Print canvas pane only, not data pane from productstream

Hello, this might be a simple answer but I am having trouble with it, We preview our drawings in the Productstream canvas pane, and when you hit print it not only prints the drawing (eg. 6 page drawing) it also prints the Data Pane (eg. 3 page drawing) so the result is 9 pages coming out of the printer 3 of which go in the bin every time and its wasting ALOT of paper. How can I turn off printing the data pane? We do select print all rather than select which sheets we want, we do not have time to look at all the pages of the drawing and determine which ones are actual drawing sheets and which ones are data pane pages. We just want to print the drawings only. Thanks
