Comment 2 for bug 1285788

I have Ubuntu 13.10 w/ LibreOffice 4.1.3.2, an HP Photosmart 6520 and HPLIP v 3.14.4. After selecting file/print/properties, in the new window the option for "Duplex" shows "Off". If I change that to "Long-Edge", then "OK", and then select "Properties" again, "Duplex" shows "Off" again. However, if I change "Off" to "<ignore>", then "OK", and then select "Properties" again, now "Duplex" shows "Long Edge" and the printer prints on both sides!
