Before I started looking into getting my CCW (1 month to go before i get into ElDorado county, YAY) I had no knowlage of the word "Printing". It seems to be a relatively obscure word to use in general conversation. Most people that would overhear would have no idea what you are talking about in the first place. Seems pretty safe to me to just say, "Hey, You're printing" smile nod and go on my way.
