PrintPreview and PDF in smartforms

Hi experts,

  I want to display the print preview of a smart form and from there i want to convert it to PDF.

If i set the Get OTF as 'X' then printpreview is not working ,only the pdf is creating.

I am using 'CONVERT_OTF' for conversion.

Is it possible to use PrintPreview and PDF.

I came to know through forum that we can achive this through 2 times calling the smartforms but i dont want to call smartforms 2 time.Is there any other way to achive this..

Please advice.

Thanks&Regards,

Karthik.
