The parameter is used to define the absolute path to a file containing a mapping of Windows NT printer driver names to OS/2 printer driver names. The format is: <nt driver name> = <os2 driver name>.<device name> For example, a valid entry using the HP LaserJet 5 printer driver would appear as HP LaserJet 5L = LASERJET.HP LaserJet 5L. The need for the file is due to the printer driver namespace problem described in the chapter on Classical Printing in the Samba3-HOWTO book. For more details on OS/2 clients, please refer to chapter on other clients in the Samba3-HOWTO book.
