[0002] As the number of users using file transfer services grows, the demand for transferring files from electronic devices to portable storage devices (such as USB flash drives) during work is also increasing.

[0003] When the electronic device storing the file is not a personal computer (PC) (e.g., a mobile phone), the user needs to use a PC as an intermediary to save the file from the electronic device to the mobile storage device.

[0004] When users do not have a PC or do not wish to insert their electronic devices into an unknown third-party PC to copy files, they need to use an auxiliary hardware card reader (such as an OTG interface or Lightning interface) to transfer files from their electronic devices to a mobile storage device using a dedicated app on the electronic device that supports the hardware.

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0076] This application provides a file transfer method for transferring files from a mobile phone to a USB flash drive using a printer as an auxiliary device without a PC, as described in the existing technology.

[0077] Figure 1 This is a schematic diagram of an application scenario according to an embodiment of this application.

[0078] Terminal device 101 is a mobile phone. Users issue commands by clicking on the screen of terminal device 101, and terminal device 101 performs corresponding operations according to the commands issued by users.

[0079] In other embodiments, the terminal device 101 may also be a terminal device other than a mobile phone, such as a tablet computer, a laptop computer, or a smartwatch.

[0080] Image forming device 102 is a device that can perform printing and document data processing functions, such as a printer or multifunction printer.

[0081] A data connection (e.g., USB wired data connection, Bluetooth wireless connection, WIFI wireless connection) can be established between the terminal device 101 and the image forming device 102 to achieve data interaction.

[0082] Storage device 103 (first storage device) is used to store data. A data connection can be established between storage device 103 and image forming device 102 to enable data interaction. Image forming device 102 can read data from storage device 103 and write data to storage device 103 based on the data connection. Image forming device 102 can be connected to one or more storage devices. Storage device 103 is one of the one or more storage devices connected to image forming device 102.

[0083] For example, storage device 103 can be a USB flash drive, which is inserted into image forming device 102 via a USB interface. Image forming device 102 accesses storage device 103 via the USB interface.

[0084] In one application scenario, terminal device 101 stores target data (e.g., file A), and terminal device 101 sends a file transfer operation instruction for the target file to image forming device 102. The file transfer operation instruction is used to instruct image forming device 102 to transfer the target data to storage device 103.

[0085] According to the method of the embodiments of this application, files in terminal device 101 can be transferred to storage device 103 without a PC, which improves the convenience of users transferring files.

[0086] Figure 2 as well as Figure 3This is a flowchart of a file transfer method according to an embodiment of this application.

[0087] Figure 1 The terminal device 101 shown executes Figure 2 The following process is shown to transfer the target data.

[0088] S201: Terminal device 101 generates a file transfer operation instruction for the target data.

[0089] In practice, S201 can be executed in a variety of different ways.

[0090] For example, in one implementation, the user selects target data stored on the terminal device 101 by clicking a button displayed on the screen of the terminal device 101, and confirms the transfer operation of the target data. The terminal device 101 triggers the execution of S201 based on the user's operation.

[0091] Furthermore, when the target data is transferred to the storage device 103, it is necessary to name the target data stored on the storage device 103. Therefore, it is necessary to instruct the image forming device 102 on the name to which the target data is stored on the storage device 103.

[0092] Specifically, in one implementation of S201, S201 includes S202.

[0093] S202: Terminal device 101 obtains the transfer name (first file name) for the target data. The transfer name of the target data is the file name used when the target data is saved to storage device 103.

[0094] In one embodiment, the filename of the target data on the terminal device 101 (e.g., file A) can be directly used as the transfer name of the target data.

[0095] In another embodiment, terminal device 101 may specify the transfer name of the target data (e.g., file B).

[0096] For example, the user enters the name of the target data to be transferred on the terminal device 101.

[0097] For example, terminal device 101 generates a transfer name for the target data based on preset naming rules. For example, it may directly use the file name of the target data; or it may generate a file name using the format: file name of the target data + date.

[0098] Furthermore, when transferring the target data to the storage device 103, it is necessary to specify the storage location of the target data on the storage device 103, that is, to specify the storage path of the target data on the storage device 103.

[0099] Specifically, in one implementation of S201, S201 includes S203.

[0100] S203: Terminal device 101 obtains the expected storage path (first storage path) of the target data on storage device 103.

[0101] For example, the user inputs the expected storage path of the target data on the storage device 103 on the terminal device 101.

[0102] Furthermore, in one embodiment, when the image forming apparatus 102 is connected to only one storage device (storage device 103), the image forming apparatus 102 transfers the target data to the storage device 103 when it receives a file transfer operation instruction for the target data.

[0103] In another embodiment, when the image forming apparatus 102 is connected to multiple storage devices including storage device 103, the terminal device 101 needs to specify which storage device the target data needs to be transferred to.

[0104] Specifically, in one implementation of S201, S201 includes S204.

[0105] S204: Terminal device 101 obtains device information (first device information) of storage device 103, the device information of storage device 103 includes the location information and / or device identifier of storage device 103.

[0106] Specifically, in one implementation, terminal device 101 obtains a device list from image forming device 102, which contains device information of all storage devices connected to image forming device 102.

[0107] Terminal device 101 displays a list of devices to the user. The user selects storage device 103 from the list of devices by clicking on the screen of terminal device 101.

[0108] In another implementation, the user inputs the device identifier of the storage device 103 on the terminal device 101.

[0109] In another implementation, the user enters the device name of the storage device 103 on the terminal device 101, and the terminal device 101 queries the corresponding device identifier based on the device name.

[0110] Furthermore, S201 also includes S204.

[0111] S205: Generate a file transfer operation instruction based on the target data's transfer name (first file name), the target data's desired save path (first save path), and the storage device 103's device information (first device information). Specifically, call the file transfer operation instruction template (the file transfer operation instruction template contains the basic structure of the instruction, but does not have specific instruction parameters), and add the target data's transfer name (first file name), the target data's desired save path (first save path), and the storage device 103's device information (first device information) to the blank file transfer operation instruction.

[0112] Furthermore, in one embodiment, the terminal device 101 may skip the execution of one or more steps in S202, S203, and S204. That is, the file transfer operation instruction may include any one or any combination of the following: the transfer name of the target data (first file name), the desired save path of the target data (first save path), and the device information of the storage device 103 (first device information).

[0113] For example, the image forming apparatus 102 has a pre-set default save name (first default name) for file transfer, such as the current date plus the number of times the file has been transferred within the day. In S201, the terminal device 101 does not execute S202. In S205, the finally generated file transfer operation instruction does not include the transfer name of the target data.

[0114] After receiving a file transfer operation instruction that does not contain a file name for the target data, the image forming apparatus 102 saves the target data on the storage device 103 according to a preset default name.

[0115] For example, the image forming apparatus 102 has a pre-set default save path (first default path) for file transfer, such as the root directory of the storage device 103. In S201, the terminal device 101 does not execute S203. In S205, the finally generated file transfer operation instruction does not include the desired save path (first save path) for the target data.

[0116] After receiving a file transfer operation instruction that does not contain a device identifier for a storage device, the image forming apparatus 102 saves the target data in a preset default save location.

[0117] For example, the image forming apparatus 102 may have a default save device pre-set for file transfer (e.g., a removable storage device inserted into the first USB port of the image forming apparatus 102 may be the default save device for file transfer). In S201, the terminal device 101 does not execute S204. In S205, the final generated file transfer operation instruction does not include device information of the storage device 103.

[0118] After receiving a file transfer operation instruction that does not contain a device identifier for a storage device, the image forming apparatus 102 determines the storage device 103 according to the preset default storage device.

[0119] S206: Terminal device 101 sends a file transfer operation instruction for the target data and the target data to image forming device 102.

[0120] In practice, in S201, various methods can be used to establish the correspondence between file transfer operation instructions and target data.

[0121] Specifically, in one implementation, in S201, the target data is packaged and added to the file transfer operation instruction. In S206, the file transfer operation instruction containing the target data is sent to the image forming apparatus 102. The target data contained in the file transfer operation instruction is the target data corresponding to the file transfer operation instruction.

[0122] In another implementation, the first data file following the file transfer operation command is pre-defined as the target data in the image forming apparatus 102. In S206, the file transfer operation command and the target data are sent sequentially to the image forming apparatus 102. The first file data received by the image forming apparatus 102 after receiving the file transfer operation command is the target data corresponding to that file transfer operation command.

[0123] In another implementation, in S201, description information of the target data is added to the file transfer operation instruction. In S206, the file transfer operation instruction containing the description information of the target data is sent to the image forming apparatus 102. After receiving the file transfer operation instruction, the image forming apparatus 102 determines the target data corresponding to the file transfer operation instruction from subsequently received data files based on the description information of the target data.

[0124] Figure 1 The image forming apparatus 102 shown performs the following operations. Figure 3 The following process is shown to transfer the target data.

[0125] S300 receives file transfer operation instructions and target data sent by terminal device 101.

[0126] The target data can be included in the file transfer operation instruction, or the target data and the file transfer operation instruction can be received as two separate data items. See S206.

[0127] S301, Identify storage device 103.

[0128] Specifically, when the file transfer operation instruction includes device information (first device information) of storage device 103, storage device 103 is determined from the storage devices connected to image forming apparatus 102 based on the device information (first device information) of storage device 103.

[0129] Alternatively, if the file transfer operation instruction does not contain device information (first device information) of storage device 103, the default save device is determined to be storage device 103. Refer to S201 and S205.

[0130] S302, Determine the transfer name of the target data (first file name).

[0131] Specifically, if the file transfer operation instruction contains the transfer name (first file name) of the target data, the transfer name (first file name) of the target data is extracted from the file transfer operation instruction.

[0132] or,

[0133] If the file transfer operation instruction does not include a transfer name (first file name) for the target data, the default save name (first default name) for the file transfer is used as the transfer name (first file name) for the target data. Refer to S201 and S205.

[0134] S303, determine the storage path (first storage path) of the target data on storage device 103.

[0135] Specifically, if the file transfer operation instruction includes the save path (first save path) of the target data, the save path (first save path) of the target data is extracted from the file transfer operation instruction.

[0136] or,

[0137] If the file transfer operation instruction does not include a save path (first save path) for the target data, the default save path (first default path) for the preset file transfer is used as the save path (first save path) on the storage device 103. Refer to S201 and S205.

[0138] S304, according to the save path (first save path) determined in S303, save the target data to the storage device 103, and save the data as the transfer name of the target data (first file name).

[0139] Furthermore, in one embodiment, the terminal device 101 generates a file transfer operation instruction based on the printer's print job instruction (PJL) format. Specifically, in one embodiment, the file transfer operation instruction uses the following format: UEL@PJL (file transfer operation instruction / print instruction start)

[0140] @PJL SET FILENAME = filename (the destination data will be saved as filename)

[0141] @PJL SET SAVETOUDISK = ON (Whether to save the target data to the storage device, ON means "yes") @PJLENTERLANGUAGE = BINARYFILE (The input language is binary language (BINARYFILE)) XXXXXXXXXX (Target data, where X represents the code of the target data)

[0142] UEL (End of file transfer / print command)

[0143] Figure 4 This is a flowchart of a file transfer method according to an embodiment of this application. After the image forming apparatus 102 receives the file transfer operation instruction in the format of the print job instruction (PJL), the image forming apparatus 102 executes the following... Figure 4 The following process is shown.

[0144] S400 receives file transfer operation commands (PJL).

[0145] S401, parsing PJL.

[0146] S402, check the SET SAVETOUDISK command and confirm SET SAVETOUDISK=ON.

[0147] S403, save the data (target data) after the ENTERLANGUAGE=BINARYFILE command to the root directory (default save path) of storage device 103 (the default save device), and save it as filename in PJL.

[0148] Furthermore, in another application scenario, the target data is not stored on the terminal device 101, but is stored on another device (a second storage device) other than the terminal device 101. For example, a server device.

[0149] For application scenarios where the target data is not stored on the terminal device 101, one implementation scheme for file transfer is that the terminal device 101 obtains the target data from the device storing the target data, and then... Figure 2 as well as Figure 3 The process shown implements file transfer.

[0150] Another implementation involves the terminal device 101 sending a file transfer operation instruction for the target file to the image forming apparatus 102. The file transfer operation instruction does not contain the target data, and the terminal device 101 does not send the target data after sending the file transfer operation instruction. The file transfer operation instruction instructs the image forming apparatus 102 to obtain the target data from the device storing the target data and transfer the target data to the storage device 103.

[0151] Taking the storage of target data on a cloud server device as an example, the image forming device 102 is connected to the cloud server device.

[0152] Figure 5 This is a flowchart of a file transfer method according to an embodiment of this application.

[0153] Figure 1 The terminal device 101 and the image forming device 102 shown perform... Figure 5 The following process is shown to transfer the target data.

[0154] S501, terminal device 101 sends a file transfer operation instruction to image forming device 102.

[0155] The file transfer operation instruction includes any one or a combination of any of the following: the transfer name of the target data (first file name), the desired save path of the target data (first save path), and the device information of the storage device 103 (first device information). Refer to S201 and S205.

[0156] Furthermore, the file transfer operation instruction also includes the storage location information of the target data, which is used to indicate the save location of the target data (e.g., which device it is saved on, which file path on the device it is saved in, and which file name it is saved with on the device).

[0157] For example, in one embodiment, the storage location information of the target data includes any one or a combination of the following:

[0158] The name by which the target data is saved on the second storage device (second file name);

[0159] The location (second storage path) where the target data is stored on the second storage device;

[0160] Location information and / or device identifier (second device information) of the second storage device.

[0161] S502, the image forming apparatus 102 determines the storage device (cloud server device) (second storage device) for the target data.

[0162] Specifically, when the file transfer operation instruction includes second device information, the second storage device is determined based on the second device information.

[0163] Alternatively, if the file transfer operation instruction does not include information about the second device, the preset default device can be used as the second storage device.

[0164] S503, the image forming apparatus 102 sends a data acquisition request to the cloud server device (second storage device), the data acquisition request being used to request the acquisition of target data.

[0165] Specifically, in one implementation of S503, when the file transfer operation instruction includes a second file name, a data acquisition request containing the second file name is sent to the second storage device, and the second file name is the name by which the target data is saved on the second storage device.

[0166] or,

[0167] If the file transfer operation instruction does not include a second file name, a data retrieval request containing a preset second default name will be sent to the second storage device. The preset second default name is the name at which the target data is saved on the second storage device.

[0168] In another implementation of S503, when the file transfer operation instruction includes a second save path, the data acquisition request containing the second save path is sent to the second storage device, where the second save path is the save path of the target data on the second storage device.

[0169] or,

[0170] If the file transfer operation instruction does not include a second save path, the data acquisition request containing a preset second default path is sent to the second storage device, where the preset second default path is the save path of the target data on the second storage device.

[0171] The S505 cloud server device locates the corresponding file and retrieves the target data based on the data retrieval request.

[0172] S506, the cloud server device sends target data to the image forming device 102.

[0173] S507, the image forming apparatus 102 receives target data.

[0174] In step S508, the image forming apparatus 102 saves the target data to the storage device 103 according to the file transfer operation instruction. See steps S301-S303.

[0175] Furthermore, in practical application scenarios, when a user wants to print target data in terminal device 101, one solution is to use the preview program of terminal device 101 to preview the data on terminal device 101, and then terminal device 101 generates a rasterized halftone image based on the preview image for printing (GDI printing). However, due to the limitations of the preview image quality, GDI printing cannot achieve high-quality printing.

[0176] To address the aforementioned issues, one embodiment of this application proposes a printing method. Specifically, based on the file transfer method of this embodiment, the target data in the terminal device 101 is first transferred to the storage device 103 via the image forming device 102, and then the image forming device 102 directly prints the target data stored on the storage device 103.

[0177] Specifically, in one implementation of the printing method, after the terminal device 101 sends a file transfer operation instruction to the image forming device 102, it sends a print instruction to the image forming device 102. The print instruction is used to instruct the image forming device 102 to print the target data stored on the storage device 103.

[0178] In another implementation of the printing method, terminal device 101 adds a print command to a file transfer operation instruction and sends the file transfer operation instruction containing the print command to image forming device 102. For example, in one embodiment, terminal device 101 generates the file transfer operation instruction based on the printer's print job instruction (PJL) format. Specifically, in one embodiment, the file transfer operation instruction uses the following format:

[0179] UEL@PJL (File transfer operation command / print command start)

[0180] @PJL SET FILENAME = filename (the destination data will be saved as filename)

[0181] @PJL SET SAVETOUDISK = ON (Whether to save the target data to the storage device, ON means "yes") @PJL SET PRINTUDISKFILE = ON (Whether to print the target data on the storage device, ON means "yes") @PJLENTERLANGUAGE = BINARYFILE (The input language is binary language (BINARYFILE)) XXXXXXXXXX (Target data, where X represents the code of the target data)

[0182] UEL (End of file transfer / print command)

[0183] Figure 6This is a flowchart of a file transfer method according to an embodiment of this application. After the image forming apparatus 102 receives the file transfer operation instruction in the format of the print job instruction (PJL), the image forming apparatus 102 executes the following... Figure 6 The following process is shown.

[0184] S601 receives file transfer operation instructions (PJL).

[0185] S602, parsing PJL.

[0186] S603, check the SET SAVETOUDISK command and confirm SET SAVETOUDISK=ON.

[0187] S604, check the SET PRINTTOUDISK command.

[0188] S605, save the data (target data) after the ENTERLANGUAGE=BINARYFILE command to the preset default save location (storage device 103), and save it as filename in PJL.

[0189] S606 checks if the PRINTTOUDISK instruction is ON.

[0190] If the PRINTTOUDISK instruction is not ON, it is determined that the PRINTTOUDISK instruction will not be executed, and the operation ends.

[0191] If the PRINTTOUDISK instruction is ON, execute S608.

[0192] S608 loads target data from storage device 103, sends the target data to the Procedure Design Language (PDL) module for parsing, and the PDL module generates halftone pages.

[0193] S609, Print the halftone page generated by the PDL module.

[0194] After S609, this operation is complete.

[0195] According to the method in this application embodiment, when a user wants to print target data from terminal device 101, image forming device 102 loads the target data from storage device 103 and prints it directly. This not only protects the user's privacy but also ensures print quality. Compared to printing via app preview, it achieves better printing results.

[0196] Furthermore, one embodiment of this application also proposes a method for uploading files to a terminal device 101, thereby uploading files from storage device 103 to the terminal device 101.

[0197] Figure 7 This is a flowchart of a file upload method according to an embodiment of this application.

[0198] Terminal device 101 and image forming device 102 perform as follows Figure 7 The following process is shown.

[0199] S701, terminal device 101 sends a request file list instruction to image forming device 102. The request file list instruction is used to request to view file information in storage device 103.

[0200] Specifically, in one embodiment, terminal device 101 generates a request file list instruction based on the printer's print job instruction (PJL) format. Specifically, in one embodiment, the request file list instruction uses the following format:

[0201] UEL@PJL

[0202] @pjl set requestlistudisk = yes(whether to upload file list, yes means "yes")

[0203] UEL

[0204] In other embodiments, terminal device 101 may also request a file list from image forming device 102 based on other server-client protocols.

[0206] S703, the image forming apparatus 102 obtains a file list from the storage device 103, the file list containing the file names of the files stored on the storage device 103.

[0207] S704, the image forming apparatus 102 sends the file list of the storage device 103 to the terminal device 101.

[0208] S705, Terminal device 101 receives file list from storage device 103.

[0209] S706, terminal device 101 outputs a list of files on storage device 103 to the user.

[0210] Specifically, terminal device 101 displays a list of files from storage device 103 on the screen. The user can select one or more file names from the file list by clicking.

[0211] S707, Terminal device 101 determines one or more file names selected by the user based on user input.

[0212] S708, terminal device 101 sends a request to upload a file to image forming device 102.

[0213] The request to upload a file instruction includes one or more file names selected by the user. The request to upload a file is used to instruct the image forming device 102 to upload the file corresponding to the file name to the terminal device 101.

[0214] Specifically, in one embodiment, terminal device 101 generates a request to upload a file instruction based on the printer's print job instruction (PJL) format. Specifically, in one embodiment, the request to upload a file instruction uses the following format:

[0215] UEL@PJL

[0216] @PJL SET UPLOADUDISKFILENAME = filename (indicates the file to be uploaded, where filename is the filename selected by the user).

[0217] @PJL SET STARTUPLOADUDISKFILE=ON(Whether to upload files, ON means "yes")

[0218] UEL

[0219] S709, the image forming apparatus 102 receives a request to upload.

[0220] S710, the image forming apparatus 102 uploads the file corresponding to the file name in the upload file instruction to the terminal device 101 according to the request upload instruction.

[0221] Specifically, in S710, the image forming device 102 can upload files to the terminal device 101 using a similar PJL format protocol or other existing file transfer protocols, or a custom server-client protocol.
