The first step on the HPLIP troubleshooting page is to check for device support.

The supported printers list on the HPLIP developers site and their release notes don't explicitly mention 3720, so there may be an issue with trying HPLIP.

Two similar Deskjet models (the 3700 All-in-one and 3722 All-in-one) are explicitly listed as being supported. As 3720 isn't on the unsupported list there is some doubt over support. It may still be worth following the HPLIP troubleshooting steps (above) to verify your connection and device discovery.
