Detailed Description
In order to make the purpose, technical solution and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments, and it is obvious that the embodiments described below are part of the embodiments of the present invention, and are used for illustrating the present invention only, but not for limiting the scope of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The cloud printing server and the intelligent printing method of the remote printing equipment provided by the invention can be applied to a remote printing scene shown in figure 1. The service device and the remote printing device may be, but are not limited to, various personal computers, notebook computers, smart phones, and tablet computers, and are all multiple, and the cloud print server may be implemented by an independent server or a server cluster formed by multiple servers. The cloud printing server can maintain the working state reported by the remote printing equipment at regular time, receive and manage the remote printing request of the service equipment, judge whether to create a new remote printing task according to the working state of the remote printing equipment, and send the newly created remote printing task to the remote printing equipment which is connected with the cloud printing server and is bound with the printer to complete printing.
In one embodiment, as shown in fig. 2, there is provided an intelligent printing method of a cloud print server, the method including the steps of:
s11, establishing connection with a remote printing device, and receiving and storing the working state reported by the remote printing device;
the remote printing equipment is associated with enterprises and corresponds to one another, namely one enterprise corresponds to one remote printing equipment, and the mapping relation is stored in an enterprise-remote printing equipment mapping relation table on the cloud printing server and used for searching the remote printing equipment needing to issue the remote printing task when receiving the remote printing request. The cloud printing server and the remote printing equipment can establish communication connection through a TCP (transmission control protocol), a UDP (user datagram protocol) or an HTTP (hyper text transport protocol) protocol and are used for receiving the working state reported by the remote printing equipment and subsequent remote printing task issuing operation. After receiving the working state reported by the remote printing equipment, the working state and the storage time in the working state table of the printing equipment are updated, and the method is used for subsequently receiving the remote printing request to judge whether to create the printing task for use. In the embodiment, the communication connection mode between the cloud print server and the remote printing device preferably adopts TCP connection to ensure reliable transmission of data, so that the stability of remote printing is ensured.
S12, receiving a remote printing request of a service device, inquiring and obtaining a working state reported by the remote printing device;
as shown in fig. 3(a) - (b), a remote printing request is transmitted on a fast batch APP of the service device through a TCP, UDP, or HTTP protocol, where the remote printing request includes enterprise information and a document or document to be printed. After receiving the remote print request, the cloud print server searches for a working state of the corresponding remote printing device according to the content of the remote print request, as shown in fig. 4, where the step S12 of receiving the remote print request of the service device, querying and obtaining the working state reported by the remote printing device includes:
s121, searching the bound remote printing equipment according to the enterprise information corresponding to the remote printing request;
the enterprise information may be an enterprise account or other similar information that may be used to identify and distinguish different enterprises. And when receiving the remote printing request, the cloud printing server searches the corresponding remote printing equipment in the enterprise-remote printing equipment mapping relation table according to the carried enterprise information for issuing a subsequent printing task.
S122, searching the working state reported by the remote printing equipment and judging whether the time for reporting the working state exceeds the preset time, if so, actively acquiring the working state of the remote printing equipment.
The working state of the remote printing device is maintained in a working state table of the remote printing device of the cloud printing server, and after the corresponding working state record is found by the remote printing device, whether the difference value between the storage time in the working state record and the receiving time of the remote printing request exceeds a preset time length is judged, wherein the preset time length can be set according to an actual situation, and the preset time length in the embodiment is set to be 1 minute. If the time does not exceed 1 minute, the working state can be directly used as the working state of the current remote printing device, that is, when the record in the working state table is in a normal state, the current remote printing device is considered to be capable of receiving the remote printing task, and when the record in the working state table is in an abnormal state, the current remote printing device is considered to be abnormal and the remote printing task cannot be distributed. On the contrary, if the time exceeds 1 minute, the working state of the remote printing device stored on the cloud printing server is considered to be overtime and cannot represent the real working state of the current remote printing device, at this time, the cloud printing server needs to actively send a working state request to the remote printing device, the working state fed back by the remote printing device is used as the working state of the current remote device, and if the working state fed back by the remote printing device cannot be received, an abnormal prompt 'connection interruption between the cloud printing server and the remote printing device' is given. According to the embodiment, the overtime detection and active state acquisition mechanism for the working state of the remote printing equipment effectively guarantees the real-time performance of the working state of the remote printing equipment, and further improves the processing efficiency of the remote printing request.
S13, creating a printing task according to the working state reported by the remote printing equipment and the remote printing request, and sending the printing task to the remote printing equipment;
the working state reported by the remote equipment comprises a normal state and an abnormal state. The cloud print server may determine whether the remote print request can create the print job according to the queried working state and the print job amount that the remote device has already taken over currently, and refuse the remote print request when determining that the print job cannot be created, and give an exception prompt, as shown in fig. 5, the step of creating the print job according to the working state and the remote print request reported by the remote print device includes:
s131, when the working state reported by the remote printing equipment is a normal state and the number of the printing tasks of the remote printing equipment is less than a specific numerical value, allocating a task ID and creating the printing tasks;
the number of the print tasks is used for counting the number of the print tasks carried by the remote printing equipment by the cloud printing server, when the cloud printing server detects that the working state of the remote printing equipment is a normal state, namely the print tasks can be accepted in principle, the problem of queuing of the print tasks of the remote printing equipment is further considered, a specific numerical value is set as an upper queuing limit, and whether the number of the print tasks of the current remote printing equipment reaches the upper queuing limit needs to be considered. It should be noted that in this embodiment, the specific value of the upper limit of the number of print jobs corresponding to each remote printing device is 20, and the specific value can be adjusted according to actual situations. When the remote printing equipment can continue to bear the printing task, the task ID is distributed and the printing task is created according to the remote printing request, the remote printing request of the service equipment is converted into a corresponding printing instruction, the corresponding printing instruction is stored as a file and is uploaded to an OSS (object Storage service), and a downloading URL is generated for subsequent printing use. In the embodiment, the print file is stored by using an object with high reliability, high availability and high performance of OSS, and the number of print tasks corresponding to the remote printing equipment is updated after the task creation is completed for detecting the subsequent created task, so that the processing efficiency of the remote print request is well ensured.
S132, when the working state reported by the remote printing equipment is a normal state and the number of the printing tasks of the remote printing equipment is equal to a specific numerical value, or when the working state reported by the remote printing equipment is an abnormal state, rejecting the remote printing request and giving an abnormal prompt.
In the method, because the number of the printing tasks which can be carried by the remote printing equipment is considered, even if the current working state of the remote printing equipment is a normal state, after the task amount exceeds a preset specific numerical value, the remote printing request can be rejected in order to avoid overlong queuing of the service equipment, and meanwhile, corresponding abnormal prompts are given, namely that the current remote printing tasks exceed 20, the task sending fails, and the task sending is required to be retried later.
When the working state reported by the inquired remote printing equipment is an abnormal state, the remote printing request can be directly rejected, and a corresponding abnormal scene is given to give a corresponding abnormal prompt, if a printer is not set, the Bluetooth is not started in Bluetooth printing, wifi printing is not connected with wifi, and the like.
The problem that printing data transmission is failed and unknown easily occurs in the remote printing process, unnecessary time waste of a remote printing user at a service equipment end is caused, a monitoring mechanism is provided for judging whether data transmission issued by a printing task is successful or not, namely, after the cloud printing server sends the created printing task to the remote printing equipment, the state of the printing task is marked to be pushed, whether a printing task receiving response of the remote printing equipment is received or not is detected in real time, if the printing task receiving response is not received, the printing task sending failure is judged, and an abnormal prompt 'printing data transmission failure, connection or interruption' is displayed on the service equipment.
In the embodiment, the cloud print server gives a corresponding abnormal prompt when rejecting the remote print request, so that a service equipment end user can know the problem of abnormal printing in time, user experience is greatly improved, and the working efficiency is improved to a certain extent.
And S14, receiving the printing result fed back by the remote printing equipment, and sending the printing result to the service equipment.
The printing result comprises successful printing, failure in connecting the printer, failure in finding the configured printer, request for reconfiguring the printer, failure in generating printing data, overtime failure of system detection and the like, and the remote printing equipment feeds back the actual printing result to the cloud printing server for displaying on the service equipment, so that a user of the service equipment can check and judge whether to reprint the printing result, and smooth completion of a printing task is ensured.
In the embodiment, the cloud print server receives and maintains the working state of the remote printing equipment, and searches the corresponding remote printing equipment according to the remote printing request after receiving the remote printing request of the service equipment, creating a printing task according to the working state reported by the remote printing equipment and sending the printing task to the remote printing equipment to execute printing, and the received printing result or the abnormal prompt of creating the printing task is sent to the service equipment for the service equipment to check and process, so that the cloud printing server uniformly receives and manages the remote printing request of the service equipment, the method and the device have the advantages that safe and reliable printing file storage and reasonable and effective task distribution are provided, the reliability of multi-terminal, multi-member, cross-region and cross-network remote printing is guaranteed, the perception of a local printer to cloud service is avoided, the remote printing efficiency is improved, and meanwhile the user experience is improved.
In one embodiment, as shown in fig. 6, there is provided an intelligent printing method of a remote printing apparatus, the method comprising the steps of:

After receiving the print task sent by the cloud print server, the remote printing device sends a receiving response of the print task to the cloud print server, so that the cloud print server detects whether the print task is failed to be sent.
S23, sending a printing instruction to a printer according to the printing task;
the printing instruction is generated when the number of the tasks to be printed is 0, namely the current printer does not have the printing tasks, the printing data is downloaded to the cloud printing server through wget according to the ID of the printing tasks, the printer is connected, the printing data is sent to a 9100 printing port through nc, and printing is initiated. If the number of the tasks to be printed is not 0, namely the current tasks are printed, adding the printing tasks of the new catcher into a printing task queue, subsequently executing the printing tasks according to a first-in first-out principle, downloading printing data to a cloud printing server through wget according to the ID of the printing tasks to generate a printing instruction when the printing tasks are executed, connecting a printer, sending the printing instruction to a 9100 printing port through nc, and initiating printing. The size of the print job queue of the remote printing apparatus can be set according to the actual situation, and is set to 20 in the present embodiment. It should be noted that when the downloading of the print data fails, the connection of the printer fails, or the sending of the print data fails, there are corresponding abnormal prompts, such as "failure to generate print data", "failure to connect the printer", "failure to find a configured printer, please reconfigure the printer", "failure to transmit the print data, connection or interruption", or "failure to detect timeout by the system", and the like, and the print result of the print failure is fed back to the cloud print server.
And S24, receiving the printing result fed back by the printer, and sending the printing result to a cloud printing server so that the cloud printing server feeds back the printing result to the service equipment.
The remote printing equipment sends the printing result fed back by the printer to the cloud printing server, and the cloud server sends the printing result to the service equipment to display and inform a user whether printing is successful or not, so that the user can decide whether reprinting is needed or not.
In the embodiment, the remote printing equipment controls whether to receive the printing tasks sent by the cloud printing server in communication connection with the remote printing switch, reports the working state monitored in real time to the cloud printing server for receiving the remote printing request of the service equipment and judging whether to create the tasks for use, acquires printing data from the cloud printing server according to the task ID after receiving the printing tasks, generates a printing instruction and sends the printing instruction to the binding printer, and sends the printing result fed back by the printer or the abnormity of the executed printing task to the cloud printing server for checking and processing to the service equipment, so that the method realizes that the local printing tasks are uniformly managed by one remote printing equipment, realizes multi-terminal, multi-member, cross-region and cross-network remote printing, improves the remote printing efficiency, and effectively avoids the perception and adaptation of the printer to the cloud printing server, the printer is perfectly compatible with different printer models, and the remote printing cost is further reduced.
