Universal Print set up requirement

Nickson_Easow I will try and answer your questions as a whole. 

Universal Print acts as a Print Service accepting print jobs from clients and sending the jobs to the printers. 

Printers that are UP- Compatible would be able to register as AAD devices and be registered in the UP portal. These printers would then be notified and would pull down the print jobs directly from UP. Currently there aren't any UP-compatible printers in the market, but we are partnering with the major print IHVs for future devices. 

In the meantime, the Connector service is designed to provide the communication between a Windows Server 2016 or later to publish a locally installed printer to UP. It handles all the notifications and retrieval of print jobs from UP on behalf of the local print queue. You would create the local print queues on the server using a printer-specific driver, and then use the Connector to expose and register those printers with UP. 

An on-premise AD is not required. The Connector can be installed on a stand-alone or workgroup machine with the local print queues. The Connector is registered with UP using an AAD account with the Global Admin or Print Admin role. Once the printer is registered and shared, the Connector service, and as such the server it is installed on, must be running for the print job to succeed. There is no fail-over solution at this time for the Connector. 

As for pushing out printer connections, we are working on that functionality via Intune and other possible options.
