Oh, and I totally forgot to say, what makes this more interesting is that when I print the page out from the web browser (IE 9.0), it prints perfectly. I'm not sure if that's because it's being printed straight out of RS rather than coming from the actual browser rendering. I'm thinking that's what's happening.

So because of this, I'm not sure that there is a fix to the browser rendering, since changing widths in my report definitions to make the browser look better would probably change widths in my report printouts to make them no longer look good.

Quite the quandary. I will look further into this.
