Cannot ping or access my wireless printer - urgent!

[Gordonbp531]

HP Envy 5640 Ubuntu 22.04
My printer suddenly stopped working
I can't access the IP address in Firefox (but I can access the IP address on my iPad).
The internet and WiFi network is working properly, .I can access the router via Firefox which shows the printer IP address.
Firewall is disabled.

Printer works perfectly well from my iPad......

HELP!

Sounds like the iPad is communicating directly to the printer (Wifi - Direct).

Have you tried the good ole pull the power plug on the printer, wait 10 seconds
and plug it back in?

This is utterly, utterly bizarre.
I closed down and booted into a Live version of Ubuntu.
Everything worked as it should.
I rebooted into my SSD installation, and all of a sudden, everything works.
Utterly utterly bizarre.
