Abstract
A print buffer for storing recording data is divided into a plurality of segments and the amount of recording data causing a recording head to perform a recording operation is counted on a segment-by-segment basis. A recording medium is compared to the print buffer with respect to a scanning direction of the recording head and segments not corresponding to the inside of the recording medium are selected from the plurality of segments. The amount of recording data included in the selected segments and causing a recording operation to occur is counted and added up to estimate the amount of ink ejected outside the recording medium.
