The printing system (10) is a dot matrix-type printer utilizing a liquid ink reservoir (12). A plurality of pins (44) are disposed within the reservoir (12), each pin (44) having a lower end and a tapered upper end terminating in a printing tip (48). In use, the reservoir (12) is held stationary, the liquid ink (I) being contained therein by gravity. A printing substrate, such as a piece of paper (P), is drawn over an open upper end of the reservoir (12). A driver (33) selectively vertically translates the plurality of pins (44), each individual pin (44) being selectively driven independent of the other pins. Each pin (44) is initially positioned so that the lower end thereof is located adjacent a lower wall (13) of the reservoir (12), and the printing tip (48) is positioned beneath a surface of the ink (I). A selected pin (44) is translated upwardly so that the printing tip (48) thereof contacts the printing substrate to form an ink dot thereon. |
