The invention relates to a printing method through feedback and adjusting of capacitance and control of electrofluid. The printing method through feedback and adjusting of capacitance and control of electrofluid includes the steps: 1) through a capacitance detection module, detecting the capacitance between the stylus nozzle of an ink-holding ink-jet stylus and a printing substrate, and sending the capacitance data to a data processing module; 2) after the data processing module receives the capacitance data sent from the capacitance detection module, processing the capacitance data, and thensending the feedback data to a stylus nozzle voltage output control module after processing; and 3) after the stylus nozzle voltage output control module receives the feedback data sent from the dataprocessing module, adjusting the input voltage applied to the ink-holding ink-jet stylus. The invention also provides a printing apparatus through feedback and adjusting of capacitance and control ofelectrofluid utilizing the printing method through feedback and adjusting of capacitance and control of electrofluid. The printing method and apparatus through feedback and adjusting of capacitance and control of electrofluid enable the printed pattern to be uniform by detecting the real-time capacitance between the stylus nozzle and the printing substrate and then by adjusting the voltage appliedbetween the stylus nozzle and the printing substrate in real time to compensate the distance change between the stylus nozzle and the printing substrate. The printing method and apparatus through feedback and adjusting of capacitance and control of electrofluid belong to the technical field of ink-jet printing.
