E-Print doesn't work on MAC OS

[DMHWS28]

My MacBook running on Mac OS Big Sur 11.2.1 doesn't allow my to connect to my printer using airprint. It works from other devices like iPhone or a Windows PC. It worked before seamlessly on this machine. I believe the problem occured after an upgrade to Mac OS Bg Sur, though I'm not sure about the exact point of time.

The printer is found in the "Add Printer" dialog window. When I try to add it, the Mac tries to configure the printer but fails with an error message (translated from German): "An error occurred when adding a device.  Currently not communication with the printer is possible.

When I start HP Smart, I first "forget" the printer and then add it again. It is found and reported as "online", HP Smart continues to the point where it says I'm ready to print, I only have to add it to the printers in the Mac as described above.

The printer is connected to my WLAN via Ethernet. As wireless printing works OK with other devices, I assume that the connection is OK. I also tried to restart the printer without effect. Restarting the access point to which the printer is connected doesn't work either. 

Any ideas?

@DMHWS28, Welcome to HP Support Community!

To be able to assist you better, I'd 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.

Thanks for your reply. Meanwhile, I was able to fix the problem myself: The printer was visible in the wireless network, but my Mac was trying to connect to it using an outdated TCP/IP connection. I shut down Mac, PC, and router and re-started all 3 in reverse order, i.e. router, printer, Mac. After that, connecting to the printer worked.
