Brother 2170W. I've tried setting up through USB connected directly to the printer, and connecting via ethernet directly to the router (Airport Extreme). I get it set up and it seems to be working, but then it won't work the next day. It has a static IP address and when I connect to the settings page on my browser, I can access it and print a test page. But when I print an actual job it times out and says printer offline. I know the printer in online and connected to the network, right? I couldn't print a test page remotely from my MBP unless that was functioning. Why won't it print my other jobs?
