I'm running Leopard on multiple Macs, with networked LaserJet printers, and they all have the same minor problem. Whenever I print, the printer application opens (letting me see the status of printing if I want) but never quits on its own. It's left in the dock until I quit it manually. I'm pretty sure this isn't how it used to work. Is there a way to keep the printer application from being visible in the dock or to make it quit automatically when the print queue is empty?
