@TuNiqa, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Are you using HP genuine cartridges in your printer? If not, I recommend getting the HP genuine cartridges for optimal performance and to avoid issues like the "Printer Blocked" error.

First, unplug the printer completely, turn off your laptop and router, wait one minute, then power everything back on. 

Next, let’s remove any old settings that could be causing problems. On your laptop, go to Control Panel > Devices and Printers, right-click your printer, and select Remove device. Then, go to Device Manager, under Print queues, and uninstall any drivers related to your printer. Now, reinstall it using HP Smart, this is the easiest way to ensure your printer is properly set up.

If the printer still doesn’t show up or keeps going offline, check your Wi-Fi network and make sure it’s connected to the same network as your laptop and phone. If possible, assign the printer a static IP address in your router settings so it doesn’t keep "disappearing."

If all else fails, try a factory reset on the printer (found in the settings menu) and start fresh. I know this has been a headache, but you shouldn’t have to throw it out. Let's get it working and make that printer earn its keep! 😊
