Dillep,

Do you mean that the image doesn't appear in the Preview dialog?

To resolve the problem, please try the following code:
+-----------------+
PrintDocument _printDocument;

private void InitClass( )
{
...
_printDocument = new PrintDocument();
_printDocument.PrintPage += new PrintPageEventHandler(_printDocument_PrintPage);
...
}
private void _printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
RasterImage image = rasterImageViewer1.Image;

RasterImagePrinter printer = new RasterImagePrinter();
printer.UseDpi = rasterImageViewer1.UseDpi;
printer.Print(image, image.Page, e);
}

private void _menuItemFilePrintPreview_Click(object sender, EventArgs e)
{
if(_printDocument != null)
{
try
{
PrintPreviewDialog dlg = new PrintPreviewDialog();
dlg.Document = _printDocument;
dlg.ShowDialog(this);
}
catch { }
}
}
+-----------------+

Please try the same issue using the above code and let me know how it goes.

Thanks,
