Right, I understand how to do the landscape setting - it was already set to Landscape.
The problem is that when this report is generated in method, it's 6 pages total instead of shrunk into one, or instead of just shrinking the columns to fit (which would result in 2 pages).
In the Report Designer, I go the the Preview tab, and select the "Scale" button and select the "Fit to 1 Page Wide" option. I select the save icon from the main menu (not the save option in the lowest toolbar, which asks me to save the .prnx file locally). But when I tole back to the Designer tab, and then back to the Preview tab, the report is that same size as originally. The column shrinking didn't take.
Is there another option I should be using?
