for this prodject you need two server's: Qlikview + nPrinting and Qlik Sense server
You can't publish QlikView dashboards in Qlik Sense. Olny export load script, but bashboards needed re created new
Qlik Sense server has self printing service. Of corse you can install Qlik Sense server nPrinting server and designer on same host, it does not make sense. Nprinting work's only with QlikView.
As an option, this equipment QS Server and nPrint S(D) + QlikView desktop
If you have any questions, ask
