Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Could you perform a ping test using the Mac Network Utility and let me know the results? 

Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display. 
 

The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold option-click the Wi-Fi icon and then use shift-command-5 to take the screenshot. Press the space bar when the icon turns into a camera. Share the ping test results and the screenshot with us. 

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. 

Hope this helps! Keep me posted for further assistance.
