Design And Realize Of Wide Inkjet Printer With Low Cost Based On DSP

With the high differentiate technique improvement, real colour processing technique application, the new style ink design, the computer aided design and manufacturing development, the inkjet printer is applied more and more widely. Considering of the basic requirement of high differentiate, fast speed, printing in black and white, and low cost in printing cloth chart and engineering chart, it advances a breadth and high value low price inkjet print system based on DSP.Firstly, the hardware design part introduced the function module of inkjet printer, which includes the inkjet printer controller, data communication, data access, nozzle control, electromoter control about the paper movement system and nozzle movement system. It labors the major function and design requirement, Also it brought forward the viable realized method and described the design way of the controller programme.Secondly, the software design part introduces device program, which is based on Cypress EZ-USB FX2(CY68013A), EZ-USB driver, and application program. In device program part, the USB descriptor and endpoints descriptor are configured. The registers of control are setted up, and the data is receivded. In the USB driver part, the USB driver is modified for data transportation, and the INF file is also rewrited. In application program, the pagination arithmetic is given with high efficiency in the data pretreatment, the way of mapping and the Vector-Raster-Conversion arithmetic are supplied, the format of data stream is designed for more simple control.Through the test of the whole system, it shows the good performance in precision and speed, and with low cost, easy operation,high stability.
