ABSTRACT:
In a printing apparatus comprising a first conveyance system (C1) for conveying a first printing medium (3), a second conveyance system (C2) for conveying a second printing medium (6), and a print head (1) for conducting printing on the first or second printing medium on a platen (2), a detector (13) detects presence or absence of the first printing medium on the first conveyance system (C1), and a platen drive controller (18) causes rotation of the platen during the printing or conveyance of the second printing medium if the first printing medium is found present in the first conveyance system (C1). The platen drive controller may conduct the control over the rotation also on the basis of the state of conveyance of the second printing medium in order to ensure rotation of the platen from time to time while avoiding excessive rotation to reduce noises and power consumption.
