The thermal printhead generates the print image via pointwise heatingof the label medium.Thermal transfer printingPointwise heating by the printhead causes color particles from the color coating of a ribbon to be trans-ferred to an uncoated label medium. The ribbon can only be used once for printing. A great variety ofmedia, e.g. normal paper, cardboard and polyester film, are suitable for thermal transfer printing.The print quality essentially depends on how well the coloring from the transfer ribbon adheres to thelabel medium. Ask your dealer for advice when selecting labels and transfer ribbons. Run tests if nec-essary.
