It appears the print plugin was not loaded/imported for some reason
This can happen if you are loading another instance of jQuery after loading jQuery.print or if an error occurred while loading it in the first place (which would show up on your console)
Kindly re-check your code flow and create a simplified demo showing the issue for us to help you
