Detailed ways

In order to make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the application, and are not used to limit the application.

Example one

Computer virtualization technology mainly includes server virtualization, application virtualization, and desktop virtualization. At present, technologies such as network virtualization and graphics card virtualization are developing rapidly, and physical devices will all support virtualization technology to realize IAAS (Infrastructure as a Service) and realize true cloud computing.

Desktop virtualization technology is currently the fastest growing and most promising technology. Desktop virtualization technology (Desktop virtualization, or Virtual Desktop Infrastructure) is a server-based computing model, which borrows the traditional thin client model, and can host and manage all desktop virtual machines in the data center. At the same time, users You can get a complete PC experience. Simply put, desktop virtualization is a technology that supports enterprise-level remote dynamic access to desktop systems and unified hosting of data centers, allowing users to access cloud desktop systems on the network through any device, at any place, and at any time.

After the enterprise deploys the cloud desktop platform uniformly, the enterprise office organization can remotely use the cloud desktop platform for cloud desktop office through the Internet or private network. The local printer of the enterprise organization can be connected to the thin client, and the general solution of the cloud desktop peripherals, such as redirection technology , Redirect the printer connected to the thin client to the cloud desktop side, so that users can use the printer on the cloud desktop. Please refer to FIG. 1 showing a schematic diagram of the use of the printer.

In FIG. 1, the first printer 11 may be any one of a USB interface, a serial port or a parallel port printer, which is connected to the thin client 12 (the connection relationship between the two is shown by a solid line in FIG. 1), The thin client 12 corresponds to the cloud desktop 13 on the cloud platform side, and there is a communication connection between the two. A PC 14 and a second printer 15 also exist in the network where the thin client 12 is located.

The first printer 11 can be redirected to the cloud desktop 13 side through the redirection technology, so that users of the cloud desktop 13, that is, users who work on the cloud desktop 13 through the thin client 12 can use the first printer 11. However, because the first printer 11 is redirected to the cloud desktop 13 side, the PC 14 can no longer use the first printer 11.

The second printer 15 can be a network printer, and the PC 14 on the same network as the second printer 15 can use the printer, but since the network printer 15 is not redirected to the cloud desktop 13 side, it is not on the same network as the cloud desktop 13, Therefore, the user of the cloud desktop 13 cannot use the second printer 15.

In order to solve the problem that in the related cloud desktop printing solution, in order to allow the cloud desktop to use the client side printer, the printer is redirected to the cloud desktop side, which causes the client side ordinary PC to be unable to use the printer, and the cloud desktop cannot use the client side network printer. This embodiment provides a method for using a printer, please refer to the flowchart of the method for using the printer shown in FIG. 2.

S202: The printer agent searches for printers in the local network.

In this embodiment, the printer agent is deployed on the client side, which has a one-to-one correspondence with the virtual printers deployed in the cloud desktop, and can communicate with each other. The printer agent can search for printers in its local network and collect information about the printers it can access. In some examples of this embodiment, the process of the printer agent searching for printers can be to search for the search results after logging in to the cloud desktop, or to log in to the cloud desktop after searching for the search results, or even in the process of searching for the printer. Search while logging in.

It should be noted that the printer in this embodiment may be a device that only supports a printing function, or a device that supports functions including a printing function but also supports functions such as copying and scanning. The type of printer is not strictly limited in this embodiment. The printers searched by the printer agent may include USB port printers, serial port printers, and parallel port printers, and may also include network printers, shared printers, and so on.

S204: The printer agent reports the printer search result to the virtual printer in the cloud desktop.

After the printer proxy search is completed, report the printer search results to the virtual printer. The virtual printer is deployed in the cloud desktop because the physical printer is not on the cloud desktop side. Therefore, the virtual printer on the cloud desktop is actually similar to an "application". The printer search results may include identification information of each printer (for example, the name of the printer or the hardware identification, etc.) that the printer agent has searched in the local network. In some examples of this embodiment, the printer search results may further include the deployment locations of the searched printers. In other examples, the printer search results may include the type of each printer, for example, identifying whether each printer belongs to a local printer connected to a printer agent, a network printer, or a shared printer. In some examples of this embodiment, the printer search results may also include the brand and model of each printer. There is no doubt that the information contained in the printer search results can also be one or a combination of the above.

S206: The virtual printer generates a job task based on the job requirement and the printer search result.

After the virtual printer receives the printer search results reported by the printer agent, it can learn which printers are on the printer agent side. Therefore, when the cloud desktop user has job requirements, the virtual printer can be based on the user's job requirements and the printer reported by the printer agent The search results generate job tasks. It is understandable that the job requirements mentioned here may include at least one of printing requirements, copying requirements, and scanning requirements. Correspondingly, the job tasks also include at least one of printing tasks, copying tasks, and scanning tasks. In some examples of this embodiment, the user will also indicate the details of the requirement in the job requirement. For example, assuming that the user’s current job task is a printing task, it will not only indicate to the virtual printer that the requirement is a printing requirement, but also instruct printing. The object, the number of copies to be printed, the printing method (such as whether to print on both sides, and the way to turn pages when printing on both sides), etc.

In some examples of this embodiment, after the virtual printer receives the job request issued by the user, it can automatically select a job executor for the user's current job task based on the printer information it knows from the printer search results In this solution, the user of the cloud desktop does not need to know the situation of the printer on the agent side, and the virtual printer does not need to present the printer information in the printer search result to the user.

However, it is understandable that if there is only one printer on the printer agent side or the number of printers is small, and the distance between them is not very far, the virtual printer automatically selects the task performer for the user's job requirements, and the task performer executes the job After the task, the user can easily find out which printer is used to complete the task. However, if there are a lot of printers on the printer agent side, or they are far away from each other, when the virtual printer automatically selects the task performer, the user does not know which printer is helping him to achieve the job task. Therefore, it is very important for the user. inconvenient. In some examples of this embodiment, the virtual printer can inform the cloud desktop user of the task performer after the task performer is selected, so that the user can know which printer is currently helping him achieve his job requirements. In some examples, users can also learn where the printer is deployed, and even the brand model.

In some other examples of this embodiment, after the virtual printer receives the printer search result reported by the printer agent side, it can present the printer information in the printer search result to the user. For example, in some examples of this embodiment, after the user starts the virtual printer from the cloud desktop, the virtual printer can display the printer information in the printer search results, so that the user can understand the printer information, and then choose the most convenient one. The printer performs job tasks. Therefore, in these examples, the user will not only issue his printing requirements to the virtual printer, but also indicate the task performer he has selected to the virtual printer.

S208: The virtual printer issues the job task to the printer agent.

After the virtual printer generates a job task based on the user's job requirements and printer search results, it can deliver the job task to the printer agent. In this embodiment, because the virtual printer is deployed in the cloud desktop, the interaction between the virtual printer and the printer agent is actually the interaction between the cloud desktop and the printer agent, and the information interaction between the two can be based on the remote desktop transfer protocol achieve.

S210: The printer agent selects the task performer from the local network and instructs the instructed printer to perform the job task.

After the printer agent receives the job task issued by the virtual printer, it can obtain the task performer's instruction from the job task. The task performer's instruction is used to instruct the printer to perform the job task. Therefore, the printer agent can get from the local network Select the task performer to instruct the corresponding printer to perform the job task.

In this embodiment, a virtual printer is deployed on the cloud desktop side and a printer proxy is set on the client side to form a cloud desktop printing system. Please refer to a schematic diagram of the cloud desktop printing system shown in Figure 3: the cloud desktop printing system 3 includes The virtual printer 31 and the printer agent 32. The virtual printer 31 receives the printer search results reported by the printer agent 32, understands the printer deployment situation on the client side based on the printer search results, and then generates and issues job tasks according to the job requirements of the cloud desktop user; The agent 32 searches the printer information on the client side and reports it to the virtual printer 31 on the cloud desktop side, and receives the job task issued by the cloud desktop side. The printer job task is realized in the case of being directed to the cloud desktop side. This not only does not need to redirect the local printer on the client side to the cloud desktop side, but also allows ordinary terminal devices on the client side to use local printers. At the same time, the cloud desktop side You can also use network printers on the client side. The cloud-based desktop printing system 3 can expand the usage scenarios of printers, improve printer utilization, optimize resource allocation, and reduce system costs.

In some other examples of this embodiment, the cloud desktop printing system may also include a management platform, and the management platform may manage virtual printers on each cloud desktop. Therefore, in some examples of this embodiment, referring to FIG. 4, the cloud desktop printing system 4 includes a management platform 40, N virtual printers 41, and N printer agents 42, and N is greater than or equal to 2. The virtual printer 41 and the printer agent 42 form a pair, and each pair of virtual printers and the printer agent form a one-to-one communication connection, and each virtual printer 41 is in communication connection with the management platform 40 to receive the management of the management platform 40.

In some examples of this embodiment, the management platform 40 manages the printer search results reported by the printer agent 42. Please refer to an interaction flowchart between the management platform 40 and the virtual printer 41 shown in FIG. 5 below.

S502: The virtual printer reports the printer search result to the management platform.

In these examples, after the virtual printer receives the printer search result reported by the printer agent, it can report the printer search result to the management platform, so that the management platform also knows the printer device deployment status on the printer agent side.

S504: The management platform processes the printer search result according to the deployment area of the client and the printer deployment location in the printer search result to obtain printer indication information.

In these examples, the printer search results include not only the identification information of each printer, but also the deployment location of each printer. After obtaining the printer search results, the management platform can determine the physical properties of each printer searched by the printer agent. position. At the same time, because the management platform can obtain the deployment area of each client, based on the deployment area of the client and the deployment location of each printer, the management platform can determine the distance between the client and each printer (or the distance between the client and the printer from the location of the client). Difficulty), and then filter based on distance, the management platform can determine the actual printers available to the client. Then the management platform can generate printer indication information based on the printers actually available on the client, and use the printer indication information to indicate to the corresponding virtual printer the printers actually available to the printer agent.

In some examples of this embodiment, the management platform can directly delete printers that are actually unavailable by the printer agent from the printer search results, and only keep the printers that are actually available, so as to obtain printer instructions. Therefore, in these examples, the printer The instructions are actually a shortened version of the printer search results.

In other examples, the management platform determines which printers in the printer search results are actually available to the client and which are actually unavailable to the client. It can mark each printer to generate printer instructions, for example, In this example, the printer instruction information still includes the information of all printers in the printer search results, but some of the printers are marked as "unavailable".

S506: The management platform sends the printer instruction information to the virtual printer.

After the management platform generates printer instructions, it can send the printer display to the corresponding virtual printer (that is, the virtual printer that reports the printer search results). After receiving the printer instructions, the virtual printer can display the printer instructions to the user for The user can refer to it when selecting the task performer. Of course, according to the previous introduction, in some examples, the process of selecting the task performer is completed by the virtual printer itself. In these examples, the virtual printer does not need to display the printer instructions after receiving the printer instructions. For the user, it is used when selecting the corresponding task performer for the user's job requirements.

In the above examples, the management platform mainly manages the availability of the printers corresponding to each virtual printer, but in some other examples, the management platform can also manage other affairs. For example, after the virtual printer generates the job task, it can report the job task to the management platform. In some examples, the virtual printer reports job tasks to the management platform only for the purpose of allowing the management platform to record the job tasks. Therefore, in these examples, the virtual printer can generate the job task before sending it to the printer agent. Report the job task to the management platform, or first send the job task to the printer agent and then report the job task to the management platform. In some other examples, the virtual printer performs job task issuance and report simultaneously.

In some other examples of this embodiment, if the job task generated by the virtual printer is a printing task, after the virtual printer reports the printing task to the management platform, the management platform can record the printing content involved in the printing task, for example, it can treat The printed content is archived. If the job task is a scan task or a copy task, in some examples, the printer agent can upload the copied content or scanned content as the job result to the virtual printer after completing the job task, and the virtual printer can receive feedback from the printer agent After the result of the operation, upload the result of the operation to the management platform for archiving.

In the above examples, the timing of the virtual printer reporting job tasks to the management platform can be arbitrary. This is mainly because the management platform only records the job tasks or records the print content. However, in other examples of this embodiment, the management The platform can also review the job tasks, please refer to a flow chart shown in FIG. 6.

S602: The virtual printer reports the job task to the management platform.

S604: The management platform reviews the job task based on at least one of the user authority and the printer authority.

S606: The management platform feeds back a job instruction to the virtual printer based on the audit result.

For example, take the enterprise-level management platform as an example. Because each employee in the enterprise has different permissions, the management platform can review job tasks based on user permissions and whether users have corresponding job permissions; or because different printers have different confidentiality Therefore, when processing confidential documents, each printer has different permissions. The management platform can review the current job tasks based on the printer permissions and determine whether the corresponding task performer is qualified to perform the corresponding task. If the judgment result (that is, the audit result) is yes, the permission instruction can be fed back to the virtual printer as the job instruction, and if the judgment result is no, the prohibition instruction can be fed back to the virtual printer as the job instruction. The virtual printer will continue to deliver job tasks to the printer agent on the client side only after receiving a positive permission instruction. Otherwise, the virtual printer can refuse to continue to perform job tasks. For example, it can report user permissions on the cloud desktop. Insufficient prompt message or information about insufficient printer authority.

The printer usage method provided in this embodiment does not need to use redirection technology to redirect the printer on the client side to the cloud desktop side. Therefore, the local ordinary PC on the client side can use these printers, and at the same time, because the cloud desktop side can also The use of printers is realized based on the cooperation of printer agents and virtual printers, and the printers used are not limited to the local printers on the client side, but also include network printers, shared printers, etc., thus avoiding repeated deployment of printers, reducing printing costs, and benefiting Realization of optimal allocation of resources.

Moreover, for the many virtual printers of many cloud desktops, a management platform can be set up for management. For enterprises, governments and other institutions, it can better manage printer resources, count and archive job tasks, and benefit the physical organization of the organization. Maintenance of asset and information security.

Please refer to the printer usage shown in FIG. 7 Schematic.

In FIG. 7, the first printer 77 can be any one of a USB interface, a serial port, or a parallel port printer, and it is connected to the thin client 72. There are also a PC 74 and a second printer in the network where the thin client 72 is located. 75. The second printer 75 is a shared printer or a network printer. The client 72 corresponds to the cloud desktop 73 on the cloud platform side, and there is a communication connection between the two. A printer agent is deployed on the client 72, and a virtual printer is deployed on the cloud desktop 73. A management platform 76 for managing virtual printers is also deployed on the cloud platform side.

S822: The management platform feeds back the permission instruction to the virtual printer.

In this embodiment, it is assumed that the management platform has passed the review of the print task, so it can feed back the permission instruction to the virtual printer. However, if the management platform fails to pass the review of the print task, it can feed back the prohibition instruction to the virtual printer. After receiving the prohibition instruction, the virtual printer can close the print task, and send a prompt to the user, prompting the user the reason for the closing of the print task.

S824: The virtual printer issues the printing task to the printer agent according to the permission instruction.

S826: The printer agent selects the corresponding printer from the local network to execute the printing task.

In this embodiment, through the search of the printer agent, the cloud desktop side can obtain the information of the first printer and the second printer, and when the cloud desktop user has a printing demand, the first printer and the second printer can be obtained from the first printer and the second printer as needed. Select the device that executes the printing task in, so that the cloud desktop user can use the first printer and the second printer without redirecting the printer. At the same time, because the first printer is not redirected to the cloud desktop side, the PC can not only use the second printer, but also the first printer. Therefore, the printer use solution provided by this embodiment can effectively utilize existing printers to provide services to users without increasing hardware costs, allowing users to be more versatile, flexible, and more flexible when performing print jobs.
