Part of the goal of dual-stacking is to enable IPv6 where you can.
Noone says you "MUST HAVE 100% IPv6-only EVERYWHERE".
Your printers, for example, can stay IPv4-only ... everything else (which probably already supports IPv6, BTW) can move to IPv4+IPv6 in a planned fashion.
The benefit: you are ready before you need to be, and don't need a firedrill style deployment down the road. Oh, and it really can be fairly straight-forward :).
