Abstract
A rounded end on a pivoted arm impacts a print medium through an ink ribbon to form a printed dot on the print medium. For printing, a wire drawn by an electromagnet acts on the arm between the pivot axis and the rounded end. A plurality of arms and electromagnets are spaced apart along a lateral row and mounted on a carriage for reciprocal lateral translation over a distance approximating the space between arms to print an entire horizontal row of dots forming a portion of a character line. Arms are driven separately or in combinations. The gap in the electromagnet is simply fixed to reduce power requirements.
