Create virtual printer using Print Support App (PSA)

Question

Hello .net community,

I'm trying to create a UWP PSA application following the https://learn.microsoft.com/en-us/windows-hardware/drivers/devapps/print-support-app-v4-design-guide guide. However when I deploy an app locally, the virtual printer is not created. The app does not have aany, just configuration file with dummy background tasks.

Am I correctly understood the manual, that PSA v4 is able to act as virtual printer, without need to develop any printer driver, and virtual printer should be created automatically after installing such PSA app?
