[Samba] samba3 print server : ghost printer problem

[FM]

Hello,
I configure my PDc as print server.
With cups, I configure 3 printers (names : print1 print2 and prinnt3). 
After that I saw the error in the last printer's name. So I delete 
prinnt3 and create print3).

But if I connect to my print server (using Windows), I have 4 printers : 
print1 -3 and prinnt3

I restart cups and reload smb daemon several times but the ghost is 
still there.

I have the prob for 2 days now so I supposed that it's not a network 
neighborhood prob anymore ?
