duplex printing excel sheet

[mtacki]

Hi everyone...

I'm using this code to print an execl sheet from within my program...

Dim printout As String = "c:\test.xls"

workbook = APP.Workbooks.Open("c:\test.xls")
APP.ActiveWorkbook.PrintOut(Copies:=1, Collate:=True)
APP.ActiveWorkbook.Close(False, "c:\test.xls")
APP.Quit()



The only thing, I can't find anything about is how to use duplex printing...
Can anyone help me with that ??

Thanks in advance !!

Cheers,

mtacki
