1. A printing control method for performing control of printing so as to feed a sheet to a printing unit, print an image on a first surface of the sheet, reverse the sheet for (i) a first surface and a second surface which is a back surface to the first surface of the sheet and (ii) a leading side of the sheet in a feed direction and a trailing side of the sheet in the feed direction, and print an image on the second surface in sequence, the printing control method comprising steps of:
acquiring information regarding ink application amounts to each of a plurality of different areas on a sheet trailing edge of the first surface, including at least a first area which covers a center portion of the sheet in a width direction crossing to the feed direction and a second area which covers one edge of the sheet in the width direction; assessing a plurality of candidate times including a time T1 which is assessed in accordance with a weighted combination of the ink application amount to the first area indicated by the information acquired by the acquiring step and the ink application amount to the second area indicated by the information acquired by the acquiring step; and determining a waiting time, for the control of the printing, until a start of printing on the second surface from an end of printing on the sheet trailing edge on the first surface based on the plurality of candidate times.
