If I want to apply a finger print on stainless steel, would I cover the area with beeswax, touch it, and then put it in the acid bath?

No. The purpose of the wax is to protect the area you do not want etched. The design you want etched into the metal has to be on the part that is not covered by the wax. Maybe if you dipped your finger in something, like oil or paint, then pressed that print to the metal, it might create enough resistance on the ridges of the fingerprint for it to work.
