Exporting a WEBI report to PDF to it size

Hi,

I am using WEB 4.1. I have created a report and exporting it to PDF format. But the when the PDF report is printed it real small and un readable. Where and what changes will I need to make in the WEBI report to be able to print the exported PDF report to reading visibility?

Thank you in Advance for all the help and thoughts!!
