what dongle do I need to connect my MacbookAir to my printer?
I am having trouble printing wirelessly, and would like to hook up to my printer directly. My printer is a Brother HL-L2360DW. I tried to buy the dongle at the Apple store, but they no longer sell them, and the representative told me to buy it on Amazon. I just don't know which one to order - there are many choices. Please let me know which one to order. Thank you.
MacBook Air, OS X Yosemite (10.10.5)
