N-printing is not available for QlikSense yet but it is in the pipeline, watch this space
There is however an extension on Qlik Branch that allows you to save to PDFs,
Other than that you are probably looking at publisher style functionality on the sense server.
There will be some extended reporting capabilities in Qlik Sense with the 2.0 release which is due this summer. It will not have the full capabilities of NPrinting but will be an upgrade of what is there in Sense today. Full static reporting capabilities is also on the road map and should be released in upcoming versions.
As Toni mentioned, there is an extension out in Branch which can also be used.
Hope this helps.
