A simplified printer device has a print body on one end of which a print head is mounted, the print body being longitudinally movable along an inking stroke and being longitudinally movable along a printing stroke, with the printing stroke being angularly offset by approximately 90° from the inking stroke, and with the print body being pivotally movable through an intermediate pivot stroke between the inking stroke and the printing stroke. A piston and cylinder assembly is connected to the print body for operatively causing advance movement of the print body along the inking stroke, the pivot stroke and the printing stroke, and return movement of the print body along the printing stroke, the pivot stroke and the inking stroke. The print body has a longitudinally elongated slot, and a fixed pivot pin is disposed in the elongated slot in the print body for guiding the print body, a first freely rotatable roller restraining the print body against pivotal movement during advance movement of the print body along the inking stroke. A channel in the print body is in alignment with the first roller at termination of the advance movement of the print body along the inking stroke whereby the print body undergoes advance movement along the pivot stroke during which the first roller passes through the channel in the print body. A second freely rotatable roller terminates the advance movement of the print body along the pivot stroke and restrains the print body against pivotal movement during advance movement of the print body along the printing stroke, the first roller restraining the print body against pivotal movement during return movement of the print body along the printing stroke. At termination of the return movement of the print body along the inking stroke the print body undergoes return movement along the pivot stroke during which the first roller passes through the channel in the print body, and return movement of the print body along the pivot stroke being terminated by a third freely rotatable roller, with the second roller restraining the print body against pivot movement during return movement of the body along the inking stroke.
