Spacing Factor

To overcome this issue, try to reduce spacing between page elements proportionally. This is controlled by the SPACING_FACTOR parameter. By default, its value is 1.0 that means the spacing between report elements is exactly equal to the designed values. However, you can set any value between 0.0 and 1.0 to reduce the spacing and therefore make the whole page contents shorter. Keep reducing the parameter’s value until the report looks like expected.

Java

   import com.aspose.words.jasperreports.*;
   AWDocExporter exporter = new AWDocExporter();
   exporter.setParameter(AWExporterParameter.SPACING_FACTOR, 0.75);
   exporter.exportReport();
