I’ve run into this problem a couple of times in the past 2 years and it takes me too long to find the resolution, so I’m posting it here.
HP ToolboxFX is a system tray program for some HP printers. From time to time, a system change causes the program to fail on reboot and you receive an alert message (see picture below) stating “HP ToolboxFX has encountered an error and can not recover.” Once the error is displayed, I can’t print anything. It’s likely do to some change in IP or USB port numbers, but here is the quick fix:
- Go to the following directory C:\ProgramData\Hewlett-Packard\ToolboxFX\Settings
- Under this directory delete all the files in Settings folder
- With the printer connected and on, reboot the PC
