smartform convertion in PDF.

here requirement is PO printout should convert in PDF and it should go to vendor mail address.

our functional consultant asign the form in nace. its working properly ( mail is going to vendor in PDF format). but the PDF size is 44%. they are asking it should be 100% and portrait format.

i have no idea what to do so that i can get the PDF in portrait and 100%. in smartform page format is portrait only.
