A printing device has a detecting section in which a light emitting section and a light receiving section are provided, liquid reservoirs for storing liquid in which a prism is provided to reflect light emitted from the light emitting section corresponding to a remaining state of the liquid, and a control section. The control section determines whether a process for air bubbles that is a process corresponding to an adhesion state of air bubbles in the prism is to be conducted or not based on a signal of light reception results obtained by receiving reflected light from the prism by the light receiving section.
