You would also hope that people would heed the warning the Apple give with every pre release 'ONLY USE ON A DEVICE INTENDED FOR BETA TESTING' If printing isn't working, then the only people to blame are end users stick a beta release on their working machine!
I agree, however in the public beta if Apple knew that printing was borked you would think that they would fix that before releasing the update, unless… they are testing our reaction to not be able to print because in 10 Months time, Tim will be standing up and announcing 10.15 ‘High Mojave’
“Here in Cupertino we love our trees, and we think you should too. Today we are announcing a new feature, ‘Document Teams’, at a flick on your trackpad, wireless transfer a file to all members of your team in an instant so that can be viewed on any Apple device. Following removal of floppy disks, optical disks and more recently headphone ports, today we are showing courage to remove printing to paper, to save our trees”
