I keep having an issue with my rMBP and my HP Deskjet F4280. My macbook recognizes the printer, and when I go to print something it says that the document is being printed and even shows a status bar, but the whole time nothing at all is happening with my printer. My macbook thinks its printing but really nothing is happening. I have tried waiting for the printer to react, even once let it wait for 20 minutes, still nothing. How on earth can i solve this problem? Its really starting to stress me out. I am running OS X Mavericks 10.9.3 if it is relevant.
