Since upgrading to mountain lion I have had difficulty getting my mac to find my printer (Photosmart C310: CE224B) . I was having to provide the admin password for the wireless internet connectioneach time I wanted to print or scan inorder for the mac to see the printer. Today this did not work at all. I followed mac support on the website and uninstalled HP software, and attempted to re-install. I installed HP mountain lion driver v.12.23.14 but this has not worked. My mac cannot see any printer eventhough they are sitting right next to each other! What should I do?
