Abstract
A print unit prints by ejecting fluid droplets from a plurality of nozzles while moving in a primary scanning direction relative to a print medium. An ejection inspection unit inspects fluid droplet ejection by a group of target nozzles, which are part of an ejection nozzle subset obtained by dividing the nozzles according to the number of nozzles required to form the smallest printing width in the secondary scanning direction. A control unit controls the print unit and the ejection inspection unit, and selects the group of target nozzles in the ejection nozzle subset and performs the ejection inspection each time a specific amount of printing is completed.
