Abstract
A device for biasing at least one thermal printhead into uniform, tangential contact with the printing media includes a shaft supported by a housing, an assembly rotatable about the shaft for supporting at least one thermal printhead, and at least one biasing spring for establishing and maintaining adequate torsion on the supporting assembly so as to substantially minimize or eliminate positional instability of the printhead. In the event a plurality of thermal printheads are utilized, the biasing spring also simultaneously compresses each of the supporting assemblies so as to substantially minimize the gap between each of the printheads while maintaining the gap dimensions substantially constant.
