samba - Oct 2009 - anyone using smbclient queue and cancel commands?

Hi,

I wonder if someone uses these commands successfully? Although I seem to
 login successfully to a windows box:

$:~> smbclient //reni/canon8500 -U user
Enter user's password:
Domain=[RENI] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]
smb: \> queue
smb: \>

I don't get any answer for this, knowing securely that there are jobs.

???
