If you buy the same printer in different counties do the dots persist or change?

I thought they were unique per printer not just type. More akin to a serial number instead of a model number.

That is my understanding. And I assume the dot patterns are made by printers worldwide. The article mentions Dutch law enforcement using them, and German researchers studying them.
