Hello Alan Mingo.
Thanks for trying the printer removal, restart, and connection changes, and for confirming the message still appears. Since it comes back even with the printer disconnected, I wouldn’t repeat those steps yet.
Could you share a screenshot of the entire message, including its title and any buttons? Please cover any personal details. It would also help to know whether it appears inside a browser, as a notification, or in its own window. That should help identify what is displaying it before changing printer settings again.
For now, please don’t click a “Fix Now” button or call a number shown in the popup. You can also run a Full scan from Windows Security > Virus & threat protection > Scan options as a precaution. I can’t tell from the message alone whether this is unwanted software or a genuine printer alert.
