PSU Control - Pi and PSU control shutdown issue

what does Disconnect on power off do? When I press shutdown in octopi should it turn off the PSU as well as shutdown the Pi? If so it fails to do this (but manually pressing the PSU icon does work). How do I troubleshoot this.

BTW I use PSU Control with PSU Control - TAPO plugin.

disconnects from the printer.

It likely won't do that, as a system shutdown doesn't allow for many tasks to be performed right before it happens. Unless you see a specific setting to do this I would not expect this to happen.
