PdfViewer printing blank pages

[Larry Marshall]

The following method prints three blank pages for a three-page PDF file which exists on disk. It does not throw an error.

public static void PrintPdf(string pdfFileName, string printerName)

{

    PdfViewerControl viewer = new PdfViewerControl();

    viewer.Load(pdfFileName);

    PrintDocument document = viewer.PrintDocument;

    document.PrinterSettings.PrinterName = printerName.TrimEnd();

    document.Print();

}

I'd appreciate any help in determining why.

Or better yet, is it possible to extract the libraries I need rather than install the entire suite?

I noticed in your sample you're using 15.1.0.33. I used 37. Also, I have a Community License for the Enterprise Edition. 

I installed the Enterpise exe on my D disk (System disk on C is a small SSD). I am getting compilation errors. Can you help me resolve them?

Hi Larry,
 
Sorry for the Inconvenience caused.

On analyzing further on the mentioned stack trace details, we found that these errors may occur due to assembly conflicts with the Nuget packages installed. We have modified the project.json file of the sample to overcome this issue and attached the sample for your reference. Please find the sample from the below link.

Thanks, I can compile and run successfully now with your code.

However, when I substitute my PDF for your Barcode.pdf, I see (don't see) the same results as I originally reported: blank output.

Perhaps you could try it?

Hi.
We have encountered a problem similar to the one described above.
We limited the problem only to PDFs created by Lexmark scanners.
Optimizing the pdf file created by lexmark scanner with adobe acrobat professional files work. We did not find a similar feature in Essential Pdf.

Are you aware of this problem?
Do you have any solutions?

Hi Davide,

Thank you for contacting Syncfusion support.

If you are facing the issue “Blank pages are obtained while printing the PDF document using PDF Viewer”, we have integrated the Pdfium rendering engine in to our PDF viewer control and this issue was not reproduced using the same. The support for Pdfium rendering engine is available from the Essential studio version 16.1.0.24. Kindly upgrade to our latest essential studio version and it is available for download under the following link.

https://www.syncfusion.com/forums/137209/essential-studio-2018-volume-1-service-pack-release-v16-1-0-37-available-for-download  

Please find the KB and a simple sample illustrating how to use Pdfium with PdfViewer for your reference in the following link.
