[justtryingtoprint]

When trying to print wirelessly from my Android, I get the cryptic error "Xerox B210 (XRX9C934EAD518B)" and nothing prints. The test page prints fine. I chatted with Xerox support, but after being summarily disconnected by 3 agents, the 4th was kind enough to tell me I had to pay for a support contract to find out the secret meaning of the error message.

Griping aside - can anyone help me troubleshoot this or should I just chalk this up as a learning lesson and make this my last $150 Xerox-brand paperweight?
