Looking for HP Color Laserjet 2550n CD

Hi,

I bought my printer about a year ago and I received an installation CD with
it that had a software whose name I don't remember. But it allowed to see
the printer status (including the toners' status).
Unfortunately, I moved since then and I've lost that installation CD. I've
checked on the HP website and all I can find are the drivers. I can't find
that software.
So, if any of you has that CD or can tell me where I can find it, I'd be
very grateful.

Thanks

Fred

P.S. I'm not sure that this is an appropriate group so sorry if it's not
