Abstract
A thermal printing mechanism has a printer head for printing on a flat object transported in a transport direction through the thermal printing mechanism. A roll lever is pivotable about a pivot axis at its first end. A counterpressure roll is mounted to the second end of the roll lever and supports the flat object for printing by the printer head. A freely rotatable roll is positioned in the vicinity of the printer head and mounted in a fixed position relative to the pivot axis. A mechanism for adjusting a position of the counterpressure roll at the freely rotatable roll in accordance with a thickness of the flat object passing between the counterpressure roll and the freely rotatable roll is provided and the print head thus always applies the same pressure onto the object to be printed.
