Hello,
Thanks for your inquiry.
To help us locate the issue quickly, I need some details. No file printed means no real output file or the blank paper? If there is only one page and you print the document by control like this.pdfDocumentViewer1.Print(), the result will turn blank. We suggest you trying the latest hotfix Spire.PDFViewer Pack(Hotfix) Version:2.12.38 which works ok as we have no plan to update the free version and all the fixes and new features are implemented in the commercial version,
Sincerely,
Jane
