Setup a network printer via Ethernet on Airport Express
I have a Brother MFC-8480DN network-ready All-in-one, which connects to a network via Ethernet. The Airport Express has, in the past worked if I temporarily connect the printer via USB, and then go into the Airport utility (under Tiger - 10.4) and click the printer sharing tab, which is missing under Yosemite. The printer works while connected via USB, but when I did that earlier, the printer would quit before completing print jobs. However, after getting it working via Ethernet, it worked just fine. Under Yosemite, the Airport utility has an "Add WPS printer" menu item under "Base Station," which is greyed out, so I cannot use that method. Has anybody else set up an Ethernet network-ready printer using Airport Express under Yosemite (as, in effect, a print server on my existing wireless network)?
