Method for controlling transportation of print medium in inkjet printing apparatus and the inkjet printing apparatus

Web paper is transported by roll with two or more drive rollers. The two adjacent drive rollers each have difference in rotation speed in accordance with a draw ratio. Accordingly, tension is applied to the web paper. Tension of the web paper between the adjacent drive rollers is detected by a tension sensor. A tension controller controls the detected tension value so as to be a target tension value. A predictive control device predicts decrease in tension during an initial printing period where tension control is not stable, and increases rotation speeds of the drive rollers downstream of a print unit to suppress the decrease in tension. Consequently, tension acting on the web paper is appropriately controlled also during the initial printing period, resulting in possible reduction in printing quality.
