This is an example of how to add a Print Button to an Operator Window. The steps are;

var currentBitmapToPrint = null;
var printMarginPixel = 100;

function PrintControl(control) {
  PrintControl2(control, true, true)
}

function PrintControl2(control, landscape, autoScale) {
  var printPreviewDialog1 = new System.Windows.Forms.PrintPreviewDialog();
  currentBitmapToPrint = new System.Drawing.Bitmap(control.Width, control.Height);
  control.DrawToBitmap(currentBitmapToPrint, new System.Drawing.Rectangle(0, 0, control.Width, control.Height));

  var pd = new System.Drawing.Printing.PrintDocument();
  pd.DefaultPageSettings.Landscape = landscape;
  printPreviewDialog1.Document = pd;
	
  if (autoScale)
    pd.add_PrintPage(OnPrintPageAutoScale);
  else
    pd.add_PrintPage(OnPrintPage);
		
  printPreviewDialog1.ShowDialog();
}

function OnPrintPage(sender, e) {
  e.Graphics.DrawImage(currentBitmapToPrint, 100, 100);
}
	
function OnPrintPageAutoScale(sender, e) {	
  var newWidth = currentBitmapToPrint.Width * 100 / currentBitmapToPrint.HorizontalResolution;
  var newHeight = currentBitmapToPrint.Height * 100 / currentBitmapToPrint.VerticalResolution;
  var widthFactor = newWidth / e.MarginBounds.Width;
  var heightFactor = newHeight / e.MarginBounds.Height;

  if (widthFactor > 1 | heightFactor > 1) {
    if (widthFactor > heightFactor) {
      newWidth = newWidth / widthFactor;
      newHeight = newHeight / widthFactor;
    } else {
      newWidth = newWidth / heightFactor;
      newHeight = newHeight / heightFactor;
    }
  }
  e.Graphics.DrawImage(currentBitmapToPrint, printMarginPixel, printMarginPixel, newWidth, newHeight);
}
