Welcome to the HP support community.
I'd like to know the following to isolate the issue further-
How is the printer connected?
Are the printer and Mac connected to the same network?
Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual band has different SSIDs for 2.4G and 5G networks.
What is the distance between the router and the printer?
Is there antivirus software installed on your Mac?
Could you perform a ping test 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.
Perform a ping test to check the connectivity
- Click Applications > Utilities > Terminal.
- type ping "IP address" and press enter
Wait until 10 pings have been performed and then press ctrl c on the keyboard and hit return.
The results will appear.
Share the ping test results.
Keep me posted.
If this helps, please mark the public post as an accepted solution so that it benefits several others.
Cheers.
