Abstract
According to one embodiment, the label printer includes a light irradiation unit that irradiates an area illuminated by external light where a label on which printing is completed exists with light, a light irradiation control unit that switches between light irradiation and non-irradiation by the light irradiation unit, a light receiving unit that acquires an optical signal from the area where the label on which printing is completed exists in synchronization with the light irradiation and non-irradiation by the light irradiation control unit, and a label presence or absence determination unit that determines the presence or absence of a label based on a first signal acquired by the light-receiving unit if the light irradiation unit is not emitting light and a second signal acquired by the light receiving unit if the light irradiation unit is emitting light.
