Printer Properties Pro - Printer Migration Utility
* The Printer Migration Utility copies or moves NDPS, iPrint or Novell Queue
printers from eDirectory to Active Directory or to any Windows print server.
It also "re-maps" the end users workstation printers to point to the new
printers in Active Directory or on Windows servers. Completely automated
eDir to AD printer migration! Your users will not notice a thing.
