Shared Computer

I just noticed that another shared computer showed up in the left bar. How can I delete the sharing privileges for this computer. I don't know who it is or what it is. The name is brneb76a9.

I did just install a brother color laser printer on my home network. Could it be that the printer is brneb76a9?

I tried disconnecting the printer but the sharing for brneb76a9 did not go away.

Thank you

After doing more research, I am pretty sure that this is the Brother printer on my network installed automatically using the Bonjour protocol.
