I'm trying to install a DELL 3115cn with windows wizard. But when I insert the URL of the printer I receive this error message:

 

"Windows cannot connect to the printer. either the printer name was typed incorrecty, or the specified printer has lost its connection to the server"

 

The printer is plug correctly in the LAN with the address 192.168.242.21, i can access to the web pages of the printer. IN the URL field I'm using: http://192.168.242.21 or 192.168.242.21 but the result it's the same.

 

Any idea
