问以编程方式更改PCL6打印机上的双面打印设置(对照默认值)

EN

Word.Application wordapplication = new Word.Application
{
    Visible = false
};

Word.Document wordDocument = wordapplication.Documents.Add(filePathWithName);
wordapplication.ActivePrinter = printer;
Range range = wordapplication.ActiveDocument.Range(
                        wordapplication.ActiveDocument.Content.Start, 
                        wordapplication.ActiveDocument.Content.End);

//wordapplication.ActiveDocument.Fields.Add(range, WdFieldType.wdFieldPrint, "&l0S", false);     //This also didn't work, people says it works for PCL5 only
wordapplication.ActiveDocument.PrintOut();    ///ManualDuplexPrint: false also didn't work
wordDocument.Close(SaveChanges: false);
wordDocument = null;

// Make sure all of the documents are gone from the queue
while (wordapplication.BackgroundPrintingStatus > 0)
{
   System.Threading.Thread.Sleep(250);
}

wordapplication.Quit(SaveChanges: false);
wordapplication = null;
