Temperature characteristic information of each line of a print image is established in a database, an initial value of a temperature sensor is corrected such that a difference between a temperature measured by the temperature sensor provided in a print head and a temperature estimated on the basis of the temperature characteristic information established in the database is in an allowable range, and a printing operation is performed according to the temperature measured by the corrected temperature sensor. Accordingly, it is possible to prevent printing quality from deteriorating due to a measurement error of the temperature sensor.
