drupal commerce – Unable to print labels in Commerce_POS

I'm running a new Drupal installation with trade & commerce_pos. I have some test products with variations. I also have jquery installed with dial. My problem is that when I try to print labels, all I get is a blank print. This occurs in Chrome and IE. Ideas?

Drupal core 8.6.15 | Commerce 8.x-2.13 |
Point of Sale Trade (POS) 8.x-2.5
