In the current-carrying type printer, the resistance layer generates heat by passing a corresponding electric current, and the heat generated melts or sublimates the ink of the ink film to record dots on the paper. 1. A current-carrying type printer, comprising means for inspecting the characteristics of a current path between the electrode and the return electrode. (2) The current-carrying type printer according to claim 1, further comprising means for determining when to repair or replace the head based on the inspection result of the inspection means. (3) The current-carrying type printer according to claim 1 or 2, further comprising means for displaying the inspection result of the inspection means or the judgment result of the judgment means.
