Disclosed is a printing device including at least one processor and a print head. The processor detects a nail region based on an image obtained by photographing a finger or a toe, sets at least a part of the detected nail region as a preceding print setting region, detects a region on which the preceding print is printed as a succeeding print region based on an image obtained by photographing the finger or the toe on which the preceding print is printed, sets a succeeding print region reference point corresponding to the succeeding print region, or sets a preceding print setting region reference point corresponding to the preceding print setting region and the succeeding print region reference point, and causes the print head to print a succeeding print on the nail region based on information on the preceding print setting region and a reference point that is set.
