Qlik NPrinting is the newer version release 17.x this one works with View and Sense with a web based front end. Its the way Qlik are moving with this product but there are experience and usuablilty issues they are still working through from my experience.
QlikView NPrinting only works with View but is a much more mature product in terms of functionality and performance.
Depends where you are with your Qlik Deployment. If you are on or moving to Sense then look at the new one with the Caveat that its still got some work to do on it to bring it up to speed.
Also both versions work with Server editions of View/Sense so you need that setup first.
