Hello Brett

I'm guessing that you are using C#, since I can compile what you just sent.

I tried to convert a VBA script:
/*
* VB:
* Application.PrintOut FileName:="", Range:=wdPrintAllDocument, Item:= _
* wdPrintDocumentContent, Copies:=1, Pages:="", PageType:=wdPrintAllPages, _
* ManualDuplexPrint:=False, Collate:=True, Background:=True, PrintToFile:= _
* False, PrintZoomColumn:=0, PrintZoomRow:=0, PrintZoomPaperWidth:=0, _
* PrintZoomPaperHeight:=0
*/

To C#:
object Background = true;
object Append = false;
object Range = Word.WdPrintOutRange.wdPrintAllDocument;
object OutputFileName = "";
object From = Type.Missing;
object To = Type.Missing;
object Item = Word.WdPrintOutItem.wdPrintDocumentContent;
object Copies = 1;
object Pages = "";
object PageType = Word.WdPrintOutPages.wdPrintAllPages;
object PrintToFile = false;
object Collate = true;
object ActivePrinterMacGX = Type.Missing;
object ManualDuplexPrint = false;
object PrintZoomColumn = false;
object PrintZoomRow = false;
object PrintZoomPaperWidth = false;
object PrintZoomPaperHeight = false;
oDoc.PrintOut(ref Background, ref Append, ref Range, ref OutputFileName,
ref From, ref To, ref Item, ref Copies, ref Pages, ref PageType,
ref PrintToFile, ref Collate, ref ActivePrinterMacGX, ref ManualDuplexPrint,
ref PrintZoomColumn, ref PrintZoomRow, ref PrintZoomPaperWidth,
ref PrintZoomPaperHeight);

.. However you should know that I'm using Office 2003, so what version are
you using?
Try to populate all the arguments in the PrintOut method, to see if that
helps.

I even tried just printin the page in VBA, but it left out all arguments, so
I suppose that you could try typing in Type.Missing in all arguments, and
see what happens...

Hope this helps!
