Data cut off in print preview mode

I'm running 2.6.2 to create a basic report and for each report I create, it will display fine in layout mode and preview mode. However, in print preview mode, the data is cut off about a third down the page and the report is unusable. I've tried switching between fixed and auto modes and actually printing the report, but the data is cut off under any condition I can think of. I've looked at all the margins, and they seem to be correct (at .25 or .5in or 0).

Any ideas how I can fix this? I'm new to BIRT, so there may be something basic I'm missing, but I've mulled this over a while.
