In the above-described operating environment, the present application provides a cloud printing method as shown in fig. 3. Fig. 3 is a flowchart of a cloud printing method according to a first embodiment of the present invention.

Step S302, a file to be printed sent by a cloud printing program is received.

In the above step S302 of the present application, the file to be printed may be a file encrypted by the cloud print program according to the obtained password. The password may include at least one of: the password input by the user and the password automatically generated by the system. The cloud print program may be a print driver installed on a terminal (e.g., PC, cell phone, tablet).

The user opens the document software and selects the printing function, a printer with 'cloud printing' can be seen in the printing interface, and the cloud printing command can be triggered to be generated by selecting 'cloud printing' and clicking a printing button. After receiving the cloud print instruction, the cloud print program converts the document to be printed into a specific printable format document, for example, into a format such as PCL (Printer Control Language ), postScript (a programming language), and the like, and outputs and saves the document in a file.

The user may input a password for document encryption or automatically generate an encryption key in combination with the system and encrypt the document with the generated key to generate the file to be printed as described above. It should be noted that the file to be printed cannot be decrypted at the cloud end (also referred to as a cloud server). The encryption algorithm may use symmetric encryption, such as DES (Data Encryption Standard ), among others.

Furthermore, the cloud printing program is connected with cloud printing service of the cloud, and the file to be printed is transmitted to a cloud server (which may include a cloud printing server). Meanwhile, some auxiliary information such as user information or terminal information can be transmitted together and stored on the cloud server.

Step S304, according to the print request, the file to be printed is sent to a target printer corresponding to the print request.

In the above step S304, the target printer decrypts the file to be printed according to the password and prints the file. The above-mentioned print request may be sent by a target printer, for example, the user opens the target printer on the printer to be printed (i.e. the above-mentioned target printer), browses the cloud print file list, selects the corresponding file, triggers to generate the print request, and after obtaining the file to be printed, inputs a password (the password may be a password set by the user and/or a password generated by the system) and prints the password; the print request may be a client installed on a mobile phone (e.g.

Skype For

Microsoft />

Etc.), for example, if the target printer has no input mode, the client may browse the cloud print file list by scanning the identifier (e.g., two-dimensional code) of the printer, select the corresponding file, trigger to generate the print request, and after acquiring the file to be printed, input a password (the password may be a password set by the user and/or a password generated by the system), and then send the password for decryption to the target printer.

According to the embodiment, the encrypted file to be printed is uploaded to the cloud server, and the cloud server issues the file to be printed to the appointed target printer for printing, so that the purpose that the printer can be selected nearby for printing according to the requirement is achieved, the technical effects of improving the printing operation convenience and safety are achieved, and the technical problem of inconvenience in operation caused by the fact that the related technology can only select the fixed printer for printing is solved.

Optionally, before the file to be printed is sent to the target printer corresponding to the print request according to the print request, the cloud printing method of this embodiment may further include: receiving a file list request sent by a client; returning a file list corresponding to the file list request to the client, and determining a file to be printed by the client based on the file list; and receiving a printing request returned by the client, wherein the printing request comprises the equipment ID of the target printer and a file list for indicating the file to be printed, and the equipment ID is obtained by the client through scanning the identification of the target printer.

Specifically, the client scans the identifier (for example, two-dimensional code) of the target printer, obtains the device ID of the target printer, then obtains a file list (i.e., the above-mentioned print file list) from the cloud server, the user checks the file to be printed in the file list through the client, the client generates a print request (the print request includes the device ID of the target printer and the file list for indicating the file to be printed), and sends the print request to the cloud server, browses the cloud print file list, selects a corresponding file, triggers the generation of the print request, and after obtaining the file to be printed, inputs a password (the password may be a password set by the user and/or a password generated by the system), and then sends the password for decryption to the target printer.

Optionally, before sending the file to be printed to the target printer corresponding to the print request, the cloud printing method of this embodiment may further include:

step S10, authority authentication is carried out on the file to be printed according to the printing request.

In the above step S10 of the present application, the authority authentication is used to determine at least one of the following: the account login state of the client and the relation between the login account and the file to be printed. After receiving the print request, the cloud server may perform a file security (authority) check on the file to be printed, and specifically, the cloud server may check the login state of the user and the relationship between the user and the file (the user can only operate the file submitted by himself).

Step S12, if the authority authentication is passed, binding relation authentication is performed on the target printer.

In the above step S12 of the present application, the binding relationship authentication is used to determine the correspondence relationship between the target printer and the control unit (in this embodiment, the control unit may be a print cartridge). Under the condition that authority authentication is passed, the cloud server can check the binding relationship of the printer/box for the target printer, specifically, the relationship between the printing box and the printer can be 1:n, so that the cloud server needs to check the binding relationship corresponding to the printing box and the target printer. The user controls the target printer, finds out the corresponding printing box through the binding relation of the target printer, and then issues the corresponding printing information to the printing box through the long connecting channel of the printing box.

It should be noted that the print box and the printer may be in the same local area network and connected by wired or wireless means; the print cartridge and the printer may also be in different local area networks, and connected by a transmission device (e.g., a network adapter, a router), which is within the scope of the present embodiment.

Optionally, sending the file to be printed to the target printer corresponding to the print request may include:

step S20, a print instruction is sent to the control unit.

In the above step S20 of the present application, the print instruction includes an equipment ID and a URL of a file to be printed, where the URL includes user information, and the control unit (print box) obtains the URL from the print instruction, and signs the URL by using a pre-stored key, so as to obtain the URL carrying the sign information.

Optionally, the following related data information may be included in the print instruction: deviceName (unique device ID of printer) of the printer, URL. User information is attached to the URL, and specific format examples are as follows:

https://down.dingtalk.com/media/lBDPBY0V4v6-1qLOZUwvK84mTTfd.pdfuid＝xxxx

after receiving the printing instruction, the printing box acquires the URL from the printing instruction, and signs the URL by using the SecretKey (namely the prestored key), specifically, the printing box is internally provided with a globally unique SecretKey (the SecretKey cloud server is also stored during production of a production line, and meanwhile, the SecretKey can dynamically generate a pair of public and private keys and implant the private keys into the equipment during activation of later equipment), so that relevant information of the URL is signed, the signed information is superimposed into the URL, and the URL carrying the signed information is downloaded during downloading.

Alternatively, the signing algorithm of the present embodiment is exemplified as follows:

SignString=BASE 64 (MD 5 (DeviceName+secret+PK+TIME+URL)), where DeviceName may be the device ID of the print cartridge and/or the device ID of the printer.

Examples of signed URLs are as follows:

https://down.dingtalk.com/media/lBDPBY0V4v6-1qLOZUwvK84mTTfs.pdfuid＝xxxx&sign＝SignString&time＝TIME

step S22, receiving the URL carrying the signing information sent by the control unit.

Step S24, checking the URL carrying the signed information.

In the above steps S22 to S24, after receiving the URL carrying the signing information, the cloud server may verify the URL carrying the signing information. Optionally, verifying the URL carrying the signing information includes: acquiring signing information and user information from the URL carrying the signing information; and checking the signed information and the user information.

Wherein, check the tagged information: after the cloud server obtains the URL requested to be downloaded, the information of the signed part is extracted, verification is carried out, and after the verification is passed, user information verification is carried out; checking user information: and checking corresponding user information in the URL.

Step S26, in the case that the verification is passed, the file to be printed is sent to the target printer through the control unit.

Optionally, in the case of verification passing, the method further comprises: detecting first enterprise information corresponding to a file to be printed and second enterprise information corresponding to a control unit (printing box); and if the first enterprise information is the same as the second enterprise information, triggering and executing the transmission of the file to be printed to the target printer through the control unit (printing box).

Specifically, the relationship between the file and the box-bound enterprise is checked: and checking the enterprise information of the file owner and the enterprise information of the box binder, returning to download the file if the file owner and the box binder are consistent, otherwise, interrupting the downloading. The enterprise information of the file owner means that the enterprise needs to register an enterprise account number on a platform and fill in the corresponding enterprise information; the enterprise information of the box binder refers to the enterprise to which the print box is bound, and the enterprise is registered on the platform.

Next, a cloud printing method of the present embodiment will be described with reference to fig. 4 (a):

step a, selecting a print document.

In the step a, the user selects the print document through the document software, wherein the document software is installed on the terminal and refers to any software which needs to output the print document.

And step b, transmitting the printed document.

In the step b, the document software sends the print document to the cloud print program after selecting the print document, wherein the cloud print program is a print driver installed on the PC and can be installed in advance by the user.

And c, processing the document format.

In the step c, after the cloud printing program receives the print document, the format processing is performed on the document, that is, the document to be printed is converted into a specific printable format document, for example, into a format such as PCL, postScript, and the document is output and stored in the file.

And d, inputting a password by a user.

In the above step d of the present application, the user may input a password for encrypting the document, or automatically generate an encryption key (such as a company domain account, a client account, etc.) in combination with other account systems of the company.

And e, generating an encrypted document.

In the above step e of the present application, the cloud print program encrypts the document with the generated key. The document cannot be decrypted at the cloud end, and the encryption algorithm can use symmetric encryption, such as DES.

And f, uploading the encrypted document and the printing related information.

In the step f, the cloud printing program is connected with the cloud printing service of the cloud, and the encrypted document is transmitted to the cloud printing server. At the same time, some ancillary information, such as user or PC information, is also transmitted and saved to the cloud print server. The cloud printing service refers to a cloud printing service, and provides storage, queue maintenance and the like of printing documents.

Step g, storing the encrypted document.

In the step g, the cloud printing service stores the encrypted document, and returns a result to the cloud printing program, so that the cloud printing program feeds back the completion of the cloud printing to the document software.

And h, starting printing by a user.

In the step h, the user opens the target printer on the target printer to be printed, browses the cloud print file list, and selects the corresponding file.

Step i, the user inputs a password.

In the above step i, after selecting the file, a password is input (if a company or other account system is combined, a decryption key is automatically generated by the account system).

Step j, obtaining the encrypted document.

In the step j, the target printer obtains the encrypted document from the cloud print service according to the selection of the user.

And step k, decrypting the document.

In the above step k, the target printer decrypts the encrypted document according to the password in step i after obtaining the encrypted document.

Step l, printing the document.

According to the cloud printing method of the embodiment, no matter how many printers are deployed, the printing driver is only required to be installed once. Because the cloud printing program is a virtual printing driver, the printing operation is not really performed when the user selects printing, but the document is simply transferred into a printed document format and is transferred to the cloud. And then, the cloud end issues the print file to a specific selected printer. Further, the user can select the printer nearby according to his/her own position. Because the file to be printed is in the cloud, the user downloads the print file from the cloud for printing after nearby printer selection. The document to be printed stored in the cloud is encrypted and stored by using the private key of the user, so that the document is intercepted in the cloud or other people and cannot be decrypted, and the security of the cloud printed document is ensured.

Next, a cloud printing method of the present embodiment will be described with reference to fig. 4 (b):

and step A, starting the printing of the document.

In the above step a of the present application, the user selects the print document through the document software, wherein the document software installed on the terminal refers to any software that needs to output the print document. After selecting the print document, the document software sends the print document to a cloud print program, which refers to a print driver installed on a PC, which can be installed in advance by the user.

And step B, converting the document format by the cloud printing program.

In the step B, after the cloud print program receives the print document, the format processing is performed on the document, that is, the document to be printed is converted into a specific printable format document, for example, into a format such as PCL, postScript, and the document is output and stored in the file.

And C, waking up the client.

And D, uploading the document to a file server.

In the above steps C to D, after the document is formatted, the client may be opened, the document is uploaded to the file server by the client, and the file server returns an uploading result after the uploading is successful.

In this process, the document may be encrypted, which will not be described here.

And E, scanning the two-dimensional code of the target printer.

Step F, acquiring the URL (SN of the target printer).

In the above steps E to F, the user selects the target printer, and scans the two-dimensional code of the target printer through the client to obtain the URL (SN of the target printer).

And G, acquiring a file list from the file server.

And step H, checking the print file.

And step I, submitting a print file list (SN, file list).

In the steps G to I, after the client scans the two-dimensional code of the target printer to obtain the URL (SN of the target printer), the client obtains the file list from the file server, the user selects the print file from the file list through the client, and the client submits the print file list (the print file list includes SN and the file list of the selected print file) to the file server.

And step J, checking file security (authority).

In the above step J of the present application, the file server will check the login status of the user and the relationship between the user and the file, i.e. the user can only operate the file submitted by himself.

Step K, sending the printing instruction to the IoT cloud.

In the above step K of the present application, the print instruction includes URL, PK of the target printer, DN.

And step L, checking the binding relation between the printer and the box.

In the above step L of the present application, the relationship between the box and the printer is 1:n, so the IoT cloud needs to check its corresponding binding relationship. The user guides the corresponding printer, and finds the corresponding printing box through the binding relation of the printer. And issuing the corresponding printing information to the printing box through the long connecting channel of the printing box.

And step M, sending the printing instruction to a printing box.

In the above step M of the present application, the printing instruction includes the following related data information: deviceName (unique device ID of printer) of printer, file URL. User information is attached to the URL, and specific format examples are as follows:

https://down.dingtalk.com/media/lBDPBY0V4v6-1qLOZUwvK84mTTfd.pdfuid＝xxxx

and step N, acquiring a file URL and signing by using the SecretKey of the printing box.
