prnPaperOrientation (write-only)
Excel does not use the paper orientation setting from printer driver. If you need to change the paper orientation, use this property instead.
Set oPrinter = CreateObject("easyPDF.Printer.6")
Set oPrintJob = oPrinter.ExcelPrintJob
oPrintJob.PaperOrientation = PRN_PAPER_ORIENT_LANDSCAPE
oPrintJob.PrintOut "C:\input.vsd", "C:\output.pdf"
