If we reach the $20,000 goal and move to the 3" head, we may have custom rolls made that aren't quite as thick in order to keep the physical size of the printer down. However, even if we do that - you can still use standard 3" paper without purchasing anything special from us, and just remove some to make it fit properly into the case.
Absolutely! We plan to, at a minimum, make AC adapter options available for Europe, the UK, and possibly Australia. Even if we don't have a special AC adapter for you, the cord will be swappable and is a standard part.
