Did you tried enabling visual printing setting for report and printing it as a regular report?
I have to say that control added for on screen data analyzing. This is a third party control and not compatible with .net’s printing mechanism and does not support some features properly like pagination, page fitting, etc. It has own printing mechanism but it is also not compatible with .net’s printing so it only prints the control itself. I tried to make it useful by processing it as an image with visual printing setting… I hope that helps.
