Something is broken with RD Easy Print Driver in (at least) Spanish Installatons of Window Server 2016 and 2019. It will NOT show no matter what you try to configure (spent a lot of hours and headakes). I have tested the same steps installing Windows
Server with English ISO file an it works perfectlly!!!. The problem is with the Spanish ISO es-ES (at minimum), maybe if you install Windows Server 2016 or 2019 with any non-english ISO.
This problem is known by some people in the spanish "community", but no one on Microsoft is scalating this problem properly because it is not fixed yet since a couple of YEARS!!! This is happening since the launch of Window Server 2016 at least, I think it works with 2012r2 if I remember well, but I am not sure..
I hope someone can scalate this Bug with support services. THANK YOU!!!
