@hxr1, Welcome to the HP Support Community!

Let us try these steps to resolve this issue:

Update the printer firmware

Click here to download and install the latest firmware from your MAC.

Restart the wireless router, the printer, and the MAC

• Make sure the printer and the MAC are connected to the same wireless network.
• This printer supports only 2.4GHz network. So, the MAC should be on the 2.4GHz 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 the networks.

Perform a ping test to check the connectivity between the MAC and the printer

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. On the MAC Go to Spotlight > search for Network utility > select Ping tab > enter the IP address of the printer in the box
3. Check the second box that says Send only > 10 pings
4. Click on ping > Check the results at the end if any packets are lost
5. Note: There should be 0% packet loss, share the results in your next post.
