Just bought an HP Envy so that I could print easily from Macbook Air, iPad and iPhone. Starting with Macbook Air. Both are connected to the web via Airport Extreme. Can add printer to Air via IP address, but it really doesn't see it and won't print.
Are the printer drivers installed? You should not use the drivers from CD as they are alyas old.
If the driver inn't installed, plug the printer in via USB and go to the Apple menu and select Software Update. That should install the software.
If that fail, you may need to call HP to see if the printer is indeed connected to the Airpot network properly. You should not have to set it up by IP address. It should should show up as Bonjour.
