An output value of the transport position output portion when a first mark which is provided in a recording medium is at a predetermined position with respect to a detection region is stored in a storage portion as a reference value, and a start timing of the printing of the image is controlled based on the timing at which the mark detection portion detects the mark after confirming that the first mark reaches a predetermined range from the detection region based on comparison of the output value of the transport position output portion and the reference value with each other, when the transport in the first direction of the recording medium is started.
