What is the status of printing to a Zebra printer (such as the ZTC230) via https through a Javascript POST request? I've seen various mentions on this forum saying that it is still not supported. However, browsers are getting closer and closer to disallowing mixed content entirely, and I want to avoid one day updating Chrome and finding out my printer integration has stopped working. Additionally, every page I print labels from now has the "Insecure" warning in the browser, which does not inspire confidence for our users.

I can't use web sockets as then that removes the ability to print directly from a website (where I have UI to created/edit/adjust labels).
