Embodiment two,
Fig. 2 shows a kind of flow charts of the print control program of bill printer provided by Embodiment 2 of the present invention.This
Bill printer in embodiment is multiple food and drink printers, and so-called food and drink printer, which refers to, provides bill printing for catering industry
Used printer can need to print single vote evidence, rear kitchen bill etc. at corresponding according to user's point list business, according to
The family business of checking needs to print corresponding bill bill, needs to print corresponding rear kitchen bill according to outer attraction list business, takes out
Single vote according to etc..Correspondingly, the food and drink printer in the present embodiment specifically includes: setting collects money, places an order on foreground, for printing
The foreground printer of bill；And rear kitchen, the rear kitchen printer for printing the bill of preparing for a meal after placing an order are set.After in addition,
Kitchen printer can also further be multiple printers for being separately positioned on different rear kitchen functional areas, not of the same race for completing
The bill printing of the food product of class operates.Similarly, foreground printer further can also be separately positioned on different foregrounds to be multiple
The printer of functional area, to complete different types of bill printing operation.Certainly, the present embodiment also can be applied to except food and drink
Except other field, which is not limited by the present invention.As shown in Fig. 2, this method comprises:
Step S200: being directed to each bill printer respectively, generates printer task corresponding with the bill printer
Queue；According to the attribute information of the bill printer, the queue attributes of the printer task queue are configured.
Specifically, printer task corresponding with the bill printer can be generated for each bill printer in advance
Queue.For example, operating according to the addition of food and drink printer, corresponding printer task queue is established for it.Wherein, food and drink prints
The addition operation of machine is added according to the printing demand of each business, is such as put single business and is needed to print corresponding single vote evidence,
It may require that kitchen after the food and drink printer (foreground food and drink printer) for adding corresponding print point single vote evidence and printing is standby singly to need
The food and drink printer (rear kitchen food and drink printer) of kitchen bill afterwards.Alternatively, mesh can also be confirmed as the first time in bill printer
Corresponding printer task queue is generated for it when marking printer, which is not limited by the present invention.
Next, configuring the printer task team of the printer task queue according to the attribute information of the bill printer
The queue attributes of column.Wherein, the queue attributes of the printer task queue of printer task queue include: queue length, task
Polling cycle, task priority strategy, and/or retry strategy etc..Wherein, the attribute information of bill printer includes: printer
IP address, the address Mac, printer ID, printer supplier ID, printing model (such as serial ports, parallel port, network interface), business function
It can (such as foreground point single function, foreground gathering functions, rear kitchen prepare for a meal function), type of service etc..According to each bill printer
Corresponding different attribute informations configure the queue attributes information such as queue length of its printer task queue.For example, queue
Length can be determined according to business function, it is assumed that rear kitchen printer further comprises three and corresponds respectively to different rear kitchen functional areas
The printer in domain, then the length of task queue corresponding to each printer is according to the food product for including in its responsible functional area
Type and frequency of ordering determine.For another example, task polling cycle can also be determined according to business function, as corresponding to payment function
Printer task queue task polling cycle it is smaller, to meet the needs of user's immediate payment.Furthermore it is also possible into one
Step configures the processing strategie of each printer task queue, such as drop policy, degradation strategy or strategy of joining the team again.In short,
Task queue corresponding to each printer can be separately configured according to the attribute information of printer, to be flexibly met each
The business demand of a printer.
In addition, can both be first carried out in advance in this step for the operation that each task queue is configured, it can also be with the period
Property Dynamic Execution, for example, can every preset interval adjust a task queue queue attributes configuration；Alternatively, can also be with
The configuration of the queue attributes of its corresponding task queue is adjusted after adjusting occurs in the function of printer.In short, passing through above-mentioned side
Formula can be realized the mobilism configuration of task queue, so that the printing demand in different business stage be flexibly met.
Step S210: print out task is generated according to the business datum received, will be beaten with the bill that print out task matches
Print machine is determined as target printer.
Inventor has found that the present embodiment is related to multiple bill printers, and is used to touch in the implementation of the present invention
Specified printer can not be selected to carry out if the business operation (such as the single operation of user's point, user's delivery operation etc.) of sending service data
Printing.Therefore, the application scenarios of the present embodiment are different from the printer scene of conventional office space: in conventional office space
In, printer is usually large-scale printer, itself has the sophisticated functions such as queue management, and therefore, user issues printing
Specified printer can be manually selected by the option entrance in printer page before to be printed；However, in the present embodiment
Application scenarios in, bill printer is usually small-sized mini printer, itself does not have the sophisticated functions such as queue management,
Moreover, printer page is not present, therefore each bill printer is complete for a user when user triggers business operation
Unaware, it is based on above-mentioned both sides reason, causes user that can not actively select specified printer when triggering business operation
It is printed.However, needing multiple bills for corresponding respectively to different business function to beat again in the application scenarios of the present embodiment
Therefore the printing that the mutual cooperation of print machine could complete all kinds of bills in the present embodiment, is needed by the executing subject in the present invention
The bill printer to match with print out task is automatically selected according to the business datum received.Wherein, the execution in the present invention
Main body can be the disparate networks equipment of connection is established with bill printer, such as can receiving point single operation, delivery operation it is each
The background server of class business operation, or businessmans' management equipment such as POS machine.
Specifically, corresponding printer is automatically selected according to the type of business datum: determines the business datum received
Type of service corresponding to type and each bill printer；The ticket that the type of type of service and business datum is matched
It is determined as target printer according to printer.When it is implemented, when receiving business datum, firstly, according to the class of business datum
The default printing template that type selection matches with the type, is assembled into printing for the business datum received according to the printing template
Business datum.For example, generally comprising single time in corresponding printing template when the type of business datum is the single type of point
Information, pick-up prompt information etc., correspondingly, added on the basis of business datum according to printing template a little single temporal information, take
Print service data are obtained after meal prompt information.Then, the preconfigured attribute information of each candidate printer is obtained, it will be each
The type of service for including in the attribute information of printer is matched with the type of the business datum received, according to matching result
Select a printer as target printer from multiple candidate printers.Finally, according to the attribute information of target printer
And print service data generate print out task.
In addition, in this step, since many business scenarios are all likely to occur a large amount of concurrent business datums, for example, In
In the scene that multiple users pay with time point list, simultaneously, the executing subject in the present invention will receive simultaneously at same time point
Corresponding multiple voice and packet data concurrent service data are operated by multiple voice and packet data concurrent services.At this time, it may be necessary to be operated respectively for each voice and packet data concurrent service
Corresponding voice and packet data concurrent service data generate at least one print out task, and determine target print for each print out task respectively
Machine.Wherein, the quantity of the print out task generated for the corresponding voice and packet data concurrent service data of voice and packet data concurrent service operation needs basis
Practical business demand determines.For example, can be generated two for the point list business datum corresponding to single business operation and beat
Print task: the first print out task is the task of foreground printer print point list detail, so that foreground is settled accounts according to detail；The
Two print out task are the task that rear kitchen printer prints detail of preparing for a meal, so that rear kitchen is prepared for a meal.It can be seen that in the present embodiment
In corresponding scene, multiple voice and packet data concurrent service operations not only are likely to be received at same time point, moreover, needing further exist for being directed to
Each voice and packet data concurrent service operation generates multiple print out task, also, the quantity of the bill printer in the present embodiment is more, and each
The setting area of bill printer and configuration feature are different.Under this complex scene, need to handle by preset strategy
A large amount of voice and packet data concurrent service operation, to prevent from omitting print out task.When it is implemented, can by the following two kinds implementation extremely
A kind of few realization:
In the first implementation, each print out task of generation is cached into preset buffer queue, respectively needle
Target printer is determined to each print out task in buffer queue.Which can borrow when concurrent a large number of services operates at the same time
Help buffer queue that each print out task is orderly handled, to effectively prevent the loss of print out task.
In the second implementation, thread is distributed by multiple concurrently executing for tasks determine that each print out task institute is right
The target printer answered.For example, when receiving multiple voice and packet data concurrent service data simultaneously, it is concurrently multiple according to the quantity of business datum
Task distributes thread, to realize the concurrent processing of each print out task, to be obviously improved treatment effeciency.
Step S220: the print out task is added in printer task queue corresponding with the target printer.
Specifically, in the present embodiment, there is unique printer object (i.e. printer for each printer setup in advance
Mark), printer task queue corresponding to each printer is identified by printer object.Correspondingly, in this step
In, it is first determined printer object corresponding with target printer, then, it is determined that printing corresponding with the printer object
Machine task queue, to being added to the print out task in printer task queue corresponding with the target printer.
When it is implemented, controlling target print by multi-thread mechanism for the ease of being managed for each printer
Machine.Specifically, it for a bill printer, needs to open three threads and is controlled, respectively queue is joined the team thread, queue
Team's thread and state-detection thread out.Wherein, multiple bill printers can share above three thread, it is furthermore preferred that point
Safety pin is opened above three thread to each bill printer and is controlled.Inventor has found in the implementation of the present invention:
Control accuracy can be obviously improved by opening above three thread for each bill printer, anti-leak-stopping list phenomenon, certainly, In
In others embodiment of the invention, above three thread also can be merged into less thread or be split as more threads, this
Invention does not limit this.Correspondingly, in this step, it the print out task is added to is beaten with target by queue thread of joining the team
In the corresponding printer task queue of print machine.Queue thread of joining the team each is beaten for intercepting for what target printer issued
Print task, and the print out task intercepted is added in printer task queue corresponding with target printer.Thus may be used
See, queue thread of joining the team is responsible for being added according to the print out task intercepted into the corresponding printer task queue of target printer
New print out task.Wherein, when printer task queue is the queue of first in first out, newest print out task is added to team
Arrange end.
Step S230: print out task is extracted from the corresponding printer task queue of target printer and is appointed as target
Business, and the print state of target printer is inquired, it, will be under goal task when the print state of target printer is available mode
It is sent to target printer.
Specifically, team's thread is gone out by queue and extracts printing times from the corresponding printer task queue of target printer
Business is used as goal task.When specific extraction, queuing time can be extracted according to the sequence of first in first out, and print out task is made earlier
For goal task.Alternatively, the weight of each print out task can also be obtained further combined with priority rule, it is higher to extract weight
Print out task, thus priority processing emergency task or vital task.When goal task is issued to target printer, pass through
The printing interface for calling printing SDK to provide, is encapsulated as the print command that printer can identify for goal task to be printed
Mode is issued.
In addition, in the present embodiment, queue goes out team's line in order to avoid causing to leak single phenomenon because target printer is unavailable
Journey inquires the print state of target printer, only when the print state of target printer is available mode, by goal task
It is issued to target printer.When it is implemented, for the ease of inquiring printer modes, the printer object of each bill printer
Internal further maintenance has available mode field, the available mode word for including in the printer object by inquiring target printer
The value of section can quickly determine the current state of target printer.
Further, in the present embodiment, further pass through the current state of state-detection thread polling targets printer,
The print state of target printer is updated according to polling result.Specifically, the corresponding detection interface of state-detection thread dispatching obtains
Take the current state of target printer:, can by include in printer object if the current state got is available mode
Available class value is set to the value of mode field；Conversely, then by the value for the available mode field for including in printer object
It is set to non-available class value.When specific detection, it can be detected according to the printing model of printer, for example, for network interface type
Printer, can be detected by the method for Ping IP address；For another example, for the printer of serial ports type, port can be passed through
Detection method is detected.When it is implemented, state-detection thread can be detected according to preset polling cycle every predetermined period
Printer modes, and judge whether to need the value of more new status field according to testing result.State-detection thread can also
With detection trigger process real-time after receiving abnormal state notification message, in order under abnormality detection immediately to the
One time detected abnormal restoring time point, so that it is guaranteed that the timely recovery of print out task.Wherein, abnormal state notification message can
Go out team's thread when printing abnormal by queue to trigger.Wherein, if the result that detection interface returns is that printer port is occupied,
The state of target printer is set to non-available mode by state-detection thread.Wherein, the occupied producing cause in port may be
Target printer is just occupied by other applications.The problem of can be avoided print out task time-out by this way or abandoning, Du
Single phenomenon is leaked absolutely.
In addition, queue goes out team's thread and passes through following two side when the print state of target printer is non-available mode
At least one of formula is handled, with prevent because printer modes it is unavailable caused by leak single phenomenon:
In the first processing mode, queue goes out the print state of team's thread polling targets printer, works as target printer
Print state when being switched to available mode, goal task is issued to target printer.Alternatively, can also be by state-detection line
Cheng Chixu detects the state of target printer, goes out team's thread to queue when the state that detects is available and sends a notification message, to mention
Show that queue goes out team's thread and issues goal task.Which time-out printing task can be issued when printer is unavailable, and to
Printer revert to it is available after issue print out task again, thus avoided from source because printer extremely caused by leakage list it is existing
As.
In second of processing mode, determines whether for goal task to be moved to according to the task priority of goal task and beat
Print state is in printer task queue corresponding to the bill printer of available mode.Specifically, when the task of goal task
It when priority is higher, needs to inquire the current state of each bill printer, is the bill printing of available mode from current state
The task queue not comprising emergency task or task negligible amounts is selected in printer task queue corresponding to machine, to will appoint
The business higher goal task of priority is inserted into the task queue of selection, to realize mutual between each bill printer
Coordinate.
In summary, in the present embodiment, each bill printer is provided with unique printer object in advance, and
And corresponding printer task queue is associated with by printer object, to ensure the orderly printing of each bill printer.And
And by the further association prints machine state of printer object, so as to issue print out task according to printer modes selection
Proper moment, anti-leak-stopping list phenomenon.It can be seen that since each bill printer possesses individual print queue, thus just
In the length and print out task robin manner that configure each print queue according to business demand mobilism.Also, due to every
Platform printer possesses joining the team, going out the operation such as team and print out task execution for different thread control print queues, it is thus possible to
Guarantee that will not influence other printers when separate unit printer failure normally executes print out task, improves system stability.Also,
The mode provided through the invention provides the print control scheme of complete set, appoints from automatically selecting to printing for printer
The automatic distribution of business can be automatically performed, so that only needing to consider business tine without closing when business side's assembly print data
Printed detail is infused, the operation cost of business side is simplified.
In addition, the implementation in the present embodiment is particularly suitable for scene of ordering.Wherein, ordering is a kind of meal point peak industry
Business scene, consumer orders in client barcode scanning plus dish, checkout, businessman leave consumption certificate, foreground printing in merchant end order
The receipts such as order/check and write off/reimbursement, rear kitchen print the receipts such as vegetable of preparing for a meal.Wherein, merchant end needs the base in traditional cash register software
Plug-in unit of ordering is installed, with function of ordering on Support Line on plinth.Since the bill printer of merchant end is multiple, thereby increases and it is possible to use string
Mouth, parallel port, network interface etc. instruct printing model, and therefore, plug-in unit of ordering may be with traditional cash register software when triggering print out task
The print out task of triggering carries out port and seizes, to cause leakage single.Since the business of ordering is in meal point, lower list quantity can reach moment
To wave crest, rather than the meal point period reaches trough again, thus be a huge test to the stability of printing link, meanwhile, by
Will lead in the diversity of lower single vegetable may need that multiple rear kitchen printers is called to be printed with a order, therefore, right
It also proposed high requirement in the selection of target printer.It can be seen that at least needing to overcome following in business scenario of ordering
Technical problem: first, meal point period can concurrent a large amount of business operation, thus concurrent a large amount of business datum, it is desirable to be able to
A large amount of business datum is received and processed simultaneously, and print out task corresponding to each business datum is quickly distributed to correspondence
Printer task queue in.Second, multiple different printers are corresponded respectively to since each business operation may trigger
Print out task, therefore, it is necessary to select matched target print from multiple bill printers automatically according to the type of business operation
Machine is printed.Technical solution in through the invention can effectively overcome above-mentioned technical problem.Also, the scheme in the present invention
Respectively be directed to each printer distribute task queue and monitoring print state by way of, can be avoided order plug-in unit and its
His application program seizes leakage list phenomenon caused by printer port.
