I've noticed two options for deploying printers via group policy:
Create and link Group Policy in GP Management, add printer(s) via User Configuration > Preferences > Control Panel Settings > Printers.
Go to Print Management mmc, right click on printer share and select Deploy with Group Policy. Then select the GPO name you'd like to use.
Are either of these preferred or recommended? It seems they do work a bit differently... I currently use the second option to deploy printers, but I cannot go into the GPO that I deployed them to and modify it (it is blank.)
