Hi, I suddenly had a probem whereby nothing would print from my Chromebook to my HP Envy 4507 having successfully been printing via Cloud Print for 2 years. I uninstalled the printer from Google Cloud print, but now the printer does not show up anywhere to reinstall it. The printer shows as connected to network (as is the chromebook) and the printer can print a test page when I tell it to from my HP IP address account online. However, it is no longer an option to print any other page. I have tried restoring default settings to the printer, switches everything off and on , disconnected and reconnected the printer to the network. Am at a loss as to what else to do - Please help!
