Abstract
In a magnetically operated matrix printer a circuit makes a decision when a magnet is actuated. The decision is whether or not the relevant magnet has already been actuated during the printing of the previous column of the matrix character being printed. When it has not been actuated, it is actuated with a larger quantity of energy (longer pulse). Thus the operation of the printer is in 'resonance' with the mechanical movements of the magnet armature.
