I'be updated my Samba, rebuilding it with the printer patches from the samba ftp site. But now, while I can upload drivers, I can't assign a driver to a printer. Either with rpcclient or the Winy2k printer properties dialog. THe Winy2k gives an unable to save changes message. rpcclient $> enumdrivers [Windows NT x86] Printer Driver Info 1: Driver Name: [Lexmark Optra R plus] Printer Driver Info 1: Driver Name: [Lexmark Optra S 1625] Printer Driver Info 1: Driver Name: [Lexmark Optra R] rpcclient $> setdriver "actps" "Lexmark Optra R plus" SetPrinter call failed! result was NT_STATUS_UNSUCCESSFUL I've checked the permission on the tdb files and the printers subdirectory.
