2755 root.lpadmin

There is no file W32X86/SETUP32.DLL.  Samba seems want to create it
("Can't open new file [W32X86/SETUP32.DLL]"); according to the
permissions, it definitely can.  The permissions of the files in
/var/lib/samba/printers are always <someuser>.lpadmin 664 and 775 the
directories.  I enforce them using this smb.conf entry:

| [print$]
|    comment = Printer Drivers
|    path = /var/lib/samba/printers
|    force group          = lpadmin
|    create mask          = 0664
|    force create mode    = 0664
|    directory mask       = 2775
|    force directory mode = 2775
|    read only = yes
|    write list = root, @lpadmin
|    guest ok = yes

Installing the first printer driver worked fine with this setup.
