C# 打印双面Excel

我正在使用此代码成功打印

我想做双面打印，但我不知道。有什么方向吗？

设置属性

您可以使用该属性检查打印机是否支持双面打印

或

你可以这样试试

worksheet.PrintOutEx(1,2, 1, false, Type.Missing, false, false, Type.Missing);

MyDuplexSettings.DuplexSettings ds = new MyDuplexSettings.DuplexSettings();

short status = 0;
string errorMessage = string.Empty;
status = ds.GetPrinterDuplex("<<Printer Name>>", out errorMessage);

if (status == 0)
{
//Console.WriteLine("Error occured. Error Message is : " + errorMessage);
//Some error occured, errorMessage is available in string errorMessage
}
else
{
 //Console.WriteLine("Current Duplex Setting is : " & status);
 //Call successfull, Current duplex flag is set to status
}

status = 2; //set duplex flag to 2
ds.SetPrinterDuplex("<<Printer Name>>", status, out errorMessage);
