Printer connection issues

A friend has recently bought an M1 MB Air which I have been helping her to set up. Everything has gone well, apart from a curious printer connection issue. The printer is a brand new HP Laserjet Pro M255DW Wireless colour printer. On unboxing and first connection, all worked well, with the wireless printer driver installation going as expected and a few test pages printed correctly over the local (home) wi fi network. The next time I tried to print, as part of my ongoing assistance to the user, the printer failed to work on the home network. We successfully created a wired (USB) connection and I then set up the MBA to print wirelessly using the Printer's HP wireless system, but this involves removing the internet connection and connecting to the printer's native network - a workaround, but inelegant. When trying to re-install the printer on the home wifi network I get the error attached (pictured). The printer in question works fine printing on the home network using my 4 year old MBP, and my friends iPad. I have updated the printer firmware, having checked the HP website. I wonder if anyone can help with this issue. TIA, David.
