Is it safe?

Yesterday I added a network print server device to my home network. How can I know that it is secure? Can I firewall it to prevent it from sending anything out to the internet? A few more details inside.

I bought this
no-brand print server device and hooked it up yesterday. It's working fine. I have no particular reason to distrust it, but OTOH, I'm not sure I should blindly trust it either. I think it can see all the activity on my home network if it chose to do so (router experts can correct me here if I'm wrong). If so, it could be potentially be harvesting passwords or cookies, etc. and sending them out somewhere on the internet.
I'm on a DSL connection and have a fairly crappy old westell modem/router with a custom UI added by my ISP. I don't think the modem has detailed controls that would allow me to firewall off this device from the internet. If it was doing something evil, it could probably forge packets anyway that would get past the firewall.
This is all most likely just excess paranoia and it's probably fine. But are there any steps I could take to be sure? Perhaps in the future I should think twice about buying no-name IP devices. Thanks in advance.
