Abstract：The platform of integrated print in embedded system is designed and realized in this paper, as to ARM CPU and POS. At the same time hardware design theory and software driver are introduced also. In the integrated print, we explain the motor and pinhead besides of print core .Finally we give the every printing state.The stable running of POS’s printer remarks the correct and feasible design for hardware and the perfectible function for software.
