Abstract
An ink jet printing apparatus is provided which can prevent a discharged paper-induced smear efficiently with a simple construction. To achieve this objective, the ink jet printing apparatus of this invention determines, based on an amount of ink ejected per unit area onto a preceding print medium last discharged to the discharge position by the discharging section, a required time duration that needs to elapse before a subsequent print medium being discharged toward the discharge position is allowed to contact a predetermined area of the preceding print medium and then controls a printing speed on the subsequent print medium so that the subsequent print medium will not contact the predetermined area of the preceding print medium within the time duration determined.
