Can't configure 2330dn in a network

Hi,

I'm new in the networking and I want to configure a network. What I have is a reception PC with a Dell 2330dn connected and some workstations that want to connect to it.

Reception:

The printer works well printing in USB001 and I configured it to be shared. I configure my domain also to share printers (Network and Sharing Center). I made a exception in the firewall.

Workstations:

I go to Devices and Printers and search it in the Network printers. It doesn't appear. I have re-installes the drivers and I tried to print in the port "Dell Enhanced TCP/IP port" but it doesn't work.

I have tried a lot of different solutions, any suggestion??

Best regards,

Sergio
