Microsoft changed the way printers are installed with update KB3170455 (MS16-087). Now, for printers to be installed using group policy, the print driver must be set as true under packaged in Print Management. Some vendors have not updated their drivers to make them packaged, but there is a way to force a package to be packaged.
Open regedit and go to HKLM\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows *** (choose version)\Drivers\Version-3\**DriverName**
Set the attribute PrinterDriverAttributes to 1 and restart the print spooler on the server. The driver will now show true as packaged and will install using GPO.
