Medium.Its collective's application scenarios is that file to be printed is uploaded to server by way of app or others by user, by
Server progress file turns shelves, when server completes after turning shelves of file, after sending format conversion to preset printer
File, and then printing for file is completed by printer.Below by multiple embodiments to scheme provided by the present application into
Row explanation.
Embodiment one
It is a kind of flow chart for file to be printed format conversion method that the embodiment of the present application one provides referring to Fig. 1, Fig. 1.
File to be printed format conversion method provided by the present application, applied to connection printing device server in, file to be printed lattice
Formula conversion method includes:
S101 obtains file to be printed；
In step S101, file to be printed is obtained；Specifically include that server receives user and passes through the APP on intelligent terminal
Or the file that default platform uploads, the format of file to be printed does not clearly require at this time, can be the text of pdf format
Part, naturally it is also possible to be the file of the extended formattings such as doc, docx.
It is to be understood that often there are multiple users in practical application while using the scene or same of printer
The case where one user prints more parts of files simultaneously, so in order to preferably distinguish each file, and to printing each file respectively,
When receiving the file of user's upload, the file generated based on receiving is needed to encode correspondingly with file, or in user
When upper transmitting file, APP or default platform are just numbered file, and generation is numbered correspondingly with file.
When APP or default platform are just numbered file, generate with file correspondingly number when, server can
To receive the file to be printed and number corresponding with file to be printed that client or default platform upload；It stores later to be printed
File obtains the storage address of file to be printed；Also, the storage address of file to be printed is stored in redis storage system
And number；It should be understood that when, since number is corresponded with file to be printed, and file to be printed and file to be printed are deposited
It stores up address to correspond, so number and the storage address of file to be printed correspond.It is stored in redis storage system
When, numbering with the storage address of file to be printed is also to be stored correspondingly.
It is to be understood that redis storage system is a key-value storage system.It is similar with Memcached, it
Support the value type of storage relatively more, including string (character string), list (chained list), set (set), zset
(sorted set-- ordered set) and hash (hash type).These data types all support push/pop, add/remove
And intersection union and difference set and richer operation are taken, and these operations are all atomicities.On this basis, redis branch
Hold the sequence of various different modes.As memcached, for guaranteed efficiency, data are all to cache in memory.Difference
It is the record file that redis can periodically operate write-in addition the data write-in disk of update or modification, and
It is synchronous that master-slave (principal and subordinate) is realized on the basis of this.
Redis is a high performance key-value database.The appearance of redis, largely compensates for
The deficiency of this kind of key/value storage of memcached, in part, occasion can play supplement well to relational database and make
With.It provides Java, C/C++, C#, PHP, JavaScript, Perl, Object-C, Python, Ruby, the visitors such as Erlang
Family end, it is very convenient to use.
Redis supports master-slave synchronisation.Data can be synchronized from server from primary server to any number of, from service
Device, which can be, is associated with other primary servers from server.This makes Redis that single layer tree copying can be performed.Deposit can intentional nothing
Meaning carries out write operation to data.Due to fully achieving publish/subscribe mechanism, so that from database anywhere synchronization tree
When, a channel can be subscribed to and receive the complete news release record of primary server.Synchronize to the scalability of read operation and
Data redundancy is helpful.
Server and printer are accessible and modify, the content in redis storage system.
File to be printed is converted to prn file by S102；Wherein, prn file is identifiable for printing device, and can be straight
Connect the format for printing；
Although, for the printer of different brands, being saved in it should be noted that prn file extension name is all .prn
The content format of prn file on hard disk be not be completely fixed with it is consistent.This is because each prn file is inherently
It is made of the print command of certain specific printer, i.e., prn file is equivalent to a kind of driving journey for particular printer
Preface part.So the file that different printer drivers generates is not fully identical, this prn file is usually that can not read
Or be converted to extended formatting.Even if once in a while can successful conversion format, also tend to and have more or less difference in source file
It is different.
Further, it in step S102, in order to which the prn file printing device made is identifiable, and can be directly used for beating
The format of print；The transformation of the format of file to be printed is carried out using the virtual machine by matching with default printer.Example
The printer of Yichuan Yi Lian Science and Technology Ltd. as the application one is used in the examples, corresponding virtual machine should using with
The transit telegram text fictitious host computer that the printer of Yichuan Yi Lian Science and Technology Ltd. matches, so set, can make virtual machine with
Printer matches, and the printer that the prn file that virtual machine is converted is predetermined is identified and printed.
Further, in step S102 provided by the present application, file to be printed is converted into prn file；It specifically includes:
S201, storage address and the file to be printed for obtaining the file to be printed stored in redis storage system are corresponding
Number；
It is to be understood that due to the characteristic of redis storage system: Redis supports master-slave synchronisation.Data can be from main clothes
Business device is synchronized from server to any number of, be can be from server and is associated with other primary servers from server.This makes
Obtaining Redis can be performed single layer tree copying.Deposit consciously or unconsciously can carry out write operation to data.Due to fully achieving hair
Cloth/subscribing mechanism so that from database anywhere synchronization tree when, a channel can be subscribed to and to receive primary server complete
News release record.So that when storing in redis storage system by numbering the storage address with corresponding file to be printed,
Server and fictitious host computer can quickly read the content stored in it, can obtain need to carry out format conversion later
File to be printed address.
S202, the storage address based on file to be printed obtain file to be printed；
It should be noted that server is to use Ali's Cloud Server in the application, it is particularly flat using OSS
Platform, OSS are a comprehensive service operation and management platform, while being also really to have merged Traditional IP data service to increase with mobile
The comprehensive management platform of value business.OSS is the support system of the integration of telecom operators, information resources share, it mainly by
The part such as network management, system administration, charging, business, account and customer service forms, and passes through unified bus between system
Organic combination is together.It can not only help true while helping operator to work out and meeting the Operation Support System of own characteristic
Determine the developing direction of system, moreover it is possible to help the integration standard of user's brakstaff, improve the service level of user.
It is also to be stored by OSS platform when storing file to be printed in above-mentioned step S101.So in step
In S202, the storage address of file to be printed generated when easily can store file to be printed according to step S101 obtain to
Mimeograph documents.
S203 converts prn file for file to be printed by preset virtual machine；
It should be noted that preset virtual machine is the transit telegram text fictitious host computer to match with printer.It needs to illustrate
It is that it dedicated for carrying out transit telegram text (that is: is prn file by the format conversion of file to be printed that transit telegram text fictitious host computer, which is a kind of,
Fictitious host computer), function be printer driver in, convert file to be printed to the function for the file that printer can identify
Energy.So set, the conversion of the format of document can directly be carried out by the server in distal end or cloud, woth no need to pass through local
Smart machine conversion file to be printed format.
S204 stores prn file, obtains the storage address of prn file；
It should be noted that start carry out file format conversion when, be page by page convert, conversion complete
One page just stores one page, and the storage address of the prn file after conversion, can be with it has been determined that so step S204 and step S203
Regard as while carrying out, when starting the file conversion for carrying out step S203, does not convert a part and just store a part.
S205 stores the storage address and number of prn file by redis storage system；
It should be noted that, for same number in redis storage system, being stored with correspondence after completing step S205
File to be printed storage address and prn file storage address.
S201 through the above steps, step S202, step S203, step S204, step S205 can be completed for file
Format standard change, convert prn file for file to be printed.
S103 is converted into prn file to printer transmission.
Step S103, specifically includes: obtaining the acquisition file request that printer is sent；Wherein, obtaining file request includes:
Number；Based on number, prn file is sent to printer.
It should be noted that in redis storage system, the upload of storage address and number based on multiple groups file to be printed
Time forms print queue；
Obtaining file request is that printer is generated based on number；It is one of to number a corresponding acquisition file request；
Printer is according to print queue sequential in accordance with generating and sending acquisition file request.
So set, the file to be printed first uploaded can be made preferentially to print, according to be printed after file uploads
The uplink time of file is ranked up volume, and printer sends print request according to the time sequencing of number, such as: number is
074 file first uploads, and the file that number is 075 later starts to upload.Printer sends override requests when obtaining file request
The file that printing number is 074, after the file process that number is 074 is completed or determines mission failure, printer transmission is obtained
Take the file that file request request printing number is 075.
Further, based on number, prn file is sent to printer, is specifically included:
Based on number, the storage address of prn file is determined；Wherein, prn file includes at least one prn subfile；Each
Prn subfile, for being obtained by printer, and one page page by printer based on prn subfile print preset paper；It needs
Illustrate, the prn file after conversion is divided into multiple prn subfiles, each prn subfile pair according to the page of printing herein
Answer the complete page to be printed of one page.
Whether judge in prn file comprising at least one unprinted prn subfile；
If it exists, prn subfile is sent to printer, and will successively sends each prn subfile to printer.
So set, when a file to be printed have multipage when, and in file to be printed a part of page format
It is inverted be prn file, can preferentially print at this time conversion text at prn subfile, realize document to be printed side conversion become
Printing, while formatting, carries out the printing for the prn subfile for converting part.
Certainly, if prn subfile is not present in prn file, it is not responding to the acquisition file request of printer transmission.
After printer sends the same number corresponding acquisition file request preset times, or the continuous same number pair
After the acquisition file request answered sends preset time, prn subfile or prn file are not obtained yet, then send task to server
Failure information；
Such as: printer can be set after not receiving to the response for obtaining file request of server passback, 10s
Identical acquisition file request can be sent herein later, so recycled, if in preset times (such as having sent 3 times) or default
In time (such as distance send total 30s for the first time time after) receive yet server passback for acquisition file request
Response then confirms that this print out task fails, and printer sends mission failure information to server；Wherein, mission failure information
It include: number.
Server receives after mission failure information, and the corresponding print out task of number that label mission failure information includes loses
It loses.And the information of printing failure is sent to user.
File to be printed format conversion method provided by the present application, applied to connection printing device server in, first
Obtain file to be printed；File to be printed is converted into prn file；Wherein, prn file is identifiable for printing device, and can
It is directly used in the format of printing；Prn file is converted into printer transmission.So set, user only need to send band to server
The document of printing can use printer completion to turn shelves for file, virtual without the smart machine downloading by oneself
Machine not only effectively avoids installation virtual machine bring inconvenient, while virtual machine being avoided to give user oneself smart machine band when running
The load come.
