Qt's printing dialog (as used, for example, by Iceweasel) does not infer the duplex setting from CUPS's printer options. This is a known bug in Qt, see https://bugs.kde.org/180051. A patch is available at http://bugsfiles.kde.org/attachment.cgi?id=41187. We've been using this pÃatch for ages, I include a revised version for 4.8.2.
