I honestly thought this was a troll comment intended to show how ridiculous this sort of thing would be if region locking applied to printers. I was not pleased to find out that this is, actually, a thing.
it practically makes it illegal to even change the battery of a device you bought if there is not an user accessible and labeled port to change said battery.
So i am guessing that fiddling with the DRM software on the printer also is a crime under such idiot law.
