Abstract: At step S115, a printer control unit refers to a table using an average print duty as an input, and determines a saturation temperature and a drum preliminary heating temperature. In this example, since the saturation temperature and the preliminary heating temperature with respect to the print duty are stored as a table, the printer control unit refers to the table using the average print duty as the input, and determines the saturation temperature and the drum preliminary heating temperature. At step S120, the printer control unit investigates a current drum temperature based on a measurement result of a temperature sensor. Subsequently, at step S125, the drum is heated or cooled until it reaches, of the saturation temperature and the drum preliminary heating temperature, the temperature for which the difference with the current drum temperature is smaller.
