If the local baker said that, then that would be a red flag to NEVER do business of ANY KIND with that baker, nor send ANYBODY there for ANYTHING. Food safety is NOT something to play fast-and-loose with. If it's intended to be edible, do it right (a cake supply dealer, rather than a baker, would be the preferred place to farm out edible printing). And if it's not intended to be edible, then (1) make it physically impossible to eat it, and (2) isolate it from the cake.
