You need Qlikview Desktop installed on your PC and licensed, then just go and Copy (Ctrl-C) object and Ctrl-V on ppt. When you switch to presentation mode Qlikview functions will work on the object while you are in ppt, you can also copy-paste a filter and filter your numbers while presenting, etc.
Right click your mouse on the chart and select Print -> A new tab is opened and copy the chart by right clicking the chart in new tab, select Copy and Paste it in the PowerPoint file. This way you can copy chart image.
There is a print... menu entry in AccesPoint (if printing is enabled for your document, that is - see QMC settings). But as fas as I can see, there isn't any in WebView in QlikView Desktop. Of course, that may depend on the IE version that's installed on your PC.
I was taken by surprise as well. My previous answer was deleted because it was incorrectly based on the WebView features.
