Oracle Application Express Listener PDF Report We need our reports to be available in PDF format on our Oracle 11g, APEX:4.2.6

Followed this tutorial and selected "Oracle APEX Listener".

But the generated PDF report is empty.

We are using EPG.

Do we have to install/configure anything else other than the mentioned tutorial.
Here's an answer from an Oracle Employee on Oracle Community:

"The problem is when the default page size is set to A4, which translates into points with decimals when rendering the PDF. Please, change the Units to Points, and round up your page width and height."
