That was introduced in PDF 1.7.
(So it will only work starting with Adobe Reader 8.)

Choose one of these options:
writer.addViewerPreference(PdfName.DUPLEX, PdfName.SIMPLEX);
writer.addViewerPreference(PdfName.DUPLEX, PdfName.DUPLEXFLIPSHORTEDGE);
writer.addViewerPreference(PdfName.DUPLEX, PdfName.DUPLEXFLIPLONGEDGE);
where writer is your PdfWriter instance.
For more info read the PDF Reference page 580:
"Duplex name (Optional; PDF 1.7) The paper handling option to use when
printing the file from the print dialog. The following values are valid:
Simplex - Print single-sided
DuplexFlipShortEdge - Duplex and flip on the short edge of the sheet
DuplexFlipLongEdge - Duplex and flip on the long edge of the sheet
Default value: none"
