A method for managing motor components is performed such that, while one of the motor components is held, identifying information, such as a two-dimensional code, for example, is printed on a printable region on a metal surface of the motor component by discharging ink from a printing head toward the printable region and relatively displacing a position at which the ink reaches within the printable region by moving one of the motor component and the printing head relative to the other. Then, the identifying information on the motor component is read. The identifying information that has been read is stored for each of the motor components. Based on the stored identifying information, the motor components are managed.
