Abstract
A recording head of a current application type serial printer is provided with two independent recording electrode groups on both sides of its tip. The angle of contact of the recording head with a platen of the printer is switched between a forward printing stroke and a backward printing stroke of a carrier so that, usually, the electrode group on the right-hand side of the recording head is used during the forward printing stroke, and the electrode group on the left-hand side during the backward printing stroke.
