Before a printing operation, printing conditions related to occurrence of mist are acquired. According to the printing conditions, mist reduction device and a mist-reduction correction amount for controlling a degree of reducing the mist by the mist reduction device are set. Thereafter, printing is performed on a print medium by use of the set mist-reduction correction amount and mist reduction device. Accordingly, an appropriate mist reduction method is adopted according to the various printing conditions. Thus, optimum printing can be executed without impairing image quality or user-friendliness more than necessary.
