According to http://wiki.documentfoundation.org/cgi_img_auth.php/6/6b/0102GS3-SettingUpLibO.odt you can use the operating system printer dialog on a Mac: "(Mac only) To use the standard Print dialogs for your operating system, deselect the Use LibreOffice dialogs option. When this option is selected, the Print dialogs supplied with LibreOffice will be used. This book uses the LibreOffice Print dialogs in illustrations." There should be an option to use the operating system printer dialog (e.g. kprinter, gtkprint) on Linux. For a bug report in a downstream distribution (Ubuntu) see: https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/47658
Yeah, and for bug report in Fedora see https://bugzilla.redhat.com/show_bug.cgi?id=476039 . I really should get it in one of these days...
support for native print dialog for gtk and gtk3 will be in 3.5 as experimental feature
