HP 4650 printer not connecting to Macos 10.15.4

[Oloap]

My HP OfficeJet 4658 printer does not connect anymore to my macbook with MacOs 10.15.4

Tried to delete the printer and add again but the macbook can't see the printer.

Tried the HP Smart app but the printer won't be seen.

Printer with latest firmware.

Macbook with latest MacOs 10.15.4.

How do I fix this???

@Oloap, Welcome to HP Support Community!

Assuming that the printer is connected wireless to the computer, try the steps below-

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.

To be able to assist you better, I would like to know the following:

• Are the printer and PC connected to the same network?
• Is your router dual-band enabled i.e., both 2.4GHz and 5GHz?
• What is the distance between the router and the printer?
• Is there any antivirus software installed on your computer?
• 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.

Keep me posted for further assistance.

I had tried all the troubleshooting suggestions on the HP support site already. I posted here to get something more than a cut and paste of boilerplate suggestions.

Is there any known issue with my HP 4650 printer and MacOS 10.15.4?

Please refrain from replying more boilerplate responses with more questions to than actual answers.

@Oloap

Those questions will actually help us isolate the issue.

Please respond for further assistance.

Thanks for understanding!

Hello - I am having the same issue as identified on this thread. I have deleted all drivers and reinstalled, I have reset the printer to factory defaults, and am still having no success in establishing a wireless connection between my Mac running 10.15.4 and the printer.

I am able to print via email, so that should validate that the wireless connectivity on the printer is indeed working. The issue seems to be stemming from Mac OS 10.15.4 since it occurred immediately after I installed that update.

I did perform a ping test using my printer IP and all attempts timed out. It looks like there is an issue with the current HP software and the latest version of the Mac OS.
