ABSTRACT:
Apparatus for printing characters on at least one data carrier comprising a printing head movable along the data carrier, a line advance device for feeding the data carrier substantially perpendicular to the moving direction of the printing head, an ink ribbon feed mechanism for feeding an ink ribbon in relation to the data carrier, a cut-off mechanism for cutting off the data carrier, and a shaft rotatable less than 360.degree. in one direction by a reversible motor from a home position to an end position determined by the selected operation cycle and thereafter back to the home position by reversing the direction of rotation of the shaft. The reversal of the shaft is performed at different times during subsequent operation cycles to permit gears and cams on the shaft to move the printing head to positions determined by the number of characters to be printed on the data carrier, actuation of the line advance device, and actuation of the ink ribbon feed mechanism or cut-off mechanism. A unit for printing normally unchanging information is activated in response to the motor providing a short backing movement before operation of the cut-off mechanism and before the printing head is moved from the normal neutral position.
