A printer apparatus includes a medium supporter to support a printing medium. A carriage holds a printer head provided with a nozzle from which ink is to be ejected onto a printing surface of the printing medium. A carriage moving mechanism moves the carriage along the printing surface of the printing medium supported by the medium supporter. An acceleration detector is configured to detect acceleration of vibration generated in the carriage. A determining device is configured to determine whether a magnitude of the acceleration detected by the acceleration detector exceeds a predetermined threshold value. A controller is configured to control the carriage moving mechanism to restrict relative movement of the carriage when the determining device determines that the magnitude of the acceleration detected by the acceleration detector exceeds the predetermined threshold value.
