Snow Leopard Auto-Detects Printer?

I travel a lot between the office and the apartment, both of which have printers. Whenever I go to print on my laptop at either, Snow Leopard volunteers the correct printer -- I don't have to toggle back and forth between a default. This is a minor but totally awesome feature (I think) that looks for one of the installed printers and uses the one that matches. How awesome is that! I haven't once had to choose which printer to use in the last month since I've installed Snow Leopard.

Love you Mac!
