打印表格

Question

我想打印整個頁面上我的形式，而是畫面看起來是這樣的：

它看起來非常小，這就是爲什麼我需要要在全整版

這裏印刷的形式是我的代碼：

private void button5_Click(object sender, EventArgs e) 
    { 
     CaptureScreen(); 
     printDocument1.Print(); 

    } 

    private Bitmap _memoryImage; 

    private void CaptureScreen() 
    { 
     // put into using construct because Graphics objects do not 
     // get automatically disposed when leaving method scope 
     using (var myGraphics = CreateGraphics()) 
     { 
      var s = Size; 
      _memoryImage = new Bitmap(s.Width, s.Height, myGraphics); 
      using (var memoryGraphics = Graphics.FromImage(_memoryImage)) 
      { 
       memoryGraphics.CopyFromScreen(Location.X, Location.Y, 0, 0, s); 
      } 
     } 
    } 

    private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) 
    { 



     var wScale = e.MarginBounds.Width/(float)_memoryImage.Width; 
     var hScale = e.MarginBounds.Height/(float)_memoryImage.Height; 

     // choose the smaller of the two scales 
     var scale = wScale < hScale ? wScale : hScale; 

     // apply scaling to the image 
     e.Graphics.ScaleTransform(scale, scale); 

     // print to default printer's page 
     e.Graphics.DrawImage(_memoryImage, 0, 0); 

    } 

你的幫助，將不勝感激

試試這個，讓您的形式的位圖：

Bitmap bm = new Bitmap(f1.Width, f1.Height); 
this.DrawToBitmap(bm, new Rectangle(f1.Location, f1.Size)); 

也許這就是問題所在！報告返回，如果它的工作！ 如果你想打印在橫向格式比你有你的位圖使用旋轉：

public Bitmap rotateInternalFunction(Bitmap bitmap) 
{ 
    bitmap.RotateFlip(RotateFlipType.Rotate90FlipNone); 
    return bitmap; 
}
