Aspose.pdf 设置Color打印无效

        System.Drawing.Printing.PrinterSettings ps = new System.Drawing.Printing.PrinterSettings();
        ps.DefaultPageSettings.Color = false;
        ps.DefaultPageSettings.PrinterSettings.DefaultPageSettings.Color = false;
        Aspose.Pdf.Facades.PdfViewer viewer = new Aspose.Pdf.Facades.PdfViewer();
        viewer.PrintPageDialog = false;
        viewer.AutoResize = true;
        viewer.AutoRotate = true;
        viewer.BindPdf(fromPath);
        viewer.PrintDocumentWithSettings(ps);
        viewer.Close();

依然为彩色打印。
