Network printer ?

[AlwaysUp]

We just got an HP photo printer for the home network. It has a ferrite thingy... (hope this isn't too technically put), but not much instruction on it. It says this will help reduce interferance with network printing. I don't know if I am supposed to wrap and snap it around the cable and leave it there or just swipe it a time or two on the cable. Does anyone know what I'm talking about and what to do?

Same devices are used on stereo components. I have one around my 5.1 home theater speakers where they connect to the amp. Put it on and leave it would be my choice.

Put a small loop in the network cable - about 2" in diameter - and snap the ferrite around the double side of the loop.

Thankyou both for your replies!
