Problem when using scanner:'Failed to open connection'.

I'm using USB cable connection between my iMac and the HP printer.

I'm using MacOS Big Sur version 11.6

I'm using the HP Smart software to scan, but there are a problem with the connection 9 out of 10 times.

How do I solve this problem?

Hi,

Please follow below version of HP Easy Start, as soon as it launches open the top HP Easy Start menu and select Uninstall HP Software.

Follow the steps on screen and then click on Set Up New Device and follow the steps to reinstall the printer:

As soon as HP Easy start prompts to install HP Smart, close HP Easy Start and press the Skip to Software Download button, then follow the steps on screen to complete the installation and check for any difference.
