Hi.

When I use Libreoffice on Mageia 4 KDE and Cauldron KDE there are problems printing double sided pages on a HP Photosmart 7520 (I do not know if the problem appears even on other kind of printers).

To print I go on Print -> Property -> select A4 AutoDuplex and Long Edge -> OK (The printer parameter Device -> Duplexer Installed is set to Installed)
If I click an other time on Property, all parameters are correct except Front/Rear which is always OFF
Obviously the printer print always in single page mode.

To skip the problem I modified the default printer parameter to A4 AutoDuplex and Long Edge and use the <Ignore> option of Front/Rear parameter.

This problem affect many distro except Fedora 20, may be it can be a good source to found a patch for the problem.


Bye Bye, Moreno
