One quick tip: disable IPv6 on the printer if it's enabled. Some home routers struggle with IPv6 neighbor discovery for older devices, and IPv4 is usually sufficient.
Try connecting your PC via an Ethernet cable to the router, then try printing. If it works, it points to a wireless issue on the PC's side or router's wireless settings, not the printer itself.
This printer model is usually pretty solid. Could it be a recent Windows update causing a compatibility hiccup?
It sounds like a mDNS or Bonjour discovery issue rather than a pure network connection problem. The printer's connected, but your devices can't find its service. Try rebooting your PC and phone AFTER the printer and router are fully back up.
Thanks for sharing your troubleshooting steps, it helps to know what you've already tried. One small correction, Windows 10 has built-in driver management so usually you don't need to manually update unless it's a very specific bug fix.
Are you on a guest network by any chance? Printers often require being on the main network to be discoverable.
Have you tried assigning a static IP address to the printer? It's a bit advanced, but it often solves these intermittent connection problems.
I second the static IP suggestion. It prevents your router from assigning a new IP every time and messing with discovery. You typically configure this through the printer's web interface.
Wait, the printer *confirms* it's connected? That's really weird. Usually, that means it's talking to the router, but not to your devices. Is there a firewall blocking it?
What does your router's client list show? Is the printer listed with an active IP address?
It sounds like a classic case of the printer being on the network but not being discoverable by other devices. Check if your router has 'AP isolation' or 'client isolation' enabled; that would block devices from seeing each other.
My Canon did this last month! Turns out its IP address changed, and my PC was still looking for the old one. A full router reset (not just power cycle) fixed it for me.
This sounds like a common issue with HP's Smart app. Are you using it? Maybe try printing directly from an app on your PC without Smart.
The HP Smart app is such a pain. I often have to uninstall and reinstall it when my printer decides to act up. It's not ideal, but it works.
Have you checked if your router has both 2.4GHz and 5GHz bands? Sometimes these printers get finicky and only want 2.4GHz.
