When I run reports that are for board or other external audiences, I like them to look professional. There is no way to adjust the margins for reports. The left margin defaults to something around 1/4 inch. My current solution is to print each report to Excel and then format. Depending on how much data is going on the report, I would likely set the margin at 0.5 or 1.0 inches. Sometimes I even like to center the report on the page. My goal is to avoid having to print to Excel to further process.
