My HP 8730 Printer is network-connected - no cables. I print from my Windows 10 computer and my iPad and iPhone. When I turn on Norton Secure VPN, the printer goes offline. When I turn Secure VPN off, the printer goes back online. In a previous thread, I read of a solution where I can completely uninstall the instances of the printer, including fax printer, then turn on Secure VPN, then reinstall the printer instances. The iPhone and iPad do not use Secure VPN; it's not clear what would happen with them. It sounds complicated. If I get further insight on this from HP, I will return here and share. Bottom line, Norton Secure VPN may not be worth it given this issue. Norton 360 the latest version.
