Abstract: An inkjet printing apparatus includes: an inkjet head including nozzles that discharge an ink; and a controller that controls to discharge the ink by the nozzles. The controller includes: a nozzle coordinate analyzer that analyzes coordinates of the nozzles based on a substrate; a nozzle selection probability grantor that assigns a nozzle selection probability the nozzles that how likely the nozzles are selected to discharge the ink; and an ink discharge determinator that determines whether to discharge the ink or not based on the nozzle selection probability.
