V3 does the same thing for me. Shows the many printing popups but doesn't print anything. I've noticed it I just sit there and let it simmer, it eventually (couple of minutes later) will print but nobody has time to wait like that.
This is an interesting report, and we definitely want to take a look! Please reach out to our support team about this behavior with full details and a potential test order for investigation.
