Abstract: In the case where a preliminary discharge operation is always performed at a position that is spaced apart from a recording area, the time taken for a recording head to be moved to a preliminary discharge position is increased, and this results in a decrease in throughput. In the case where it is determined that a leading end or a trailing end of a recording medium is located on a platen, positions at which the distance from an end of a recording medium to a recording head with respect to a moving direction is not smaller than a threshold are determined as preliminary discharge positions, and the recording head is controlled to perform a preliminary discharge operation.
