I have an older, but still very reliable Brother HL-5040 laser printer that continues to serve me well. Is there a way to print wirelessly through Bluetooth with this computer from my new iMac. I'm moving into a new office and don't want to run a USB cable all the way to the other end of the room. Do I just buy one of these Donger's on Ebay for $10? Or do I need something else? Or is this impossible and I need to buy a new printer? Thanks for your help.
