HP Officejet Pro 8620 not recognised on Mac OS

[gicela]

Hi,

Wondering if anyone can help. The recent Mac OS updates have stopped my printer from working. It simply doesn't recognise it. I tried everything. Printing works from my iPhone with no problems.

The latest error I got is this after trying to install the software again.

"Unable to connect to ‘HP Officejet Pro 8620._ipp._tcp.local.’ due to an error." (this error is using an old MAc version (Mac OS catalina10.15.7)

I also downloaded HP Smart app and it can not connect to printer either. Tried this with the new mcOS Big Sur 11.3.1

Any help would be appreciated.

Thanks.

@gicela, @Chris365 Welcome to the HP Support Community!

First, let us check the connectivity between the devices to resolve this issue.

• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz 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.

Update the printer firmware

Also, check for any software updates on Mac

Click the Apple icon > About This Mac > Software Update and install any available update.

Perform a ping test to check the connectivity

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
3. Enter “ping” followed by the IP address of the printer. 
4. Press Return. Press ctrl C after 10 pings
5. There should be 0% packet loss, share the results in your next post.
