Abstract
An inkjet printing apparatus according to the present invention includes a first printing head that performs a first printing operation by discharging ink onto the printing medium, a second printing head positioned downstream from the first printing head in a transport direction and performing a second printing operation by discharging ink onto the printing medium, and a preliminary discharge controller that causes the second printing head to perform a preliminary discharging operation that does not contribute to the second printing operation, wherein the preliminary discharge controller causes an ink discharge amount of the preliminary discharging operation of the second printing head to be smaller when an ink discharge amount of the first printing operation is greater than or equal to a predetermined value than when the ink discharge amount of the first printing operation is less than the predetermined value.
