A thermal label printer that connects to a Mac via Bluetooth/Airprint?

I need a thermal label printer with wireless connectivity that doesn't use branded labels. I need to print shipping labels, but I'd also like to make round labels 1.5-2 inches (3.5-5 cm) in size.
I bought one that looked great, but it only works on a Mac via a USB cable. If anyone has one and really likes it, please recommend it. I'm really upset with my purchase, and I'm running out of the 8.5x11 sheets I used in my regular printer.
