ABSTRACT:
A printer which may be used in a billing/accounting machine having a single servo motor to drive both the printing mechanism (horizontal motion) and the record media feed (vertical motion). While the printing mechanism is always engaged with the servo motor for transportation across the record media, provision is made for disengaging the record media feed from the servo motor during the printing mode and for re-engaging the record media feed with the servo motor during the non-printing mode for the proper feeding of the media past the printing mechanism to provide line-by-line printing. With the printing mechanism continuously engaged, its exact horizontal position is always known and controlled.
