Recommendations for Label Printer for Mac OSX?

Hi all,

Currently trying to narrow down the options for choosing a compatible label printer to be used in a primarily Mac OSX environment (50 or so MacBooks/iMacs and only about 10 windows 7 laptops). Not everyone will be using them, but only a few will be printing UPS/FedEx labels daily. In the past I was using a small Zebra printer hooked up to a desktop as a print server and it worked well. I wondering if I should stick with Zebra (though I am not sure if there are issues with drivers) or if anyone knows a better option that will work with OSX? Thoughts? Ideas? Suggestions?

Thanks!
