Traditionally, Windows clients were hosted from seperate print servers running Novell's NDPS and the third party Pcounter software.  This required that the logs and quotas be syncronized.  Starting in 2009, we moved to use Samba to convert the native Microsoft SMB/RPC print requests into a form that WolfPrint can use.
