Zebra GK420t printers are both direct thermal and thermal transfer - so can use both types of labels, all of which are supplied on 25mm cores. If you are using thermal transfer labels, then you need to use a thermal transfer ribbon to produce the image - we sell Zebra thermal transfer ribbons for the GK420t printers here. The Zebra GK420t printer has a maximum label width of 102mm - please be sure to select the correct labels for your printer.
