i want to generate the report

In my ultra gird i have 530 columns. i have used ultraGridDocumentExporter1.Export(Gird.GridControl, report); to export the grid then i used

pages = report.Generate(); which give me all the data in one single page. when i used

this.ultraPrintPreviewDialog1.ShowDialog(this);

this show me a preview of grid with very small rows and colums and it is not readable.

How can generate multiple pages with report.Generate(); so that i can get multiple pages with fixed number of columns with good font size .

Thanks.
