Research And Development Of Drive Program Of High-resolution Inkjet Printer Based On ARM9

Along with the advance and development of economy and society, Consumers put forward new demands, such as product labeling, anti-counterfeiting technologies etc. At present, most of domestic inkjet printers base on MCU as drivers,connecting computer to unit into a system.The system has low efficiency, complicated structure. Therefore, the thesis proposes a high-resolution inkjet printer system which is based on ARM9 and WinCE5.0 OS-based systems.The system solves low speed and complex structure, enhances the stability of the system, reduces the costs of production and maintenance.The system is more suitable for promotion.It has good economic and social benefits.Driver is the core of inkjet printer system and driver is the key to drive hardware and operating system.Driver’s development is inseparable from hardware circuit, operating system and driver architecture.Firstly, the thesis researches domestic situation and development trend of inkjet printer. Secondly, the thesis introduces internal structure, principium of XJ128 nozzle and driver’s method in detail.Then, the thesis studies driven architecture of Windows CE, work mechanism and loading methods of driver. The thesis develops stream interface drivers which meet the logic of XJ128 nozzle, obey device manager and have standard interface.The stream interface drivers include SPI, PWM etc. Because driver must be controlled by application, so it has developed some applications to debug drivers.Finally, the drivers which are done debug in hardware circuit. It can print a plurality of pictures which are different sizes and shapes. Through repeated experiments, the drivers of high-resolution inkjet printer system can work stably and rapidly make response to fault,such as nozzle’s overheating, data transmission etc.The drivers can meet the printing requirements of the production process.At the end of thesis,it summarizes the problems and the experience which meet in the design work, and puts forward the prospect of system.
