AirPrint stopped working with macOS 10.15

[JWalkerATL]

My HP OfficeJet Pro 8600 has worked perfectly for years using AirPrint (Bonjour). Recently it has stopped working and I can no longer AirPrint via my iOS devices or through my Macbook(s) - all running macOS 10.15.

macOS (MacBooks)

When attempting to print through macOS 10.15, the job will go to the queue and just sit there with message "Printing - Connecting to Printer" but the job never completes. I have tried this on 3 different MacBooks. I removed the printer in System Settings and then attempted to add it back. I can see the printer and select it with "Use: AirPrint" and it will attempt to set up, but then it will throw an error:

iOS (iPhones & iPads)

When attempting to print through iOS, I can see and select the Officejet Pro 8600 in the print dialog and it will say "Printing to Officejet Pro/Contacting Printer" but will never print the job.

@JWalkerATL, Welcome to HP Support Community!

I understand you're unable to connect the printer wirelessly on your iOS or Mac OS devices, let us first try to isolate the issue-

• 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.
