I have no idea, we always have gotten pre-printed tags. However, why don't you just call Royal and ask them? Their # is 800-526-9723. A question of this type should fall within their limited capablities.
The porters at the dock have this information -- we changed cabins-- post our tags being printed -- and had to hand fill them in at the dock -- this only took a few minutes. If you cant find this information, just find a porter -- they have a master list of all the quadrants. I think i'd trust this information over a phone call --
