OfficeJet Pro 8600 error "The printer configuration is incorrect or the printer no longer exists"

[rehjaeger]

OK, I'm having some strange trouble here. I can print reports from HP Smart. WiFi is set up and showing connected. When I try to print a text document, though, the computer cannot find the printer. I have a 5 Ghz WiFi, but I have tried "pausing" it so that only 2.4 is active, no help (the printer says it's connected to the network). Tried updating firmware, (shows to have CKP5CN1829AR installed presently)  one  is showing (which is supposed to mean that there is one available for this printer) but when I download it and try to install it it says that there is not an update available in this package (or something similar) and doesn't do anything. When I try printing from photo paper (yes, in Tray 1) it gives the message above. I'm pulling my hair at this point. NEVER had this much trouble with an HP product. I'm on 10.15.7.

@rehjaeger, Welcome to HP Support Community!
 

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 was able to fix the problem by totally deleting the printer profile and starting from scratch. It seems the HP software was corrupted in some manner. Thank you, and I appreciate your response. I apologize for the late reply.
