In the present embodiment, can according to printing model, number of print pages, time-write interval one of them or more than one of section come
The storage requirement (printing demand) is calculated, wherein the printing model includes colour print and/or black and white is printed.
It is illustrated below：
For example, communication unit 502 receives at least one print out task, the total page number of at least one print out task is N,
The number of pages of colour print is Nc in total page number N, and the number of pages of black and white printing is Nm, and total page number is N=Nc+Nm.
In the present embodiment, when calculating the storage requirement, it is contemplated that Multiple factors, such as printing model, type face
Number and time-write interval section, are calculated for example with formula (1)：
W=(Nc×a1+Nm×a2)×b (1)
In formula (1), a1And a2The coefficient that respectively colour print and black and white are printed；When b is predetermined printing
Between section coefficient.
In the case that print out task is colour, the coefficient calculated for storage requirement can be set to be higher than black and white
Situation, vice versa.For time-write interval section, time-write interval section can be set according to actual conditions by user and its be
Number, for example, the coefficient of working time section can be set as it is higher, by evening hours section coefficient be set as it is relatively low.
Fig. 6 is the coefficient schematic diagram calculated set by storage requirement of the embodiment of the present invention 2.
As shown in fig. 6, for the corresponding coefficient of printing model, setting a1More than a2, such as a1=1.5, a1More than a2=
1.0, vice versa；For time-write interval section coefficient b, in print out task more busy period, coefficient b can be set
Put big, and in other times section, relatively low, such as working time (8 can be set in such as non-working time section:00~
17:00) b, is set to 1.5；Section (17 on one's own time:00~24:00) 1.0 are set to, in inoperative
Between section (24:00~8:00) it is set to 0.5.
Setting in Fig. 6, for example, being 10 in the time-write interval:00, Nc=100 pages of colour print number of pages is black
In the case of white Nm=50 pages of number of print pages, storage requirement W is：W=[100 × 1.5+50 × 1.0] × 1.5=300.
The setting of above coefficient is not limited to above-described embodiment, can also be set, will not enumerate herein according to actual conditions；
In addition, above-mentioned working time section is divided into three periods, but be not limited to examples detailed above, also can by working time section according to
Need to be set to any section, and set coefficient for different time sections respectively, will not enumerate herein.
In above-mentioned formula (1), at the same consider number of print pages (can also be print data amount), printing model and
Time-write interval three factors of section, but the present embodiment not limited to this, can also be when calculating storage requirement W in consideration
State one or more of factors in factor.
In the present embodiment, the storage requirement can also be determined according to the printing model of print out task, i.e., according to this dozen
Watermark patterns are colour print or black and white printing to calculate；And the storage requirement is that colour is beaten in the print out task
It is bigger than when the print out task is black and white printing during print task.
For example, in the present embodiment, the storage requirement can be determined according to printing model and number of print pages, such as basis
The number of pages that the storage requirement can be printed using colour print and/or black and white is multiplied by pre-determined factor to determine, this makes a reservation for
Coefficient it is different for different printing models, the corresponding pre-determined factor of colour print higher than black and white print it is corresponding
Pre-determined factor.For example, can be calculated according to equation below (2)：
W=Nc×a1+Nm×a2 (2)
In formula (2), a1And a2The coefficient that respectively coefficient of colour print and black and white are printed, above-mentioned coefficient
It can be determined according to actual conditions, a1More than a2, vice versa.In the case of only colour print or black and white printing,
A can be made1Or a2Equal to 0.
In the present embodiment, the storage requirement can not also consider printing model, according only to number of print pages and time-write interval
Section is determined, for example, calculated according to equation below (3)：
W=N × b (3)
In formula (3), b is the coefficient of predetermined time-write interval section.
Foregoing illustrate the method calculated according to print out task storage requirement.But the invention is not restricted to this,
Storage requirement can also be calculated according to correlative factor is suitably considered the need for actual printing situation.
After storage requirement W is calculated, power control part 505 controls to store to the 1st according to the W calculated
The supply of electric power of the memory 5032 of device 5031 and the 2nd.
In the present embodiment, can be in the case where master control part 506 be judged as no memory demand, power control part
505 stop the supply of electric power to the 1st memory 5031 and the 2nd memory 5032, i.e. stop to the complete of storage part
Portion's memory is powered, and is transferred to battery saving mode and is handled.Wherein, according to the storage requirement W calculated,
No memory demand can be judged as when W is 0；Or can also be judged as when W is less than predetermined threshold W0
No memory demand.
Thereby, it is possible to being transferred directly to battery saving mode in the case of no memory demand, it is to avoid needed for memory
How many unnecessary judgements is asked, the resource of master control part 506 is saved.
In addition it is also possible in the case where master control part 506 is judged as no memory demand, and process stipulated time,
Power control part 505 stops the supply of electric power to the 1st memory 5031 and the 2nd memory 5032.
If stopping powering to the 1st and the 2nd memory immediately after no memory demand is judged as, in storage requirement
In the case of frequently occurring acute variation in a short time, power control part 505 can power to memory and power off it
Between shaken back and forth, thus easily to memory cause damage.In the present embodiment, it is being judged as that no memory need to
Ask and by just being stopped power supply in the case of the stipulated time, so, frequently occur violent change even in storage requirement
In the case of change, the concussion back and forth between power supply and power-off can be also avoided, thus, it is possible to reduce the damage to memory
Wound, extends the life-span of memory.
In addition, in the case where master control part 506 is judged as having storage requirement, can be according to the big of storage requirement
It is small, to control whether to power to the 1st memory 5031, the 2nd memory 5032.For example, can be by that will store
The comparative result that device demand W is compared with threshold value, to control to the 1st memory 5031, the 2nd memory 5032
Power supply.
For example, can be judged as having storage requirement in master control part 506 and storage requirement is more than the 1st threshold value
In the case of W1, memory controller 504 deposits the 1st memory 5031 and the 2nd to carry out the read-write of data
Reservoir 5032 is opened, and 505 pair of the 1st memory of power control part and the 2nd memory carry out supply of electric power.
It can also be judged as having storage requirement in master control part 506 and storage requirement is less than the 2nd threshold value W2's
In the case of, memory controller 504 opens the 1st memory 5031 to carry out the read-write of data, power supply control
505 pair of the 1st memory 5031 in portion processed carries out supply of electric power, and stops the supply of electric power to the 2nd memory 5032.
So, in the case of storage requirement is less so that 1 memory is in upstate, can save power consumption.
Above-mentioned 1st threshold value W1, the 2nd threshold value W2 can be preset, and may be configured as identical, may be alternatively provided as not
Together, further, it is also possible to be updated with the change of actual conditions.For example, in the present embodiment, storage part 503 has
There are 2 memories, the 1st threshold value W1 and the 2nd threshold value W2 can be set to identical.
