Okay, If you have a trial version of both the client and the server, you can load both of them on your local workstation along with your QV app. As vishaggi pointed out, you can go to the Resource Library and find plenty of training materials on how to configure. We started out the same way and pretty much were able to self educate our way to making it work.
You have good amount of information at this place.
Just go through relevant tutorials for your requirements.
To give you a gist here: You need a valid Nprint server license installed and On -demand component installed seperately which come with the server. Using the On-demand extension buttons you can put the report buttons in your qlikview file and print them. Please go through that library and let us know if any further issues.
Everything you need to get started, including material around On-Demand reports is here: NPrinting 16 Training & Installation/Upgrade Information
There is also a training repository within that link and I suggest you download it.
Please consult the Resource Library for additional tutorials.
