My main concern is, how long is it before you can't print a replacement part for something you bought because it looks too similar to an OEM part and the manufacturer doesn't think you should be able to do that so they throw a little money to the right politician.

At least 25 years. That's the time passed since the first introduction of Eurion marks on banknotes. As far as I know, noone has used it to block reproduction of anything other than money.

Actually I tried to use it just for fun on some vouchers, but it didn't work on the copy machines I tried. They just happily photocopied the vouchers.

Tried the same, doesn't do anything on my scanner. Interestingly, there are regions of banknotes my scanner refuses to scan. But had no time to investigate further.
