Comment 4 for bug 486097

I experience the same issue. I figured out that after a reboot and after turning on the printer, it is in the paused status. If I login to the CUPS administration interface and from manage printers, I select the option to resume the printer, then it works ok.

So, after having the printer off and turning it on to print, I first have to resume it from the CUPS interface. Then, it works fine. There's no need to turn off the printer, unplug the USB interface, plug it in and turn on the printer.
