Slow printing speed of PDF document

The print speed of PDF file based on the The previous source as shown below was normal.
But the printing speed of PDF file on the new source is significanty slow.
The differnece between two sources are the addition of Aspose.Pdf.Facades in the new source.
Please advise why this happens and any solutions to improve?
Thanks

Thanks for contacting support.

Would you please share a sample input document, which you are using along with shared code snippet. We will test the scenario in our environment and address it accordingly.

Hello, has any progress been made on this issue. I have the same problem, viewer.PrintDocumentWithSettings takes around a minute to print a small pdf document. We are hoping to use this product to print several pdf documents a day and this performance issue is a hang up.

Thanks,
Paul

Thank you for contacting support.

Please note that the issue was not logged in our issue management system owing to missing resources for reproducing it. Would you please share a narrowed down sample application reproducing this issue, along with all necessary resources so that we may try to reproduce and investigate it in our environment to help you out.

Hello, attached is a simple c# console application that prints a single page pdf document. We have a requirement that the application be able to print to any network printer (we have over 200), so this application will reside on a server and supply the name of the printer in the format \<printer name>.

When running the sample app, it takes approximately 70 seconds for the single page pdf to print.

Thank you for your help.
