I'm trying to set up my printer. I have a Brother HL-2140 printer which has been working on my network. The printer is attached to my wife's Windows 7 PC on the network. The set up procedure on my Mac finds the "Windows" printer in Workgroup, dave-pc, Brother HL-2140. I have downloaded new drivers from Brother, CUPS drivers, and installed the new driver for this printer on my new Mac Mini. The printer doesn't work. Anyone have any ideas? I must be missing something.
