This paper presents study of the Electrohydrodynamic Drop-an-Demand (DOD) phenomena by applying the multi-step pulse voltage. The multi-step voltage was generated through the high voltage power source connected with pulse generator. A DOD phenomenon was observed with the help of high speed camera. For study purpose the experiments were performed on ethanol by changing the operating parameters such as multi-step pulsed voltage, frequency of applied pulsed voltage and flow-rate. For DOD printing purpose conductive ink is used and patterns were made on the glass substrate and analyzed on different operating conditions. The minimum droplet diameter of approximately $40{mu}m$ at 325Hz frequency was achieved on the glass substrate. The printed pattern exhibited the linear ohmic behavior and pattern material is characterized through XRD. This study will help in better understanding of the Electrohydrodynamic DOD phenomena for the printing purpose.
