Abstract: In order to solve the problem of control environment and cost caused by the extra nozzle control module in the spray printing industry, the spray printing technology was applied to the other industries such as medical which has higher requirements for the control environment. After the investigation and summary of the properties and prices of Cortex M3 series microprocessor, and after a brief analysis of the pin and data transmission of XJ128 nozzle, a XJ128 nozzle`s drive system based on ARM Cortex M3 core was designed, the XJ128 nozzle was drove directly by ARM Cortex M3 LPC1752 Development Board. The results of research and experiments indicate that the control system can meet the requirement of the XJ128 nozzle, and the system not only can drive the nozzle to eject on demand but also have a high stability at a high speed during a long time.
