@Nathan2709, Welcome to the HP Support Community! I’m here to help.

I see that you are not able to print wirelessly. If the wireless light is blinking, it means the printer is not connected to the network.

Restart the router, the printer, and the Mac. Check if you are able to print.

If not, kindly follow the steps mentioned in this document -  Connecting an HP Printer Using Wi-Fi Protected Setup (WPS)

• Make sure the printer and the Mac are connected to the same wireless network. 
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

• This printer supports WPA/WPA2 encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK
