Hello there, welcome to the forums:)
I noticed both of your posts and wanted to reach out. I understand you are seeing that your printer is "offline" and it will not connect to bluetooth. Here is what I suggest trying:
2. Mac OS X: How to reset the printing system
4. Add the printer back by using the ' + " sign
Now see if you're able to connect to bluetooth.
I hope this helped!
Enjoy your Tuesday!:)
