Embodiment
Carry out clear, complete description below with reference to accompanying drawing to the technical scheme of various embodiments of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the present invention protects.
Existing network printing method, each computing machine is according to the demand of real-time, print out task is carried out priority division respectively, and the print out task that preferential transmission priority is high, the network printer prints according to the print out task order received, the print out task priority that different computing machine is sent may be different, thus cause print out task that some computing machine priority are high and the low print out task of other computing machine priority to fight for network printer resource, reduce the printing effect of the high print out task of requirement of real-time; Further, each computing machine sends print out task according to the priority, do not alleviate the data volume being sent to the network printer, still can cause the technical matters that network blockage and network printer buffer memory overflow, and then cause network printer operational efficiency to decline, thus have impact on the printing effect of the high print out task of requirement of real-time further.
In the embodiment of the present invention, consider between the network printer and computing machine, set up a kind of communication-cooperation mechanism, by the network printer, the print out task received is managed, when print out task is comparatively busy, printing control information is sent to each computing machine, carry precedence information, each computing machine, after receiving printing control information, only sends the print out task higher than printing control information medium priority information to the network printer.Like this, the print out task priority that each computing machine sends is close, and the print out task avoiding priority high and the low print out task of priority fight for network printer resource, ensure that the printing effect of the print out task that requirement of real-time is high simultaneously.
Fig. 1 is the network printing method flow schematic diagram of the embodiment of the present invention.See Fig. 1, this flow process comprises:
Step 101, receives the print out task carrying precedence information that each computing machine sends, prints successively after storage according to reception order;
In this step, print successively according to reception order after storage and comprise:
In advance a print out task queue is set in the memory block of the network printer, and by print out task that each computing machine received sends, according to the principle of first-in first-out, leave in this print out task queue temporarily, then, network printer order reads the print out task in print out task queue, and performs printing.
Unlike the prior art, each computing machine, when sending print out task, also carries the precedence information of this print out task, controls the print out task that computing machine sends for the network printer of the present invention is follow-up.
Be the print out task to be printed received due to what show in the print out task queue of the network printer, therefore, the number of the print out task accumulated in print out task queue or data volume, reflect the relative capacity of the current execution print out task of the network printer.
Step 102, the print out task amount stored according to the time cycle statistics pre-set, when the print out task amount stored exceedes the threshold value pre-set, calculates the nominal priority value of the print out task stored;
In this step, print out task amount comprise print out task number and/or, data volume, corresponding, the threshold value pre-set comprises number threshold value and data-quantity threshold.If print out task amount exceedes the threshold value pre-set, show that in the network printer, unenforced print out task is more, the print out task quantity needing computer for controlling to send, to avoid the buffer memory of network blockage and the queue of storage networking printer print out task to overflow.
If print out task amount only includes print out task number, then judge whether the print out task number stored exceedes the number threshold value pre-set, if so, trigger the nominal priority value performing and calculate the print out task stored;
If print out task amount only includes print job data amount, then judge whether the print job data amount stored exceedes the data-quantity threshold pre-set, if so, trigger the nominal priority value performing and calculate the print out task stored;
If print out task amount comprises print out task number and data volume, then exceed the data-quantity threshold that pre-sets in the print job data amount stored and, when the print out task number stored exceedes the number threshold value pre-set, trigger the nominal priority value performing and calculate the print out task stored, otherwise, do not deal with.
In the embodiment of the present invention, by arranging monitoring modular on the network printer, print out task number in print out task queue on the periodic monitor network printer and/or, data volume, when print out task number and/or, when data volume reaches the threshold value pre-set, start and calculate, to control the print out task that subsequent calculations machine sends printing the nominal priority of each print out task in task queue.
The nominal priority value calculating the print out task stored can be:
A01, obtains the priority value of each print out task stored;
A02, calculate the priority value of each print out task and, be divided by with print out task number, obtain nominal priority value.
In this step, if the priority value of print out task j is A
j, then the computing formula of nominal priority value is:
In formula,
Γ is nominal priority value;
M is print out task number.
Certainly, in practical application, other modes also can be adopted to calculate nominal priority value, and the nominal priority value namely calculating the print out task of storage also can be:
A11, pre-sets the priority factors that each priority value is corresponding, and the priority factors sum that each priority value is corresponding is 1;
In this step, such as, for the priority value being according to priority just sequentially 5,4,3,2,1, the priority factors that can arrange priority value 5 and 4 corresponding is respectively 0.3, the priority factors of priority value 3 correspondence is 0.2, and the priority factors that priority value 2 and 1 is corresponding is respectively 0.1.Certainly, other priority factors that each priority value is corresponding also can be set, as long as priority factors sum corresponding to each priority value is 1.
Priority factors corresponding for each priority value is normalized, by itself and be set to 1, be the convenience considering subsequent calculations.
In this step, setting priority value A
icorresponding priority factors is ξ
i, then:
In formula, k is priority level number.
A12, obtains the priority value of each print out task stored, calculates each priority value and the product of corresponding priority factors, then sue for peace, obtain nominal priority value summation;
In this step, the computing formula of nominal priority value summation is:
In formula,
Φ is nominal priority value summation.
A13, calculates the priority factors sum that the priority value of each print out task is corresponding, obtains nominal priority factors summation;
In this step, nominal priority factors summation computing formula is:
In formula,
ψ is nominal priority factors summation;
ξ
jfor the priority value A of print out task j
jcorresponding priority factors.
A14, calculates the ratio of nominal priority value summation and nominal priority factors summation, as nominal priority value.
In this step, nominal priority value Γ computing formula is:
Preferably, the method also comprises:
When the print out task amount stored does not exceed the threshold value pre-set, continue to wait for that the next time cycle carries out adding up the flow process of the print out task amount stored.
In practical application, be not the situation of integer for the nominal priority value calculated, can carry out rounding process.
Step 103, sends printing control information to each computing machine, carries nominal priority value information, sends to make each computing machine of reception printing control information the print out task being not less than nominal priority value to the network printer.
In this step, the each computing machine be connected with the network printer in LAN (Local Area Network) is after receiving the printing control information that the network printer sends, within the ensuing time cycle, change the strategy sending print out task, start filtering transmissions mechanism, only send the print out task higher than nominal priority value to the network printer, and after sending the print out task higher than nominal priority value, no longer send the print out task that other do not send, to reduce the bandwidth resources of transfer printing task, avoid overflowing of network printer buffer memory.Namely the print out task that computing machine is not less than nominal priority value to network printer transmission comprises:
Within the time cycle pre-set, computing machine judges one by one to the print out task in this side print out task queue, if the priority value of this print out task is not less than described nominal priority value, then send this print out task, otherwise, skip this print out task, proceed the judgement of next print out task.That is, priority value is not less than to the print out task of nominal priority value, normally sends to the network printer, for the print out task of priority value lower than nominal priority value, skip and wouldn't send, and judge whether next print out task can normally send.
In practical application, computing machine, when receiving printing control information, may exist in upper a period of time, and the nominal priority value information of carrying in the printing control information received according to upper sends, the print out task do not sent in addition.Like this, printing control information is being sent to each computing machine, after carrying the step of nominal priority value information, with make each computing machine of reception printing control information to the network printer send be not less than the step of the print out task of nominal priority value before, comprise further:
Computing machine receives printing control information, judges whether current transmission is in idle condition:
If so, the print out task being not less than nominal priority value to network printer transmission is performed;
If not, judge whether the nominal priority value carried in the printing control information received is not less than in a printing control information the nominal priority value carried, if, again print out task queue is traveled through, perform and send to the network printer print out task being not less than in the printing control information of current reception the nominal priority value carried, if not, continue the queue of traversal print out task, the nominal priority value information of carrying in the printing control information received according to upper sends, after being sent, again print out task queue is traveled through, perform and send to the network printer print out task being not less than in the printing control information of current reception the nominal priority value carried.
In this step, if computing machine is within the time cycle pre-set, the print out task being not less than described nominal priority value in print out task queue is sent, then represents that current transmission is in idle condition.
When current transmission is not in idle condition, if current nominal priority value (the nominal priority value carried in the printing control information of current reception) is not less than a nominal priority value, show that network printing pusher side print out task amount is more, also need the print out task amount suitably reducing computer-side transmission, then computing machine stops sending according to a upper nominal priority value information, adopt more strict sending strategy, again start anew scanning and printing task queue, and send the print out task being not less than current nominal priority value to the network printer; And if current nominal priority value is less than a nominal priority value, show that network printing pusher side print out task amount is less, suitably can increase the print out task amount that computer-side sends, then computing machine is in order to ensure that the print out task of high priority preferentially sends, continue the remaining print out task queue of scanning, and send print out task according to a upper nominal priority value information, after being sent, again travel through print out task queue again, send the print out task being not less than current nominal priority value to the network printer.
Preferably, the method can further include:
The time cycle pre-set then, if computing machine do not receive the network printer send printing control information, sequentially send the print out task in this side print out task queue.
In this step, if computing machine the time cycle pre-set then, also do not receive the printing control information that the network printer sends, show in the print out task queue of the network printer, there is no too many print out task, unenforced print out task is less, then above-mentioned filtering type transmission print out task can be reverted to and send print out task in the normal order.
From above-mentioned, the network printing method of the embodiment of the present invention, by the print out task amount stored according to the time cycle statistics pre-set, when the print out task amount stored exceedes the threshold value pre-set, calculates the nominal priority value of the print out task stored; And sending nominal priority value information to each computing machine, computer for controlling sends the print out task being not less than the nominal priority value of reception to the network printer.Like this, computing machine is after sending the print out task higher than nominal priority value, no longer send the print out task that other do not send, effectively can reduce the bandwidth resources of transfer printing task, avoid and continue to send the network blockage that causes of print out task, decrease the spatial cache that the network printer carries out needed for buffer memory, simultaneously, print out task is sent according to the nominal priority value received by each computing machine, like this, if the print out task number of high priority is less in computing machine, the print out task number sent is also less, if and the print out task number of high priority is more in computing machine, the print out task number then sent is also more, avoid in each computing machine because the print out task number of different priorities is different, each computing machine is made to be sent to the print out task of the network printer by the priority of existing print out task, its priority may differ larger, the phenomenon that the print out task needs causing priority high and the low print out task of priority fight for network printer resource occurs, the priority of the print out task that the network printer is received is all higher, ensure that the printing effect of the print out task that requirement of real-time is high.
Below again from network printing pusher side and computer-side, the network printing method of the embodiment of the present invention is described in detail.
Fig. 2 is the method flow schematic diagram that embodiment of the present invention network printing pusher side realizes network printing.See Fig. 2, this flow process comprises:
Step 201, the print out task number in the queue of network printer periodic statistical print out task, compares with the threshold value preset;
In this step, regularly refer to the time cycle of setting, default threshold value is number threshold value.
In print out task queue, if print out task is printed, then automatically deleted from print out task queue by this print out task, thus, the print out task in print out task queue is all the print out task of untreated (printing).
Step 202, judges the threshold value whether print out task number reaches default, if so, performs step 203, otherwise, return and perform step 201;
This step for each computing machine of controlling to be connected with the network printer the need of the print out task number slowing down transmission.
Step 203, the network printer extracts the priority value of each print out task in print out task queue, calculates average priority value, sends it to computing machine.
In this step, adopt the method for average computation, using the average priority value that calculates as nominal priority value.
After average priority value is sent to each computing machine, return and perform step 201, so circulate, until the announcement information that the print out task receiving the transmission of each computing machine has been sent, terminate the flow process of this network printing.
Fig. 3 is the method flow schematic diagram that embodiment of the present invention computer-side realizes network printing.See Fig. 3, this flow process comprises:
Step 301, computing machine regularly judges whether the average priority value information receiving network printer transmission, if so, performs step 302, otherwise, perform step 303;
In this step, computing machine needs, according to the average priority value information received, to adjust current sending strategy.
Step 302, computing machine, according to the sequencing of print out task in print out task queue, sends print out task to the network printer one by one;
In this step, in computing machine, be provided with print out task queue, for the buffer memory print out task carrying out printing to the network printer to be sent.
Continue send print out task a period of time, the time cycle pre-set then, return perform step 301.
Step 303, computing machine reads the priority value of first bar print out task in print out task queue;
Step 304, judges that whether the priority value of this print out task is higher than average priority value, if so, performs step 305, otherwise, perform step 306;
In this step, the priority value of print out task is higher, shows that its priority level is higher, needs priority processing.
Step 305, sends first bar print out task to the network printer, after being sent, performs step 307;
Step 306, skips this first bar print out task, performs step 307;
Step 307, reads the priority value of next print out task, returns and performs step 304.
Lift a specific embodiment below, then the invention will be further described.
Embodiment:
Suppose that certain network printer is once monitored the print out task queue of self for every 5 minutes, the network printer at a time finds during printing task queue monitoring, print out task number to be printed is 76, higher than the threshold value 50 preset, so extract the priority value of each bar print out task in print out task queue, be averaged calculating, and obtaining average priority value result is 3, sends to each computing machine in LAN (Local Area Network) after this result of calculation being encapsulated.
Fig. 4 is certain computing machine self print out task queue schematic diagram before receiving result of calculation.As shown in Figure 4, the some time of this computing machine before receiving result of calculation is carved with a print out task and sends messaging list (print out task queue), comprising: reference number of a document hurdle (print out task numbering), file-level hurdle (print out task priority value), submission time hurdle, folio column and status bar.Such as, be the print out task of 401326167 for reference number of a document, file-level is 5, when submission time is 14 days 9 May in 2012 26 points, and number of pages is 12 pages, state is in transmission, in print out task queue, only have the state of a print out task in transmission, the state of all the other print out task is wait.Under normal circumstances, this computing machine is by the order according to print out task queue, each bar print out task is sent to the network printer one by one, namely sequence number be 401326167 Article 1 print out task be sent out away after, namely this print out task record disappears in print out task queue, then send next print out task, namely sequence number is the print out task of 401326168, and the new print out task produced then constantly sequentially is added on after print out task queue.
In the embodiment of the present invention, before the Article 1 print out task that to suppose in sequence number be 401326167 is sent to the network printer, computing machine have received the printing control information of carrying nominal precedence information that the network printer sends, wherein, name priority value (average priority value) is 3, then trigger computer starting and filter transmit mechanism, namely when order sends each print out task, first the nominal priority value that the priority value of this print out task and the network printer send is compared, for the print out task of the nominal priority value that priority value sends lower than the network printer, temporarily do not send, jump to next print out task to judge, priority value is not less than to the print out task of the nominal priority value that the network printer sends, at once send after having judged.
Fig. 5 is print out task queue schematic diagram after embodiment of the present invention execution filtration transmit mechanism a period of time.See Fig. 5, can find out, the priority value being two print out task of 401326167,401326168 due to reference number of a document is respectively 5 and 4, is not less than the nominal priority value 3 that the network printer sends, therefore sent one by one, thus disappeared in print out task queue; But for three print out task that reference number of a document is 401326169,401326170,401326171, because its priority value is respectively 1,2,2, lower than the nominal priority value 3 that the network printer sends, therefore all " skipped ", thus being temporarily retained in print out task queue, current file number is the print out task of 401326172, and its priority value is 3, be not less than the nominal priority value 3 that the network printer sends, be in state in transmission.
Because other computing machine be connected with the network printer also sends print out task according to above-mentioned filtration transmit mechanism, therefore, within the time cycle pre-set, the print out task of low priority value is all persisted in the print out task queue of each computing machine, and the print out task that the network printer receives, its priority value all more than 3, like this, when ensure that network printer print capacity relative deficiency, the ticket printing task that preferential printing priority is high.
In this case, suppose that the priority value of the print out task that the computing machine had produces during the time cycle of this setting is all lower than 3, then the print out task that this computing machine produces all cannot send; Suppose that the priority value of the print out task that the computing machine had produces during the time cycle of this setting is all not less than 3, then every bar print out task that this computing machine produces all can sequentially send.That is, network printing method of the present invention, in transmission print out task, breach relatively isolating between computing machine, make between each computing machine, by the network printer, dynamically can coordinate to use network printer resource, thus achieve the optimum efficiency that print out task plans as a whole printing over the entire network.
Suppose that the time cycle arranged is 5 minutes, then sent printing control information to each computing machine 5 minutes after (second 5 minutes) in last time, the number of print out task to print out task in row checked again by the network printer, if the number of print out task is still not less than predetermined threshold value, then again calculate the now print out task average priority value to print out task in row, obtaining average priority value is 4, these data are carried in printing control information, send to each computing machine, each computing machine continues to perform strobe utility; Continue perform strobe utility time, preferably, from print out task to row in first bar print out task priority value compare, with aforementioned unlike, compare with new average priority value 4, other is constant.
As can be seen from above-described embodiment, at first in 5 minutes, due to network printer print capacity relative deficiency, it is 3 that each computing machine temporarily only sends priority value, 4, the print out task of 5, but even so, after 5 minutes, network printing pusher side still have accumulated the print out task number exceeding threshold value, objectively also need the strobe utility standard improving computer-side further, and the network printer print out task now average priority value to each print out task in row also reflects and needs to improve strobe utility standard, thus, the average priority value sent to each computing machine is updated to 4, send average data again, after each computing machine receives new average priority value, in ensuing 5 minutes, namely second in 5 minutes, strobe utility standard is brought up to and has been not less than 4, only send the print out task that priority value is 4 and 5, that is, use network printing method of the present invention, the degree of network printer executive capability relative deficiency, determine the priority height that computing machine sends print out task, enable to carry out dynamic Adaptive matching, and control more accurate.
Suppose and spent 5 minutes (the 3rd 5 minutes), the number of print out task to print out task in row checked again by the network printer, if the total number of print out task is 16, lower than predetermined threshold value 50, then not execution priority value mean value calculation and transmission, each computing machine is after second 5 minute time limit arrives, if do not receive the printing control information that the network printer sends, so automatically revert to normal transmission, namely print out task to row in, print out task is sent successively according to putting in order, comprise those print out task temporarily skipped when original filtration sends.In the embodiment of the present invention, after computing machine receives printing control information at every turn, run time of continuing of strobe utility and the network printer and check that the monitoring periods of print out task to the number of print out task in arranging is consistent.
Compared with prior art, the present invention passes through monitoring network printer print out task to the print out task number in row, and then judges the relation between the current print capacity of the network printer and printing demand, and namely print capacity meets the degree of printing demand, due to network printer print out task to row in print out task from each computing machine, therefore, this print out task is to the average priority value of print out task in row, reflection be the comprehensive condition of all computer printout tasks in whole LAN system in the nearest time period, therefore, this parameter (average priority value) is sent to each computing machine, in each computing machine subsequent time period, the filter criteria of print out task transmission is controlled using it, what realize is a coordinated balance in whole LAN system between all computing machines, ensure be the network printer print capacity relative deficiency time, the print out task that whole LAN system medium priority is high can obtain printing the most timely, and can control accurately.
