If your printer always prints some empty labels before it starts printing your PDF files, in our experience, this issue is usually caused by:

  1. Paper sensor malfunction.
  2. We do not support the label paper.

Paper sensor malfunction

For item1, the best approach is to seek assistance from your printer manufacturer. We specialize in software development and the issue at hand primarily relates to firmware and hardware.

We do not support the label paper

For example, the ZEBRA 2.2" X 0.5" 8000T JEWELRY LABEL is unsupported because the printer driver does not support printing PDF format on particular model.
