The user end 12 communicates with the server 14 through the network, and the user end 12 can upload the print file through the network; the server 14 receives the print file uploaded by the user end 12, stores the print file, and performs fragmentation and format conversion on the print file to obtain a first format file; the server 14 sends the first format file to the printing cloud box 16; the printing cloud box 16 controls the off-line printer 18 to complete printing. The client 12 may be, but is not limited to, various smart phones, personal computers, notebook computers, and tablet computers, and the server 14 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
The cloud printing method based on the file fragments can be used for internet printing, and fast and efficient cloud printing service is achieved.
In an embodiment, fig. 2 is a flowchart of a first file fragment-based cloud printing method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
step S210, acquiring a print file, and segmenting the print file according to a preset segmentation strategy to generate a segmented file;
in step S210, the server 14 receives and stores the print file, and then selects an adaptive fragmentation mode to fragment the print file according to a preset fragmentation policy and the size of the received file, for example: the preset slicing strategy is that when the number of pages of the file is more than or equal to 10 pages, slicing is not performed; when the number of pages of the file is more than 10 and less than 100, taking every 10 pages as one fragment; when the number of pages of the file is greater than or equal to 100 pages, every 20 pages are taken as one shard; when the received file is 18 pages, the file is divided into a 10-page fragmentation file and an 8-page fragmentation file according to the above-mentioned policy, and the fragmentation policy can be adjusted according to the specific application environment, such as the storage capacity of the printing cloud box 16, the network configuration of the printer, and the like.
Step S220, carrying out format conversion on the fragment file to obtain a first format file, wherein the fragment file corresponds to the first format file, and a storage path of the first format file is obtained;
in step S220, the server 14 performs format conversion on the fragmented file to convert the fragmented file into a first format file, where the first format file is a uniform format that is convenient for the printer to recognize, and at the same time, stores the obtained first format file and records a storage path of the first format file.
Step S230, sending a storage path to the printing cloud box 16, where the printing cloud box 16 downloads the first format file according to the storage path and instructs the printer to print;
in this step S230, the server 14 sends the storage path of the first format file to the printing cloud box 16, and the printing cloud box 16 sequentially downloads the first format file corresponding to each fragment file according to the received storage path of the first format file, and then instructs the printer to sequentially print. Taking the above fragment file as an example, two fragment files generated from 18 pages of files are respectively converted into two first format files, two storage paths exist correspondingly, the printing cloud box 16 downloads the corresponding first format files according to the corresponding received storage paths, for example, the printing cloud box 16 downloads the first format file obtained by converting the first 10 pages of fragment files, and sends the first format file to the printer for printing, and in the printing process of the printer, the printing cloud box 16 continues to download the first format file obtained by converting the second 8 pages of fragment files, and then sends the first format file to the printer for printing.
Through the steps of the method, the server 14 fragments the received print file according to a preset fragmentation strategy, then performs format conversion on the fragmented file, converts the fragmented file into a uniform first format file and acquires a storage path of the first format file, then sends the storage path to the print cloud box 16, the print cloud box 16 downloads the first format file according to the storage path and instructs the printer to print, and the cloud printing method fragments the print resource and converts the fragmented file into the first format file and then transmits the first format file to the printer, so that the influence of network conditions on file transmission is reduced, the printing efficiency of the printer is improved, and the problem that slow printing or even failure frequently occurs in cloud printing service is solved.
In an embodiment, after performing format conversion on the fragmented file to obtain a first format file, the server 14 obtains a file conversion status of the first format file, where the file conversion status indicates a result status of format conversion of the fragmented file, such as conversion success or conversion failure; under the condition that the file conversion state is failure, the fragment file is obtained again for format conversion; the method comprises the steps that when the number of times of file conversion state continuous failure is larger than a preset value, the fragment file is stopped being obtained, for example, a manager of a printing system sets the preset value to be 5 times according to user requirements, and then when file format conversion is continuously performed for 5 times and conversion failure is displayed, the conversion process is stopped.
In one embodiment, the server 14 sends the storage path to the print cloud box 16, and the print cloud box 16 downloads the first format file according to the storage path, and instructs the printer to obtain the print status of the printer after printing the first format file, for example, the print cloud box 16 succeeds in printing or fails in printing; when the printing state continuously indicates that the number of times of printing failure is greater than the preset value, the printing cloud box 16 sends a message of printing failure to the server 14, for example, a manager of the printing system sets the preset value to 4 times according to a user requirement, and then sends the message of printing failure to the server 14 after the printing cloud box 16 acquires the state of printing failure from the printer for 4 times continuously; after receiving the message of printing failure sent by the printing cloud box 16, the server 14 acquires the fragmented file corresponding to the first format file according to the message, and sends the information of the fragmented file to the user end 12, and the user end 12 may browse the contents of the fragmented file that is not successfully printed on the page, and then perform further operations, such as abandoning printing or reprinting. The embodiment mode provides a solution to the printing failure, and the printing solution is more complete by acquiring the content of the fragment file which fails to be printed and visually presenting the content to the user terminal 12.
In an embodiment, after obtaining the storage path of the first format file, the server 14 generates a fragment cache table according to the storage paths of the print file and the first format file, where the print file and the storage path of the print file fragment and the first format file obtained after format conversion may be stored in the cache table, and the two may be mapped one to one, and in addition, the total number of fragment files after the print file fragment may be recorded, where the current fragment is the second fragment, and information such as the conversion state and the print state of the fragment is convenient for management; after the server 14 obtains the print file, the fragment cache table is searched first, and when the record of the print file exists in the fragment cache table, the storage path of the first format file corresponding to the print file is obtained, and the first format file can be directly sent to the print cloud box 16 without going through the processes of fragmentation and format conversion again.
In an embodiment, fig. 3 is a second flowchart of a file fragment-based cloud printing method according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:
step S310: the printing cloud box 16 receives a storage path of a first format file sent by the server 14, wherein the server 14 fragments the printing file according to a preset fragmentation strategy to generate a fragmented file, and performs format conversion on the fragmented file to obtain the first format file;
in this step S310, after the server 14 fragments and converts the format of the print file to obtain the first format file, the print cloud box 16 receives the storage path of the first format file sent by the server 14. Specifically, the server 14 receives and stores the print file, and then selects an adaptive fragmentation mode to fragment the print file according to a preset fragmentation policy and the size of the received file, so as to obtain a fragmented file, performs format conversion on the fragmented file, and converts the fragmented file into a first format file, where the first format is a uniform format convenient for a printer to identify, and meanwhile, the server 14 stores the obtained first format file, records a storage path of the first format file, and sends the path to the print cloud box 16.
Step S320: the printing cloud box 16 downloads the first format file according to the storage path, and instructs the printer to print the first format file;
in this step S320, the print cloud box 16 downloads the first format file according to the storage path and instructs the printer to print.
In this embodiment, the printing cloud box 16 receives the first format file storage path sent by the server 14, downloads the first format file according to the storage path, and sends the first format file to the printer, and the printing cloud box 16 has a scheduling function of caching the first format file and performing a printing process, for example, it is detected that the printer is printing the current first format file, and another first format file can be downloaded in the time slot, so that the printing efficiency is improved.
In one embodiment, the print cloud box 16 downloads the first format file according to the storage path, and instructs the printer to obtain the print status of the printer after printing the first format file, for example, the print status is successful or failed; if the state returned by the printer is printing failure, the printing cloud box can send the first format file to the printer again and instruct the printer to print the first format file so as to solve the problem of occasional printing failure of the printer, and the total number of times of sending the first format file to the printer by the printing cloud box is less than or equal to a preset value; when the number of times of printing failure continuously indicated by the printing state is greater than a preset value set by a manager of the printing system according to user requirements, the printing cloud box 16 sends a message of printing failure to the server 14, for example, the preset value is set to 4 times, then, when the printing cloud box 16 acquires the printing failure state from the printer for 4 times continuously, the current first format file is stopped from being sent to the printer, and meanwhile, the next first format file is stopped from being acquired.
Fig. 4 is a schematic view of an application scenario of a cloud printing method based on file fragmentation according to another embodiment of the present invention, as shown in fig. 4, the server 14 is composed of an information management server 42, a file conversion server 44 and a file management server 46, preferably, the information management server 42 and the file management server 46 are servers of linux system, and the file conversion server 44 is a server of windows system; in a specific embodiment, the pdf aggregate file uploaded to the information management server 42 is divided into a plurality of pages according to a paging policy, where the fragmentation policy used here is 1599 policy, that is, the first part of the fragment contains 1 page file, the second part contains 5 pages file, and the third part contains 9 pages file in each paging file, and the files are stored in the information management server 42.
Sending information such as a file storage path, a virtual printer index number, and the number of the segmented files of the first segmented file to the file conversion server 44, that is, sending a file conversion service request to the file conversion server 44, where the virtual printer is a virtual printer on the file conversion server 44 and functions to convert files in other formats such as pdf into files in the first format; and creating a queue according to the fsc _ + virtual printer index number, sequentially putting the rest fragment file information into the queue, creating a stack named as sub _ fsc _ + virtual printer index number, and storing the first fragment file information into the stack.
The file conversion server 44 downloads the fragment file according to the storage address of each fragment file provided by the information management server 42, finds the virtual printer on the file conversion server 44 by the virtual printer index number, converts the pdf-formatted file into the file format recognized by the printer, and transmits the converted file to the file management server 46;
the information management server 42 receives the virtual print request response returned from the file conversion server 44, queries whether a print record corresponding to the pdf master file exists, and changes the print record status, for example, changes an unprinted status in a print record into printing, where the print record is a database that records details of the print file and conversion and print statuses, and the database may be established in redis.
The information management server 42 communicates with the file management server 46 and receives a message from the file management server 46 containing the size and storage path of the first format file.
After receiving the message, the information management server 42 executes the following steps:
judging whether a queue named by 'fsc _' + virtual printer index number exists, if so, taking out the next fragment file in the queue, sending the next fragment file to the file conversion server 44 for processing, and repeating the steps until all the fragment files are completely converted, and deleting the queue;
if the file conversion fails, the information management server 42 extracts the stack top information in the stack named by the sub _ fsc _ "+ virtual printer index number, transmits the stack top information to the file conversion server 44, and the process is repeated for a limited number of times, for example, three times, if the number of times is used up, the database is updated, the conversion failure is displayed, the current stack is emptied, and the remaining files in the queue are extracted;
the information of the first format file received by the information management server 42 is updated to the memory of the information management server 42, and the first format file at this time is not the first format file generated by the complete print file but the first format file generated by the fragment file.
Further, the information management server 42 creates a queue based on the index number of the offline printer 18, stores the received first-format file information;
searching information of the offline printer 18, sending information of a first format file which is firstly queued, such as printer index numbers corresponding to printed files, the number of split files and the like to the printing cloud box 16, popping the information from the queue, pushing the information to a stack named by the index number of the offline printer 18, and waiting for feedback of the printing cloud box 16;
and receiving a printing transaction information reporting request of the printing cloud box 16, wherein the request includes contents such as a printing state, a failure reason, a fragment serial number and the like.
After the printing cloud box finishes printing, the information management server 42 executes the following steps after receiving the printing cloud box message:
updating a first format file print record
If the print cloud box 16 judges that the file is not completely printed, returning to state of 3 (print is not completed), the information management server 42 obtaining a queue through the index number of the offline printer 18, inquiring the queue, checking whether the file still has the first format file of the fragment file, if so, sending the file to the print cloud box 16, simultaneously popping (pop) the current file, and pushing (push) the file to the corresponding stack;
if the print cloud box 16 returns a state of 2 (print failure), reading an element at the top of the stack from the stack storing the first-format file, resending the element to the print cloud box 16, performing the sending operation for a limited number of times, for example, three times, if the three times of operations are unsuccessful, determining that the fragmented file fails to be printed, the information management server 42 emptying the stack storing the first-format file according to a report request of the print transaction information of the print cloud box 16, popping redundant data in a queue storing the first-format file out of the queue, sending a first fragmented file of a new print file to the print cloud box 16, and so on; after printing fails, the information management server 42 updates the database state and reports the printing transaction information;
when the fragmented files fail to be printed, the printing cloud box 16 sends printing failure information to the information management server 42, the information management server 42 pushes out the rest fragmented files from the queue, and displays file information corresponding to the fragmented files which fail to be printed in the queue on the pages of the user side 12 to remind the user whether to reprint the pages;
before a printing transaction is reported, if the queue corresponding to the current printId contains the first format file information, the operation of sending the first format file information to the printing cloud box 16 is repeated, if all the fragments are printed successfully, the current stack is emptied, the database state is updated, then the printing transaction is reported, and a state is returned to 1 (printing is successful).
In addition, a fragment cache table is established during fragmentation, and the content recorded in the fragment cache table is as shown in table 1:
TABLE 1
The MD5 information in the table is information obtained by an information digest algorithm for ensuring the integrity and consistency of information transmission, and is unique for each print file, when a user accesses an interface, the MD5 is generated by a path name and a file name code of a file stored on the server 14, and when the user uploads the same print file again, the user searches for a fragment file stored in the server 14 through the MD5, directly queries the fragment information from the database, and notifies the print cloud box 16 of downloading, without a step of converting the file into a file of the first format through the file conversion server 44.
