Use XPS for printing from PDF

When enabled, use XPS printing API instead of the GDI print API when printing PDF documents. – Windows

#use-xps-for-printing-from-pdf

I found these information so far

https://mspoweruser.com/google-chrome-uses-xps-print-api/

https://docs.microsoft.com/en-us/windows/win32/printdocs/about-xps-print-api

https://docs.microsoft.com/en-us/windows/win32/printdocs/gdi-printing

but I can see no difference in Edge insider latest version with those flags enabled and disabled
