Can ping printer after Mac OS upgrade to Cataina 10.15.3

[griley]

My printer worked fine up until I upgraded to Catalina 10.15.3 Now I can't get it to go online and I can't even get it to respond to a ping. I've tried reseting printers re-added re-loaded current drives etc.. Still no go.

Any ideas?

Hi @griley

Welcome to the HP Support Community. I'd be happy to assist you with the connectivity issue. 

Let's try the below steps to see if that helps -

1.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks!

2.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices is using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

3.) Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it.

4.) Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source.

I'd also like to know the following to isolate the issue further-

1.) Are the printer and Mac connected to the same network?

2.) 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.

3.) What is the distance between the router and the printer?

4.) Is there any antivirus software installed on your Mac?

5.) 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 WiFi 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.  

Try updating the Mac using these steps - How to update the software on your Mac

Also, update the printer's firmware. Here's a document with step by step instructions - HP Printers - Updating or Upgrading Printer Firmware

Before I do all the tests here are a few more details.

1) My Mac is up to date with Catalina 10.15.3

2) The issue started when I upgraded to the .3 version a couple of weeks ago.

3) Yes both printer and mac are on the same wireless network

4) the SSID for both 2.4 and 5.0 is the same

5) I have an old Mac Air and my wife has a MacBook Pro. Both use older versions of Mac software and both can print with no issues using the same wireless network

6) Catalina dropped support for SMB 1 authentication so I can no longer authenticate to my NAS (just a FYI on Catalina)

7) SONOS music app can no longer works since Catalina upgrade.

Thanks for replying!

The information you provided is good to know, also we need the prescribed test results to assist you further with the printer offline issue.

Follow the instructions from the previous response we provided and share the outputs of the same.

Keep me posted.

I resolved the issue by deleting and resetting printer on the Mac.. then re-added and select AIRPRINT under "USE" setting. All working fine now.

Thanks to all.
