HP ENVY Pro 6420 Suddenly always showing "offline"

[Daniela1107]

I have had an issue since the day I purchased the printer where it shows it's "offline." However, we simply unplug and replug it back in to fix the problem for that moment. Suddenly now that method is not working. I've tried 4 different methods suggested by the Virtual Assistant bot and for some of those methods, I've tried 3 or more times. Nothing is working to get it to reconnect to my wifi. These methods did include restarting my router as well. Please help! Thank you.

Welcome to the  HP support community.

I understand that you are getting printer offline error, I am glad to assist you.

I'd 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 an antivirus software installed on your Mac?

5.) 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

1. Click Applications > Utilities > Terminal.
2. 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.
