Comment 1 for bug 1285788

I know there is the question of whether this is a Libre Office problem or HPLIP's problem, so I will just make one comment on that. All other software that I printed from, printed duplex with out a problem: Firefox, Thunderbird, Evince, Inkscape, Dia, Okular, (Even) Ninja IDE.
Work around is to "Export as PDF" in Libre Office and then open that document in any supporting program other than Libre Office for printing.
OS: Linux Mint 16 64-bit
