Hi Janet.....
This happened to me in a statement I was editing in AR.... My problem (with a text box in the statement showing background colour in my print preview, then not printing the background colour when I printed it ended up being something to do with a box I had ticked off in the Maintain Specifications/Statement Editing area. It was a tick box on one of the fields when I was attempting to change the background colour. I think it had the word transparent in it. Hope this helps in any way.
