A printer or the like is provided that can increase adhesiveness between cured photo curable ink and a print medium as necessary. The printer includes a discharge unit 8 that discharges UV ink on a print medium S, an ultraviolet ray irradiation unit 15 that is set to a first mode in which, of a first light for curing the UV ink and a second light with higher curing properties than the first light, only the first light is irradiated on the print medium S on which the UV ink has been discharged, or a second mode in which at least the second light is irradiated, an adhesiveness information acquisition unit that acquires adhesiveness information related to ink adhesiveness which is adhesiveness between the UV ink and the print medium S when the UV ink is cured using the first light, and a control unit that sets the ultraviolet ray irradiation unit 15 to the second mode when the acquired adhesiveness information is designated information related to low ink adhesiveness.
