An elegant way to control a MKS PWC?

I was originally going to control power to my printer with an external relay, but realized it uses a MKS PWC, which basically is a relay. Does anyone connect a Pi GPIO pin to it for power on/off? Or disable it, and do it externally?

If I remember right, the plugin PSU control can do something like this. I recommend having a search on the plugin repository, this has definitely been done lots before.
