Abstract: There is disclosed herein a dot matrix tilting print head assembly in which the print head is rotatably mounted in frame means. Solenoid means are provided for rotating the print head a controlled distance so that printing occurs between previously printed dots. Means are provided for controlling the distance to be one half of the center-to-center distance between printed dots. This entails maintaining very low tolerances for the mechanically moving parts. In addition, there is provided means for removing the print head alone from the frame means. BC9-79-018
