Printing PDF is very slow and spool file size 10X larger than Adobe reader

We are using Aspose.pdf.dll product version:17.3.0
1. When we print the pdf file using Adobe reader it took less than 8 seconds but Aspose taking almost 1 minute 20 seconds.
Aspose printing time is almost 10X longer time than Adobe.

2. When we print the pdf file using Adobe reader spool file size is 7.32MB but when we print Aspose pdf file spool size is 181 MB

3. The attached pdf file has only 253 pages and it took 1 minute 20s through Aspose but our most of the pdf files are more than 2000 pages.

Can you please suggest me what I am doing wrong.

Here is the code and pdf file.
Aspose.Pdf.License licensepdf = new Aspose.Pdf.License();
System.Drawing.Printing.PrinterSettings ps = new System.Drawing.Printing.PrinterSettings();
ps.PrinterName = PrinterName;
licensepdf.SetLicense(“Aspose.Pdf.lic”);
PdfViewer pdfViewer = new PdfViewer();
pdfViewer.BindPdf(Inputfilepath);
pdfViewer.PrinterJobName = “PRINT ENTIRE RETURN”;
pdfViewer.AutoResize = false;
pdfViewer.AutoRotate = true;

pdfViewer.RenderingOptions.SystemFontsNativeRendering = true;

//pdfViewer.PrintDocumentWithSettings(ps);

byte[] file = System.IO.File.ReadAllBytes(Inputfilepath);

using (MemoryStream memory = new MemoryStream(file))
{
pdfViewer.PrintLargePdf(memory);//, ps);

}
//pdfViewer.PrintDocument();
pdfViewer.Close();
