Abstract
Official abstract text for this publication.
A printer may include a printhead assembly a clutch assembly, and/or a printer ribbon transport assembly. The printhead assembly may include a printhead biasing assembly defining a biasing ramp which may be configured to apply a biasing force to a printhead support bracket so as to at least partially counteract a ribbon force. The clutch assembly may be configured to supply or take-up a printer ribbon with first and second spool engagement members of different diameters that frictionally engage first and second friction members. The printer ribbon transport assembly may include a rotation lock mechanism configured to prevent rotation of a ribbon take-up core when the take-up core is disengaged from a drive assembly so as to prevent a loss in ribbon tension.
