Many HP Printers will broadcast their own Wi-Fi Network, allowing users to connect directly to the printer instead of going through the regular network (Wi-Fi or Ethernet). While this adds convenience, IF the printer is also connected to your local network it is not as secure.
If a hacker gained access to the printer through its Wi-Fi network, the hacker can easily get to the rest of your network through the printer’s network connection. We recommend NOT having the printer accessible via Wi-Fi Direct if it is also on your local network (via Ethernet or Wi-Fi).
If you choose to turn off the Direct Wi-Fi network on HP printers, the printer can still be connected to your network via Wi-Fi. For instructions for specific HP printer models, I recommend searching for the phrase "disable Wi-Fi direct for HP printer " for your specific model.
