I am not able to attach the PDF file as it is 5MB & 15 MB- the file attachments to the support forum are limited to 2 MB

Hello,

Thanks for your inquiry!

For the 4.8MB file, I did meet the issue "System.NullReferenceException" when I print it, And I have logged it in our issue tracking system with the ticket SPIREPDF-4927 for further investigation.

We will let you know if there is any update. Sorry for the inconvenience caused.

For the 14.3MB file, I can print it after about 4 minutes. I am using the latest Spire.PDF 8.1.4 and printing it to Microsoft XPS Document Writer for testing. Do you mean that you need to optimize the printing speed? If not, please provide us with your project type(E.g. console app) and target framework (E.g. .net 5.0) for further investigate. Thanks in advance!

Sincerely,
Marcia
