ABSTRACT:
An ink-jet printer has a print head that performs printing on a print medium transported in a print medium transport direction by scanning in a scanning direction intersecting the print medium transport direction. A platen supports the print medium while the print medium is transported along the print medium transport direction. The platen has heater blocks that become smaller in width in the scanning direction toward both ends of the platen. A measurement section measures a surface temperature of each of portions of the print medium supported by the platen. A calculation section calculates an output value of each of the heater blocks for making the surface temperature of each of the portions of the print medium uniform based on the surface temperature measured by the measurement section. A heater temperature control section controls an output of each of the heater blocks based on the output value calculated by the calculation section.
