ABSTRACT:
A printing device having a printing head opposite a cylindrical anvil. The printing head is displaceable along a guide rod which is connected by pivotable arms to a pressure roller which is spring-biased against the anvil. The arms pivot about an axis parallel to the longitudinal axis of the anvil.
When the thickness of the record carrier changes, the distance between printing head and record carrier is kept constant by movement of the distance roller, which in a preferred embodiment is also used as a drive roller for transporting the record carrier.
