------

void DirectXPage::GetPrintPreviewPage(Object^ sender, GetPreviewPageEventArgs^ e)
 {
     int PageCount =  e->PageNumber;
     Image^ previewPageTemp = ref new Image();
     BitmapImage^pImage =  ref new BitmapImage(ref new  Windows::Foundation::Uri("ms-appx:///", "Assets/print_1.png"));
     previewPageTemp->Width = 200;
     previewPageTemp->Height =100;
     previewPageTemp->Source = pImage;
     m_printDocument->SetPreviewPage(PageCount, previewPageTemp);

}

Just as a guess, I suspect that the image isn't loaded yet when you pass it to SetPreviewPage. Do you get the BitmapImage.ImageLoaded event before you call SetPreviewPage? Does the image show up if you preload it?
