Abstract
A thermal printer for printing onto circular objects includes a housing that mounts a platen and a carrier for the circular object, and a separate removable and latchable carriage carrying the printhead and positionable on the housing to retain the printhead in a fixed location. The carrier for the circular object is driven relative to the printhead while printing takes place. The platen, carrier and circular object are urged against the printhead as the carrier moves. An actuator is used for moving the platen and carrier with a variable force to vary the force of the circular object against the printhead so that the force is increased when the length of the line of printing increases to span the circular object.
