The recipients are access to the Qlikview application from the web and as you know the selections they make, don't affect the original application in the server side. My question is, is it possible for the recipients to issue reports based on their current selection from the access point?? if it is, what would be the role of NPrinting server?
I would also suggest downloading the nprinting training environment as well - it has actual applications and working examples that are extremely helpful
also refer to the reference inforamtion on the NPrinting community, located at QlikView NPrinting
