There is a new version of SavaPage available.
https://wiki.savapage.org/doku.php?id=release_notes:release_notes_1.2.0
integration of a previous version of SavaPage in Nethserver is available as a Howto in our wiki:
https://wiki.nethserver.org/doku.php?id=userguide:savapage
Or as a community module by @mrmarkuz:
https://wiki.nethserver.org/doku.php?id=savapagemodule
Can we do a joined effort to update the howto and the module?
For detailed info you can always ping @rijkr, the main developer of the SavaPage project.
