ワイヤドツトプリンタ。[Claims for Utility Model Registration] (a) A piezoelectric element that detects an impact only when the printing wire returns to its origin; (b) A failure detection means that determines whether there is a malfunction based on the detection result; (c ) The failure detection means includes at least one of the following: the presence or absence of an output from the piezoelectric element at the time of returning to the origin, the time from the time when a driving voltage is applied to the time of returning to the origin, and the magnitude of the output voltage of the piezoelectric element at the time of returning to the origin. A wire dot printer characterized in that the printer compares the data with a standard state.
