Can't print wirelessly to an HP Photosmart C4780

[flopperr999]

Hi,

I can print to a HP Photosmart C4780 from my MacBook Pro when the USB cable is plugged in, but I can't figure out for the life of me how to get it to work wirelessly. My network has a WPA password. When I print out a "Network Configuration Page" I can see that the printer is "seeing" my network, but it is not connecting to it. In System Preferences I have the printer set to shared and in the Network tab of System Preferences I have Printer Sharing enabled. I have no bloody idea on what to try now, been working at this thing for three hours now.

PLEASE HELP!

Thanks

Have you ever entered the WPA key during the setup? Since your wireless network is protected, the printer won't register it until you give it the WPA key.

Make sure there is nothing related to USB on the System Preference if you want to print wirelessly.
