Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Can you try holding shift when you start up your Mac to boot into Safe mode?

Let me know if it prints ok in safe mode?
What does the detailed crash report say? (check the system event viewer or reliability reports)
