Printers and AD - Deploy? Publish?

Hi all --

I am in the process of upgrading my primary print servers from Windows 2008 R2 physical to Windows 2012 R2 virtual.  I've got all of the printers / drivers / ports migrated.  These printers are shared off of our print server.  My question is - what is a reason to publish the printer in AD?  Furthermore - on the print server itself, why would I deploy a printer (in the print management console).

We haven't done this in our organization and I am wondering what benefit it provides.

Thanks in advance
