123.hp.com – HP ENVY 4520 All-in-One Printer SW Download

MY HP ENVY 4520 won't connect to my computer. I tried using the USB connection and wireless multiple time. I tried to use the HP Publish and Overlook Croaker but it did nothing. In my bias and printers under HP ENvy 4520 it says" Motorist is unavailible". I've checked multiple times and everything is installed. The printer worked ahead but not it does not want to connect or the computer isn't allowing it to connect. Please help me break this issue. The printer isn't indeed a time old and it has not been damaged in anyway.
