Printer Won't Connect to Network - duplicate IP address error on printer panel

I have an HP printer connected by wifi to my Orbi network. We use Apple macs. Regularly things don't print - and when checking the printer panel, I see 'Duplicate IP address' on the printer panel. This sometimes (but not always) goes away after a minute or two - and then things start to print. I have now assigned a static IP address to the printer and even tried reserving this address on the Orbi system, but the problem continues. I am trying to understand what would trigger the duplicate IP call. Could it be the Orbi sattelite and Router making a simultaneous call? Is it something completely different? Any ideas for a solution?
