Printer Que Not Quitting Automatically in Leopard

Hey all. I have an HP Deskjet 5650 printer, and in Tiger, when I printed a job, the printer software/que opened up for the duration of the print job, then quit once it was through. In Leopard, however, it just stays open after a job is done, and then I have to manually quit it. Not that this is a huge hassle, but I don't like having programs open I don't have to. Is there a way to set the printer to quit automatically that I've forgotten? Thanks for your time!
