I am trying to help my friend finding a printer capable of printing on surface without touching it, for example if you want to print a code on an egg (don't know better comparison). He assures me that these printers exist but I just don't know how to look for it -> all he knows is that he needs a printer which can be used on printing on etiquettes, labels etc., from height of approx 1 or 2 centimeters. Anyone knows one model so I may search for similar ones? THANK YOU! EDIT: here is the picture of final product
