While it seems than win10 pro can expose a print server, I've tried to experiment a bit to understand if this print service can be used as a role in our domain.
Basically other machines can see the printer in the win10 machine if added via print management, but those printers are "volatile" (do not persist at reboot) and aren't pushed via GPO.
Before digging in possible errors on my side I would like to understand if I can use the service as in a win 2008 print server role.
No, Workstation operating systems are not suited for server roles.
Its not good idea cause OS like Windows 10,8,7 are for simple users...what i mean is they cannot accept a lot of new TCP connections and will fail after a short of time, thats why you should use server OS like windows server 2012
