer (P2P) channel) with the router. Alternatively, the handset may display a "remote channel being established …" message 609 to alert the user that a remote channel is currently being established with the router. After the handset establishes a remote channel with the router, an interface 610 as shown in fig. 6A (b) may be displayed.

Optionally, the interface may include a hint information 612 to hint that the user is currently established a remote channel with the router.

Optionally, the interface 610 may also include preview information 611 of the photograph to be printed.

Optionally, the interface 610 also includes options related to the printing function. Optionally, the printing function related options include, but are not limited to: an option 619 for selecting a printer, an option for selecting the number of print copies, an option for selecting a paper type, an option for selecting a print mode (black-and-white, color printing), an option for selecting a paper size.

Wherein, as shown in fig. 6B (a), in response to the user clicking on the option 619, the handset may display a printer selection interface 617 as shown in fig. 6B (B). If the user is detected clicking on control 618 on interface 617, the handset determines that the user wants to perform the print job this time using printer XX. Upon detecting a user clicking on control 618 on interface 617, the handset can jump back to interface 610 as shown in fig. 6B (a).

Optionally, interface 610 also includes a start print button 613. In response to the user clicking the start print button 613, the mobile phone invokes the print service provided by the system, and the print service generates a print message according to the print protocol. The handset may also invoke a VPN interface provided by the system to intercept and send the print message to the router. The printing message comprises a message corresponding to the printing instruction and a message of the file to be printed.

After receiving the print message, the router can forward the print message to the connected printer. Optionally, the message corresponding to the print instruction may carry one or more print parameters as shown in fig. 6A (b). For example, the number of copies to be printed, the paper type (plain paper), the print mode (black and white), the paper size (A4) are carried. The handset may set the one or more printing parameters for the printer via a print message.

After the printer receives the printing message from the mobile phone through the router, the printer can execute the printing task according to the printing message. Illustratively, the printer sets the paper type according to the printing parameters carried in the message corresponding to the printing instruction, and starts to print the file to be printed after the printing parameters are set.

Alternatively, in response to the user clicking the start print button 613 as shown in fig. 6A (b), the handset may jump to the remote print interface 605 and display a prompt 614 to prompt the user that a print job is currently being performed as shown in fig. 6A (c).

Optionally, after the printer finishes the print job, the printer may send a job completion response to the mobile phone through the router, to indicate that the print job has been executed. In the case where the mobile phone knows that the print job has been executed, as shown in fig. 6A (d), the mobile phone may display a prompt 615 in the interface 605 to prompt the user that the print job has been executed.

In the above technical solution of the embodiment of the present application, after receiving a print instruction input by a user, a mobile phone may establish a remote channel between the mobile phone and a router, and send a message corresponding to the print instruction and a file to be printed to a printer through the router via the remote channel. Thus, the printer can execute the print task according to the message corresponding to the print instruction and the file to be printed. Therefore, under the condition that the printer does not support the remote printing function or supports the remote printing function, the printer can receive the message corresponding to the printing instruction from the mobile phone and the file to be printed through the router and execute the printing task, so that the execution success rate of the remote printing task is improved.

In addition, in the technical scheme, under the condition that the printer does not support the remote printing function, the mobile phone can intercept the printing message and send the intercepted printing message to the printer through the router, and in the process, a printing cloud box is not required to be additionally introduced, so that the networking complexity of the home network is reduced, and the high operation complexity caused by the registration of the printing cloud box can be avoided.

It should be noted that, in fig. 6A, the remote channel with the router is set up by the mobile phone before the user clicks the "start print" button 613, and in other embodiments, the mobile phone may set up the remote channel after detecting that the user clicks the "start print" button 613, which is not limited by the embodiment of the present application.

For example, if it is detected that the user selects (e.g., clicks on) a picture to be printed in the interface 608 shown in fig. 5B (d), the mobile phone may display an interface 610 shown in fig. 6C (a), which includes a start print button 613. Upon detecting that the user clicks the start print button 613, the handset may display an interface 616 as shown in fig. 6C (b). Optionally, interface 616 may include prompt 612 for prompting the user that the handset is currently establishing a remote channel and/or that the remote channel has been established successfully. After the remote channel is established successfully, the handset may display a prompt 614 in interface 616 to prompt the user that the printer is currently printing, as shown in fig. 6C (C). After the printer has finished printing, as shown in fig. 6C (d), the mobile phone may display a prompt 615 in the interface 616 for prompting the user that the printer has finished printing.

The interaction between the above-mentioned electronic devices during printing is described below. For example, taking the first electronic device 100 as a mobile phone, the second electronic device 200 as a router, and the third electronic device 300 as a printer, the first electronic device 100, the second electronic device 200, and the third electronic device 300 satisfy the system architecture shown in fig. 2, and as shown in fig. 7, the printing method provided in the embodiment of the application includes:

s101, the mobile phone receives a printing instruction input by a user.

As one possible implementation, as shown in fig. 8a, s101 may be implemented as: s101a, the mobile phone receives a printing instruction input by a user through a printing application. Print applications include, but are not limited to, applications such as smart life related to print jobs.

In the embodiment of the application, the user can input the printing instruction in any available mode, and the printing instruction is used for instructing the mobile phone to remotely control the printer to execute the printing task. Optionally, the printing instruction may be an instruction input by a user through an interface, or may be a voice instruction input by the user, and the embodiment of the present application does not limit the form of the printing instruction.

For example, the user may input a voice "let a printer at home print a picture a in a album of a mobile phone" through a voice assistant, and the voice may be used as a print instruction.

As further illustrated in fig. 6A (b), the smart life application receives an operation instruction by which the user clicks the "start print" button 613, which may be a print instruction.

S102, the mobile phone generates and intercepts the printing message.

After the mobile phone detects the printing instruction, a printing message can be generated so as to control the remote printer to execute the printing task. The print message includes a message corresponding to the print instruction (i.e., a print control message) and a message of the document to be printed (i.e., a print data message). Alternatively, a file to be printed may be encapsulated into one or more messages according to a printing protocol.

As one possible implementation, as shown in fig. 8A, S102 may be implemented as: s102a, the printing application calls the printing service provided by the mobile phone system, and S102b, the printing service generates a printing message. After that, the print service may also execute step S102c to transfer the print message to the kernel. In the related art, the handset may forward the print message to other devices through the kernel (such as forwarding based on the print protocol in the mDNS local area network), but the forwarding process is generally limited to forwarding in the same local area network. That is, the handset needs to be within the same local area network as the receiving device. In the embodiment of the application, in order to enable the mobile phone to send the printing message to the remote equipment, the mobile phone can intercept the printing message generated by the kernel into the printing application and establish the remote channel between the printing application and the remote router, so that the printing message can be sent to the remote router through the printing application, and the remote printing is realized.

As a possible implementation manner, as shown in fig. 8A, the mobile phone intercepts the print message generated by the kernel, which may be implemented as the following steps S102d-S102g:

s102d, the printing application calls VPN service;

s102e, the VPN service sends an interception request to the kernel, wherein the interception request is used for requesting interception of the printing message.

After receiving the interception request, the kernel determines that one or more printing messages in the current printing task need to be sent to the VPN service. Then, after the kernel receives the print message of the current print job from the print service, the print message needs to be forwarded to the VPN service.

S102f, the kernel sends a printing message to the VPN service, and the VPN service intercepts the printing message from the kernel.

As a possible implementation manner, after the kernel receives a certain type of message from the print service, the kernel can identify that the message is a print message through the service name (or packet name) of the message. And then, the kernel intercepts the printing message and sends the printing message to VPN service.

S102g, the VPN service transmits the intercepted printing message to the printing application.

Alternatively, the VPN service may be implemented by a related technology. Exemplary, for installation ofThe VPN service can be realized based on the vpnservice interface of the mobile phone of the system.

It should be noted that, the embodiment of the present application is not limited to the execution sequence of generating and intercepting the message of the print instruction and the message of the file to be printed.

S103, a remote channel is established between the mobile phone and the router.

As one possible implementation, as shown in fig. 8a, s103 may be implemented as: s103a, the mobile phone establishes a remote channel between the printing application and the router. Optionally, the remote channel is used to transmit print messages between the printing application and the router.

Optionally, the remote channel includes, but is not limited to, a P2P channel. Optionally, the P2P channels include, but are not limited to, P2P channels based on network address translation (session traversal utilities for nat, stun) technology of session traversal application, P2P channels based on network address translation (traversal using relays around nat, turn) technology of relay traversal.

For example, if a P2P channel based on turn technology is established, the P2P channel may include a server for relay service. If a P2P channel based on stun technology is established, the P2P channel may not include a server for relay service, i.e. the handset and the router may be directly connected, and no other relay node exists between the handset and the router.

It should be noted that, after receiving the print command input by the user, the mobile phone may establish a remote channel with the router. For example, the mobile phone establishes a remote channel after detecting that the user clicks the start print button 613 as shown in (a) of fig. 6C. Alternatively, the handset may pre-establish a remote channel with the router prior to receiving the print instructions entered by the user. For example, the mobile phone establishes a remote channel in advance before detecting that the user clicks the start print button 613 as shown in (b) of fig. 6A. The embodiment of the application does not limit the establishment time and the specific establishment mode of the remote channel.

S104, the mobile phone sends a printing message to the router through the remote channel.

As one possible implementation, as shown in fig. 8a, s104 may be implemented as: and S104a, the printing application sends a printing message to the communication module of the router through the remote channel. Wherein the print message is intercepted by the print service into the print application. Alternatively, if the remote channel includes a server for the relay service, the print application may send the print message to the server first, and then the server (one example of a fourth electronic device) sends the print message to the router.

It should be noted that, the message of the print instruction and the message of the file to be printed may be sent by the same message, or may be sent by different messages. For the case of sending a message through a plurality of messages, the message of the printing instruction may be sent first, or the message of the file to be printed may be sent first, or the message of the printing instruction and the message of the file to be printed may be sent simultaneously.

Illustratively, the handset begins sending print messages to the router upon detecting a user clicking on the start print button 613 as shown in fig. 6C (a). The print message includes a print control message and a message of a document to be printed. The print control message may carry one or more print parameters (such as, but not limited to, paper type, paper size, etc.) as shown in fig. 6C (a). The message of the file to be printed may be, for example, one or more messages formed by encapsulating the picture 611 to be printed as shown in fig. 6C (a).

S105, the router sends a printing message to the printer.

As one possible implementation, as shown in fig. 8a, s105 may be implemented as: s105a, the communication module analyzes and transmits a printing message to VPN service of the router; s105b, the VPN service of the router transmits a printing message to the kernel; and S105c, the kernel calls the communication module through the corresponding drive to send a printing message to the printer.

Alternatively, the VPN service of the router may be based onIs realized by a tun interface.

S106, the printer executes the print task.

For example, as shown in fig. 6A (c), during execution of a print job by the printer, the handset may display a prompt 614 to prompt the user that the printer is printing.

And S107, the printer sends a response message to the mobile phone.

The response message is used for indicating that the printing task is completed.

As one possible implementation, the printer sends the response message to the handset through the router.

Alternatively, because the printer and router are within the same local area network, the router may interact with the printer through a kernel. Alternatively, the interaction flow between the router and the printer may follow a printing protocol (such as mDNS protocol) within the local area network.

After the router receives the response message from the printer through the kernel (corresponding to step S107a shown in fig. 8A), the router determines the identifier (such as the service name) of the response message, and sends the response message to the first electronic device according to the identifier of the response message. After receiving the response message, the router determines that the response message is a message of the printing service according to the service name of the response message, and may call the VPN service to intercept the response message (corresponding to step S107b shown in fig. 8A), where the VPN service transmits the intercepted response message to the communication module (corresponding to step S107c shown in fig. 8A), and the communication module sends the response message to the mobile phone through the remote channel (corresponding to step S107d shown in fig. 8A). Wherein the interaction between the communication module and the handset may follow IPP.

For example, after the printer has performed the print job, the instruction information may be sent to the mobile phone, and after the mobile phone receives the instruction information, and knows that the printer has performed the print job, the prompt information 615 as shown in (d) of fig. 6A may be displayed to prompt the user that the printer has completed the print job.

In the above embodiment, in the remote printing scenario, the mobile phone establishes a channel between the printing application such as smart life and the router, and transmits a printing message (including a message corresponding to a printing instruction and a message of a file to be printed) between the printing application and the router, so that the router can send the printing message to the printer, thereby realizing the function of the printer to print remote files (i.e. to print files in devices not in the same local area network). Compared with the scheme shown in fig. 1B, when the printer does not support the remote function, the file to be printed can be received from the printing cloud only by means of the printing cloud box, and networking is relatively complex, the technical scheme of the embodiment of the application can realize the remote printing function without additionally and independently setting the printing cloud box in networking, and reduces networking complexity.

In addition, in the embodiment of the application, the printing message can reach the printer through the mobile phone and the router, the number of the devices passing through the communication path is less, the transmission time delay is smaller, the transmission efficiency is higher, and the efficiency of the printing task is improved.

In addition, after the router receives the printing message from the mobile phone, the router does not need to store the printing message, so that the consumption of storage resources can be reduced.

By way of example, fig. 8B illustrates yet another method flow of an embodiment of the present application. In the process, the mobile phone sends a printing control message through the router, and then sends a file to be printed to the printer so as to control the printer to execute remote printing. As shown in fig. 8B, the method includes:

s401, the mobile phone receives a printing instruction input by a user.

S402, the mobile phone generates and intercepts a printing control message.

S403, a remote channel is established between the mobile phone and the router.

S404, the mobile phone sends a printing control message to the router through the remote channel.

Illustratively, the print control message carries one or more print parameters.

S405, the router sends a printing control message to the printer.

S406, the printer sends a first response message aiming at the printing message to the mobile phone.

Optionally, after receiving the print control message, the printer sets the print parameters according to the print control message. After the printing parameters are set, the printer can send the first response message to the mobile phone through the router, wherein the first response message is used for representing that the printing parameters are set.

This step S406 is an optional step.

S407, the mobile phone sends the file to be printed to the printer.

In some embodiments, after receiving the first response message from the printer, the mobile phone knows that the printer has set the corresponding printing parameters, and then the mobile phone issues the file to be printed to the printer.

As one possible implementation, the handset sends the file to be printed to the printer via the router. Optionally, if the remote channel between the mobile phone and the router includes a server, the mobile phone may first send the file to be printed to the server, and then the server sends the file to be printed to the printer via the router.

The process of sending the file to be printed to the printer by the mobile phone can be referred to as the process of sending the printing control message to the printer by the mobile phone. The mobile phone calls VPN service to intercept the file to be printed, and sends the intercepted file to be printed to the router through the remote channel, and the router forwards the file to be printed to the printer.

S408, the printer executes the print task.

After receiving the file to be printed, the printer executes a print job for the file to be printed.

S409, the printer sends a second response message to the mobile phone.

The second response message is used for indicating that the printing task is completed.

It should be noted that, in the embodiment shown in fig. 8B, only the mobile phone is used to send the print control message first and then send the file to be printed for illustration, and in other embodiments, the sending timing of the print control message and the file to be printed may be determined according to the need, which is not limited herein.

The embodiment of the application also provides a printing method, wherein when a user expects a remote printer to execute a printing task, a server generates a printing message to control the printer to execute the remote printing task (such as a printer in home to print a file in a remote mobile phone). For example, in some scenarios, a user selects a file (such as a photograph or document) that has been uploaded to a cloud server through a terminal, and instructs the terminal to print the selected file. In such a scenario, the terminal may instruct the server storing the file to generate a print message to control the printer to execute the print job. The flow of the method is illustrated in fig. 9A, and the method includes the following steps:

s201, the mobile phone receives a printing instruction input by a user.

The specific implementation of S201 may refer to step S101, which is not described herein.

S202, the mobile phone sends a printing instruction to a server (first electronic equipment).

Optionally, the print instruction carries an identification of the file to be printed.

As one possible implementation manner, the mobile phone detects a print instruction of a user on a target file, and if it is determined that the target file is a file that has been backed up to the server, the mobile phone sends the print instruction to the server. Optionally, the print command sent by the mobile phone may carry the identifier of the target file.

Or after detecting the printing instruction of the user on the target file, the mobile phone sends the printing instruction to the server, and the server inquires whether the target file is backed up to the server. In the case where the target file has been backed up to the server, the server may perform the following step S203. In the case where the target file is not backed up to the server, the server acquires the target file from the cellular phone and performs the following step S203.

Illustratively, as in (a) of fig. 9B, the handset displays a remote printing interface 903, the interface 903 including a "cloud photo" option 901. Upon detecting the user clicking on option 901, the handset may jump to interface 902 as shown in fig. 9B (B). The interface 902 may include pictures stored in a cloud server and uploaded by the cell phone or co-account device. Optionally, after detecting the operation of selecting one or more pictures from the cloud image library by the user, the mobile phone may jump to the interface 904 as shown in fig. 9B (c). After detecting the operation of the user clicking the start print button 613, the mobile phone transmits a print instruction to the server.

Optionally, the interface 903 may further include options for other cloud files (such as documents uploaded to a cloud server), which is not limited by the embodiment of the present application.

S203, the server generates and intercepts the printing message.

As a possible implementation, after receiving the print instruction, the server invokes a print service, and the print service generates a print message according to a print protocol (such as IPP). The server, upon receiving a print instruction (which may carry an identification of the file to be printed) from the cell phone, determines the file that the user wants to print, and encapsulates the file into one or more messages. The server may also encapsulate the print instructions into corresponding print control messages.

S204, a remote channel is established between the server and the router.

The process of establishing a remote channel between the server and the router can be referred to as a process of establishing a remote channel between the mobile phone and the router. Optionally, the remote channels between the server and the router include, but are not limited to, P2P channels.

The embodiment of the application does not limit the time for establishing the remote channel. The server may establish the remote channel after receiving the print instruction, or after the user selects the cloud file to be printed and before receiving the print instruction. Alternatively, in other embodiments, the server and router have established a remote channel prior to the current print job, and no remote channel need be established for the current print job.

S205, the server sends the printing message to the router through the remote channel.

S206, the router sends the printing message to the printer.

The specific implementation of S206 may refer to step S105, which is not described herein.

S207, the printer executes the print task.

In the implementation manner, the server and the router are used for interactively printing the message (including the printing control message and the file to be printed), so that the communication path is shortened, and the efficiency of the printing process is improved.

S208, the printer sends a response message to the server, wherein the response message is used for indicating that printing is completed.

S209, the server sends a response message to the mobile phone, wherein the response message is used for indicating that printing is completed.

The embodiment of the application also provides a printing method, wherein when a user expects a remote printer to execute a printing task, a router (such as a home) generates a printing message to control the printer to execute the remote printing task (such as a file in a mobile phone of a printing company). The flow of the method is illustrated in fig. 10, and the method comprises the following steps:

s301, the mobile phone receives a printing instruction input by a user.

The specific implementation of S301 may refer to step S101, which is not described herein.

S302, a remote channel is established between the mobile phone and the router.

The specific implementation of S302 may refer to step S103, which is not described herein.

S303, the mobile phone sends the file to be printed to the router through the remote channel.

The specific implementation of S302 may refer to step S104, which is not described herein.

S304, the router generates a printing message.

As one possible implementation, after receiving the file to be printed, the router invokes a print service that generates a print message according to a print protocol (such as IPP).

S305, the router sends a printing message to the printer.

S306, the printer executes the print task.

Therefore, according to the technical scheme of the embodiment, the printed message only needs to be interacted between the router and the printer, and is not required to be transmitted between the mobile phone and the router, so that the signaling overhead required for transmitting the message is further reduced.

It should be noted that the interface provided in the foregoing embodiments is merely exemplary, and the interface may have other designs, which are not limited in this respect.

Also, the types of files to be printed provided in the above embodiments are merely exemplary, and in other embodiments, other types of files, such as credential printing, web page printing, etc., may be included in the interface 605 shown in fig. 5B (c).

In addition, in consideration of information security, the interactive data between the electronic devices according to the embodiment of the application can be transmitted in an encryption mode or the like. For example, when the mobile phone uploads the backup data to the server, the desensitized backup data is uploaded.

S307, the printer sends a response message to the router, wherein the response message is used for indicating that the printing task is completed.

And S308, the router sends a response message to the mobile phone.

Fig. 11 shows still another flow of the printing method of the embodiment of the present application. Applied to a second electronic device, the method comprising:

s501, the first electronic equipment receives a printing instruction.

The printing instruction is used for indicating to execute a printing task.

In some examples, if the first electronic device is a device such as a terminal, the terminal receives a print instruction, which may be an operation instruction that a user clicks a "start print" button.

Optionally, before the terminal receives the print instruction, the terminal may further display a first interface; the first interface comprises one or more cards corresponding to the electronic equipment, and the one or more cards of the electronic equipment comprise the card of the second electronic equipment; detecting operation of a user on a card of the second electronic equipment, and displaying a second interface; the second interface includes an option for a print function associated with the second electronic device.

Illustratively, as in (a) of fig. 5B, the terminal may display an interface 601 (one example of a first interface), the interface 601 including a card for an electronic device such as a television, a speaker, and a card 602 for a router (a second electronic device). Upon detecting the user's operation on the router's card 602, the terminal displays an interface 603 (one example of a second interface) shown in fig. 5B (B), the interface 603 including an option 604 of a router-associated print function.

Optionally, after displaying the second interface, as in (B) of fig. 5B, if the user's operation of the option 604 of the printing function is detected, the mobile phone may display information of one or more files shown in (c) of fig. 5B. The one or more files include at least one of files local to the terminal and files backed up by the terminal on other devices, such as servers. The user may select one or more target print files from among the one or more files shown in fig. 5B (c).

The receiving a print instruction includes: an operation instruction of a user on a print control associated with the one or more target print files is received. For example, as in (b) of fig. 6A, the terminal may receive a click instruction of the start print button 613 by the user and take the click instruction as a print instruction associated with the target print file selected by the user.

In other examples, in the cloud backup scenario, if the first electronic device is a server, the first electronic device receives the print instruction, which may be that the server receives the print instruction from the terminal. The print instruction is an operation instruction associated with one or more target print files stored on the server.

Illustratively, as shown in fig. 9B, the user may select a cloud photo (one or more target print files) through the terminal and click on the start print button to trigger this print job.

S502, the first electronic device responds to the printing instruction to obtain a printing message corresponding to the printing task.

As a possible implementation manner, the first electronic device determines the identifier of the print message in response to the print instruction, and obtains the print message according to the identifier of the print message.

Alternatively, the identification of the print message may be, but is not limited to, the name of the service of the print message. After receiving the print instruction, the first electronic device may encapsulate print data (such as a picture to be printed, a document, etc.) into one or more print data packets, and encapsulate the print instruction into one or more print control packets. Optionally, the print instruction carries one or more print parameters.

S503, the first electronic device sends the printing message to a remote second electronic device.

Correspondingly, the second electronic device receives the printing message from the first electronic device at a remote location.

The printing message is used for controlling the third electronic device to execute a printing task, and the second electronic device and the third electronic device belong to the same local area network.

S504, the second electronic equipment sends the printing message to the third electronic equipment.

As a possible implementation manner, sending the print message to the third electronic device may be implemented as: and directly transmitting and forwarding the printing message to the third electronic equipment. That is, the second electronic device does not need to store the printing message, but directly forwards the printing message, so that the consumption of storage resources can be reduced, the storage space can be saved, and the printing efficiency can be improved.

S505, the third electronic device executes the printing task.

The embodiment of the application also provides a printing method, wherein the first electronic device can acquire whether the third electronic device supports the remote printing function, if the third electronic device supports the remote printing function, the printing task can be executed along the related technology, and if the third electronic device does not support the remote printing function, the printing task is executed by adopting the technical scheme of the embodiment of the application. Taking the first electronic device as a terminal, the second electronic device as a router and the third electronic device as a printer as an example, if the terminal knows that the printer supports a remote printing task, the terminal can send a printing data message to the printer through a printing cloud. If the terminal knows that the printer does not support the remote printing task, the terminal sends the printing message to the router through a remote channel between the terminal and the router.

The above-mentioned one or more interfaces are all exemplary, and other interface design manners are also possible, and the specific design manner of the interfaces is not limited by the present application, and the switching manner between the interfaces (for example, the interface may be switched by sliding up and down in the interfaces, or the interface may be switched by pressing a specific key). For example, the interface forms and operational flows presented in fig. 6A, 6B, 6C, and 9B are not limited. For example, in other embodiments, card mode may not be used. For another example, the third interface and the fourth interface may be displayed as long as the file can be selected and the print job triggered.

In some aspects, various embodiments of the application may be combined and the combined aspects implemented. Optionally, some operations in the flow of method embodiments are optionally combined, and/or the order of some operations is optionally changed. The order of execution of the steps in each flow is merely exemplary, and is not limited to the order of execution of the steps, and other orders of execution may be used between the steps.

Those of ordinary skill in the art will recognize a variety of ways to reorder the operations described herein. In addition, it should be noted that details of processes involved in a certain embodiment herein apply to other embodiments as well in a similar manner, or that different embodiments may be used in combination.
