Maybe find a used compressor that still has the original sticker? It would have to be a nice one, though. Theyre usually all scratched up. I doubt that you could take a picture of one and print it because the sticker wraps around the compressor, ad the perspective would change around the sides. You might be able to reproduce it in a paint program and then print it. Maybe take a few pictures going gradually around the compressor, paste bits of them together and clean them up until it looks right? Im just rambling, but maybe Ill give you an idea. I once used a printer and a sticker to put a custom scale on a gauge, and you really had to look hard to tell that it wasnt original.
