The specific embodiment
Print control unit according to the utility model embodiment comprises master control borad and carrier frame plate, and wherein, carrier frame plate is used for receiving from the pretreated print data of subscriber computer, and these data are handled once more.Carrier frame plate can specifically comprise second interface unit, data processing unit, memory cell, auxiliary and sensing unit and shower nozzle driver element.Wherein, second interface unit is used to receive the pretreated print data of described print software, memory cell is used for the data that second interface unit receives are stored, data processing unit is used for taking out data from memory cell to be handled once more, and the data-driven shower nozzle after the shower nozzle driver element is used for handling once more according to described data processing unit prints.Master control borad can specifically comprise first interface unit, control module, carriage servo drive unit, media drive unit and auxiliary and sensing unit.Wherein, first interface unit is used to receive the instruction from subscriber computer, and control module is used for controlling according to described instruction.
According to the print system of the utility model embodiment, comprise subscriber computer and aforesaid print control unit, print software is installed on the subscriber computer, be used for print data is carried out preliminary treatment.
As shown in Figure 2, the print system according to the utility model embodiment comprises subscriber computer 210 and print control unit 238.Wherein, on the subscriber computer 210 print software is housed, is used for print data is carried out preliminary treatment.Print control unit 238 comprises master control borad 212 and carrier frame plate 226.Master control borad 212 comprises first interface unit 214, control module 216, carriage servo drive unit 218, media drive unit 220, auxiliary and sensing unit 222 again.Alternatively, master control borad 212 can also comprise human-computer interaction interface 224.Human-computer interaction interface 224 can be made up of display and keyboard, finishes to show and input function.
Carriage servo drive unit 218 is used to finish the driving to servomotor, makes carrier frame plate finish various motions, for example, and the scanning motion on the horizontal direction when detecting medium width and operate as normal etc.Media drive unit 220 is used to drive stepper motor, and print media is moved in vertical direction.The auxiliary sensing unit 222 that reaches is used to finish some auxiliary and sensing functions, and for example, shower nozzle flushing, negative pressure exhausting, drying, medium back-up system, medium be loading, media location and width detection etc. automatically.
Print system workflow according to the utility model embodiment is as follows:
Step 1, subscriber computer 210 print the preliminary treatment of data.
At first, the image processing software on the subscriber computer 210, RIP (raster image processor, Raster Image Processor) software for example, (TIF JPG), is converted to the raster data that meets printer resolution with the continuous images file.
Then, the print software on the subscriber computer 210 is handled raster data.
Print software receives data from image processing software.Receiving data can have dual mode, is example with RIP software: (1) is read RIP software and is printed the RIP file that finishes; (2) get in touch with the foundation of RIP software, data are directly sent in the print software by port.
After receiving data, the data processing module of print software is resolved raster data, is processed into the commentaries on classics order data of printer identification, and the print zone border of definite carrier frame plate.Print zone is the scope of valid data, comprises the initial sum rest position of valid data.Carrier frame plate will be monitored motor and whether enter this scope, as enter, and then start ink according to data and spray, and print appointed pattern.Can determine the print zone border according to the width of image.When concrete the processing, consider the relativity shift of each shower nozzle, and the two-way skew of printing, should be offset data accordingly.
Simultaneously, the motor movement parameter determination module of print software is determined motor movement parameters such as motor displacement according to the width and the affix acceleration and deceleration district of valid data.
Print software can also have other miscellaneous function.For example, printer calibration.The printer calibration comprises longitudinal alignment, horizontal calibration, two-way calibration and step calibration, is mainly used in and adjusts printer to optimum state.Again for example, human-computer interaction interface can be set also on print software, realize the printer modes monitoring, be mainly the parameter adjustment operation of response user on the man-machine interface 224 of master control borad 212, start test printing etc. by this human-computer interaction interface.When the user after man-machine interface 224 has carried out an operation, printer sends a message by modes such as serial ports to software immediately, software promptly responds this message, the update software state after receiving corresponding message.If having carried out operation, software can notify printer too, to guarantee unanimity between the two.Therefore, human-computer interaction interface is set on master control borad, simultaneously the printer modes monitoring function is set on print software again, make the user both can be from the enterprising line operate of subscriber computer, again can be from the enterprising line operate of master control borad.The operation of user on the human-computer interaction interface of printer can be updated on the print software at once, printer shutdown back equipment state can be kept on the subscriber computer, and the operation of print software also can be updated on the human-computer interaction interface at once, very convenient user's use, thus user's impression strengthened.
Step 2, carrier frame plate receive pretreated data, handle once more, and print according to the Data Control shower nozzle of handling once more.
After the pretreated data of subscriber computer are received by second interface unit 228, enter the push-up storage (FIFO) of data processing unit 230 inside, under the control of the control module of data processing unit 230 inside, deposit memory cell 232 in then.Afterwards, under the triggering of grating, data processing unit 230 takes out data from memory cell 232, after handling once more through ordering, control command extraction, distribution, parallel/serial conversion etc., according to specific sequential requirement, sends to shower nozzle, and the ink-jet of control shower nozzle.
Step 3, master control borad 212 control carrier frame plates carry out horizontal movement, and the control print media is in vertical motion.Finally, by the ink-jet of shower nozzle and the motion of carrier frame plate and print media, output image on medium.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, this program can be stored in the computer read/write memory medium, as: ROM/RAM, magnetic disc, CD etc.
Though will also be appreciated that in the above-mentioned explanation, for ease of understanding, the step of method has been taked the succession description, should be pointed out that the order of above-mentioned steps is not done strict restriction.
Will also be appreciated that the apparatus structure shown in accompanying drawing or the embodiment only is schematically, the presentation logic structure.Wherein the module that shows as separating component may or may not be physically to separate, and the parts that show as module may be or may not be physical modules, both can be positioned at a place, also can be distributed on the plurality of units.
According to the utility model embodiment, a large amount of, complex image data processing task that former cause master control borad is born are decomposed into two parts, a part is by subscriber computer, especially the print software on the subscriber computer, finish, another part is by carrier frame plate, and especially the data processing unit on the carrier frame plate is finished.Like this, both made full use of the high-speed parallel characteristic of subscriber computer powerful computing ability and data processing unit (for example FPGA), finished the complex image data processing task, make the printer master control borad no longer need built-in powerful CPU again, significantly lowered the complexity and the cost of master control borad, thereby the cost of whole system is reduced greatly.
