[0044] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, a person of ordinary skill in the art can understand that in each embodiment of the present invention, many technical details are proposed for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed by the claims of this application can be realized.
[0045] The first embodiment of the present invention relates to a printing method, such as figure 1 , Including the following steps:
[0046] Step 101: Receive a communication connection establishment request from a mobile terminal.
[0047] Specifically, the printer side receives the communication connection request from the mobile terminal; among them, the communication connection can be an NFC connection or an RFID connection. In this embodiment, the NFC connection is taken as an example, that is, in this embodiment, the printer side receives NFC connection request from the mobile terminal. The mobile terminal initiates a connection request and starts the entire process, which realizes the convenience of opening the user's self-service printing service, while ensuring the smooth execution of subsequent operation steps.
[0048] It should be noted that the mobile terminal in this embodiment may be a mobile phone. Since existing mobile phones are already very popular, using a mobile phone as a mobile terminal can also improve the user's convenience in using the printing method in this embodiment. More specifically, the SIM card that can be used by the mobile phone in this embodiment is an NFC-SIM card. The NFC-SIM card is a dual-function SIM card that has all the functions of a normal SIM card and supports the NFC payment function.
[0049] It is worth mentioning that Near Field Communication (NFC), also known as Near Field Communication, is a short-distance high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices (in Within ten centimeters) exchange data. NFC has the characteristics of short distance, high bandwidth, low energy consumption, low cost, easy to use and more intuitive. This technology is mainly used to provide M2M (Machine to Machine) communication in handheld devices such as mobile phones. Due to the natural security of near field communication, the use of NFC technology to pay for expenses is safe and reliable, and has good development prospects. In practical applications, NFC chips can be used. NFC chips have the function of mutual communication, and have computing capabilities, and also contain encryption logic circuits. In addition, NFC is a short-distance connection protocol that provides easy, safe, fast and automatic communication between various devices.
[0050] The mobile phone in this embodiment has a built-in NFC chip. NFC technology adds the function of two-way data transmission, making it more suitable for electronic money payment; and mutual authentication and dynamic encryption and one-time key (OTP) can be implemented on NFC . With a mobile phone with a built-in NFC chip, people can connect with the services and transactions they hope to receive at any place, any time, and through any device, so as to complete payments and obtain information.
[0051] It should be noted that the technical principle of NFC is as follows: NFC-enabled devices can exchange data in active or passive mode. In the passive mode, the device that initiates the NFC communication, also known as the NFC initiating device (master device), provides a radio frequency field (RF-field) during the entire communication process. It can select a transmission speed of 106kbps, 212kbps or 424kbps to send data to another device. The other device is called the NFC target device (slave device), which does not need to generate a radio frequency field, but uses load modulation technology, which can transmit data back to the initiator device at the same speed. This communication mechanism is compatible with contactless smart cards based on ISO14443A, MIFARE and FeliCa. Therefore, in passive mode, the NFC initiator can use the same connection and initialization process to detect and establish contact with the contactless smart card or NFC target device .
[0052] Step 102: Receive a print request from a mobile terminal.
[0053] Specifically, it is the printer that receives the print request from the mobile terminal. Among them, the print request may include the number of sheets, size, number of copies, etc. that the user needs to print.
[0054] Step 103: Calculate the printing fee according to the printing request.
[0055] Specifically, the printer calculates the printing cost based on the number of sheets, size, and number of copies that the user needs to print.
[0056] Step 104: Send a payment request instruction to the mobile terminal.
[0057] In other words, the printer can notify the mobile phone to pay after calculating the printing cost.
[0058] Step 105: After confirming that the printing fee paid from the mobile terminal is correct, send a file transmission instruction to the mobile terminal.
[0059] In other words, the printing fee paid by the mobile terminal is approved, and after approval, the mobile phone is notified to send the document to be printed.
[0060] Step 106: Receive the file to be printed from the mobile terminal.
[0061] Specifically, the method of receiving the file to be printed is Bluetooth transmission and reception. Use Bluetooth's low power consumption and high transmission speed to speed up the transmission speed of files to be printed.
[0062] Step 107: Start the printer to print the received file.
[0063] Step 108, delete the printed file.
[0064] Specifically, deleting files after printing can increase the security of user information. It should also be noted that the printed file is both the file received in step 107 and the file to be printed in step 106.
[0065] Compared with the prior art, the main difference and effect of this embodiment is: the communication interaction between the printer and the mobile terminal is used to realize the self-printing service on the printer. Among them, the NFC payment or RFID payment is used to realize the user's printing service. In the whole process of experiencing the printing service, you can realize the full self-service printing service for users without the assistance of management personnel. In addition to self-service payment, it also includes self-service transfer of files to be printed and automatic printing of the control printer. The printer can print the user's personal files. The embodiment of the present invention provides the user with a self-service and convenient paid printing service, which increases the convenience of the self-service printing service and improves the user experience. In this embodiment, the payment function of NFC and the data exchange and transmission functions in Bluetooth communication are used, and the printer with NFC and Bluetooth functions is used to improve public services. In practical applications, the NFC chip or module is used for mobile payment. The Bluetooth link between the two is used for data exchange and collection.
[0066] It is worth mentioning that in practical applications, you can use such figure 2 The illustrated schematic diagram of the structure of the printer end implements the printer end in the printing method in this embodiment.
[0067] In addition, you can also use image 3 The shown schematic structural diagram of the mobile terminal implements the mobile terminal in the printing method in this embodiment.
[0068] In addition, the printer manufacturer can jointly design a new type of NFC Bluetooth toll printer with the existing printer, or design and produce the device on the printer side separately, so that there is no need to eliminate the existing ordinary printers, only the device and the existing The printing method in this embodiment can be realized by connecting an ordinary printer. Connecting a corresponding device to the printer that needs to apply this function can not only reduce the update cost of the printer, but also facilitate promotion.
[0069] The second embodiment of the present invention also relates to a printing method. This embodiment is roughly the same as the first embodiment. The main difference is: the first embodiment is that the printer deletes the printed files after the printer finishes printing. In the method, the printer sends a printing completion instruction to the mobile terminal after the printer finishes printing, and deletes the printed file after receiving the delete instruction from the mobile terminal. This not only enables users to further understand the progress of printing and clarify whether the file has been printed, but also can control whether to delete the file according to the user's wishes, increase the user's autonomous control, and further improve the user experience.
[0070] The flow chart of the printing method in this embodiment is as follows Figure 4 As shown, the details are as follows:
[0071] Steps 401 to 407 are similar to steps 101 to 107 in the first embodiment, and will not be repeated here.
[0072] Step 408: Send a printing completion instruction to the mobile terminal.
[0073] Specifically, after the printer finishes printing, the printer sends a printing completion instruction to the mobile terminal.
[0074] Step 409: After receiving the delete instruction from the mobile terminal, delete the printed file.
[0075] In other words, the printer does not automatically delete the printed file by default, but only deletes it after receiving the delete instruction. In this way, the user can judge the importance of the print file by himself, and the user experience can be improved.
[0076] The division of the steps of the various methods above is only for clarity of description. When implemented, it can be combined into one step or some steps can be split into multiple steps, as long as they contain the same logical relationship, they are all within the scope of protection of this patent. ; Adding insignificant modifications to the algorithm or process or introducing insignificant design, but not changing the core design of the algorithm and process are within the scope of protection of the patent.
