ABSTRACT:
A printer having at least one reciprocally mounted printing member controlled to impact against a printing surface by selective energization of an associated printing driving member. The forward end of the member is guided by a bearing. Ink from a supply source is directed to the printing member near the forward end of the printing member whereby the ink is drawn into the region between the guide hole in the printing member guide bearing and the periphery of the printing member to be moved to the region in front of the forward tip of the printing member whereby activation of the driving member abruptly moves the printing member in the forward printing direction causing the ink deposited upon the tip of the printing member to be urged toward and against the ink receiving medium to transfer the ink to the ink receiving medium. A group of printing members may be used to print in this manner to collectively form characters, symbols, and even graphic patterns.
