ABSTRACT:
An improved method and apparatus in a printing device having a printhead displaceable along a record carrier. The record carrier is supported beneath the printhead by a platen. The improved apparatus includes a mechanism for spacing the printing distance between the printhead and the record carrier. The spacing mechanism is positioned to bear upon the record carrier in advance of the printhead. A mechanism urges the platen away from the printhead and the spacing mechanism so as to permit a ribbon mechanism to be inserted between the printhead and the platen.
