They can pass it, and suddenly it makes sense to put those restrictions on all the printers going to the US, because setting up a WA only export division with a separate production process costs money.
This is how California has effectively created national emissions standards in new cars for the last 30 years. It’s why you sometimes see Europeans on the internet asking “what the fuck is this prop 65 warning telling me that everything I own is poisonous?”
That’s a really good idea. This thing is stupid in the best way.
