Abstract
An ink dot printer comprising an opposite electrode, a carriage capable of reciprocating along the opposite electrode, a printing head mounted on the carriage, recording electrodes arranged within the printing head so that the tips thereof can be exposed through openings formed in a wall of the printing head opposite the opposite electrode, and a cap supported moveably on either the carriage or the printing head so as to close or open the openings of the printing head. When the ink dot printer is not in printing operation, the cap is closed to cover up the tips of the recording electrodes to prevent the drying of the tips of the recording electrode due to the evaporation of the ink so that the recording electrodes are always in good condition for stable printing operation.
