Abstract
The ink jet printer is characterized by that its dynamic memory control module is respectively connected with the modules of clock, interface buffer, CPU, dynamic memory, step-by-step motor drive and ink-absorbing head data processing, etc. The clock module also is connected with the modules of crystal oscillator, interface buffer, CPU and step-by-step motor drive, and the interface buffer module is connected with PC parallel interface and CPU module, and the step-by-step motor drive module is connected with ink gun drive step-by-step motor, CPU module and paper advanced step-by-step motor, and the ink gun data processing module is connected with ink gun. Said invention can directly input printing data, so its circuit structure is simplified, cost is reduced and its practicability is strong and reliable.
Description
The present invention relates to a kind of printer, relate in particular to a kind of color inkjet printer.
Present color inkjet printer all is in computing machine data to be compressed earlier, and input printer in coding back is decompressed by printer and separates long-pending coding back and print, because operation is loaded down with trivial details, institute is so that complex structure, the manufacturing cost height.
The objective of the invention is to: design the machine that a kind of direct input print data is printed, save PC data compression, the process of coding back input printer, and decompress by printer again and separate long-pending coding back and print this step complicated procedures of forming.
The present invention is achieved in that it comprises clock module, dynamic memory module, and ink gun, ink gun drive step motor, the paper feed step motor, egress buffer module, CPU module, the dynamic storage control module, step motor driver module, ink gun data processing module, wherein the dynamic storage control module connects clock module respectively, the egress buffer module, CPU module, dynamic memory module, the step motor driver module, the ink gun data processing module; Clock module connects crystal oscillator, egress buffer module, CPU module, step motor driver module again respectively; The egress buffer module connects the PC parallel port respectively, the CPU module; The step motor driver module connects ink gun again respectively and drives step motor, CPU module, paper feed step motor; The ink gun data processing module connects ink gun.
The present invention has following advantage compared to existing technology: what dynamic storage received is the data of directly printing, and these data are not through overcompression and coding; Do not need hardware that the data of PC parallel port input are made an explanation, simplified circuit structure greatly and reduced hardware cost, and design concept is reasonable, practical reliable.
Below in conjunction with accompanying drawing the embodiment of the invention is further described:
Accompanying drawing is the block scheme that each module of the present invention connects.
As shown in the figure:
The CPU module receives PC parallel port input command, and order is made an explanation, and handles signals such as printer button, switch, sensor, also finishes functions such as self check.The dynamic storage control module is carried out read-write operation to dynamically depositing all device templates, and the data storage of the direct printing of PC parallel port input in dynamic memory module, give the ink ejection data processing module from the dynamic memory module output data then.The ink gun data processing module is converted into ink gun control data DATA to the print data that receives.Sending to ink gun by synchronous clock CLK again prints.The step motor driver module is finished the control that ink gun drives step motor and paper feed driving step motor.
Each functions of modules is: clock module is used to produce the required various clock signals of internal system and produces the system synchronization reset signal; The CPU module is used to receive control command that PC sends here and separates long-pending and handle printer button, switch and sensor signal; The dynamic storage control module is used to produce dynamic storage chip select, address and read-write and send the nozzle data processing module data of reading, dynamic memory module is used for directly storing PC and sends delegation's (multirow) two-way (unidirectional) print data here, these data need not CPU separate long-pending, direct print data; The step motor driver module is used to produce paper feed and ink gun drives step motor curve movement waveform and receives the dynamic storage data, and the step motor driver module is carried out initialization, can produce different curve movement waveforms; The egress buffer module is used for being connected with the standard parallel port of PC, receives the parallel port data.Data are carried out buffer memory.
