What is your operating system?
What type of network connection are you trying to set up? Hooked up to a computer, or directly hooked into the Ethernet connection?
If its hooked up to a computer:
Right click the printer (in Control Panel > Printers )
Click "Sharing and Security"
And its self explanatory from there
fyi: The computer that its connected to
must be on to print if you connect it this way.
