If label is getting stuck (usually during printing something really dark such as a barcode or a thick straight line), this is most likely due to the high print density of your label. 

  This causes the label to get too hot and get stuck to the Printhead. In fact, different labels require different heating temperatures. 

  Set your print speed to "4 in/sec" and density to "2" and try print again. If the label is too light, increase the density by 1.
