I feel like MS is in denial about the misterious gray block on the print page. I've explained it in other threads and here we are. The cause of this problem which makes the whole reporting useless is simply a bug. The logic that crafts the content to be printed fails to exclude the left navigation pane when visible. It's an easy fix but hard to find.
So do the following to optimize your print outs:
1- Change the Page Type to Letter
2- Re-adjust all visuals and make sure nothing is over-floating or overboard.
3- Hide the left navigation bar if it's visible
4- In preview, remove any margins.
This should do the trick; however, there is still going to be a dark line across which we can only hope to disguise as stationary mishap.
Thanks,
