I have a Xerox Phaser 4510 printer that works fine when I connected it by Ethernet in Ubuntu 12.04. However, when I switched to wifi, I cannot print even the test page though I can connect to the printer(ping is OK). By the way, it does work when I print on Windows 7, no matter I use wired or wireless network.
So did anyone experience this situation before? Is it caused by mis-configuration or just a bug of Ubuntu? Thanks for your help!
