摘要： A printing apparatus including a platen unit including a platen surface on which a medium is disposed; a carriage including a print head and a sonic sensor, the carriage being configured to move; and a flat surface unit including a plurality of flat surfaces disposed such that distances between the sonic sensor and the plurality of flat surfaces are different from each other. The printing apparatus derives a relational expression from a surface-by-surface distance difference among the flat surfaces of the flat surface unit and a transmission/reception time to and from each surface, obtained based on a measurement by the sonic sensor, and determines, from the relational expression and the transmission/reception time measured at the medium, a distance to the medium.

摘要： A recording apparatus is provided with a droplet discharging head having a nozzle forming portion and a charging unit. The nozzle forming portion includes nozzles formed therein. The charging unit is configured to impart an electrical charge to the medium. The charging unit imparts, to the medium, an electrical charge having the same polarity as an electrically charged state of the nozzle forming portion after the droplets are discharged.
