If you are unable to export the report as a PDF please check which version of Internet Explorer (IE) you are using on your ePay server.
Please Note: This will be the machine running the ePay service.
For help identifying your ePay server please see the related article: How can I locate my ePay server?
The export function in ePay is restricted on somes versions of Internet Explorer as it uses IE components that are only compatible in IE 9 or below.
This means if you are running Internet Explorer 10 or higher you will be unable to use the export to PDF function. To resolve this issue you would be required to downgrade your Internet Explorer version.
