Unknown Device on Mac

I'm in the process of setting up my new mac and in the sidebar under shared I have -

Desktop - khqt872

I don't have any other pc's connected so what is it. It's also under devices- my MacBook - Network

Someone using your wifi???

I kept having a bonjour item show-up on my Mac. After going around the world to identify it, I finally confirmed it was my printer.

My guess is also that it's going to be your printer.
