I’ve tried some other combinations now. I’ve lost track of all the details and I cannot repeat what I did now.
I first tested with another PC - all went fine there.
On this PC I first tried just changing the printer when first printing something from a regular viewport but it still crashed when printing from the layout after that. At some point I was able to change something [default printer | printer set from regular viewport] that made the crashing stop. I wanted to find out how to reliably repeat that and so I set the default Windows printer back to OneNote and Rhino crashed again. Now I’ve tried numerous combinations of everything but I cannot get it to not crash anymore…
Oh well… I guess I’ll just be not printing from this PC anytime.
