Silent Print a Document in a Windows Service

Question

Hello,

This a tricky question, I'm using control PdfDocumentView to load an document and print directly to a printer ...

Code:

            PdfDocumentView pdfDocView = new PdfDocumentView();
            pdfDocView.Load(pathGeneratedPdf);
            pdfDocView.Print("name of printer");

This code is used in a Console Application , and runs fine.

If I try to run in an Windows Service, "access is denied" is showed. Is there a way to invoke Printing a Pdf in a
Windows Service ?

Best Regards,

João Guedes

Hi João Guedes, 
 
Printing a file using System.Drawing.Printing is not supported in Windows Service. Since we are using System.Drawing.Printing namespace to print a PDF document using PdfDocumentView, it is not possible to achieve the same in Windows Service. 
The following MSDN link explains the problems occurred while printing a file using Windows Service.https://msdn.microsoft.com/en-us/library/system.drawing.printing.aspx 
"Classes within the System.Drawing.Printing namespace are not supported for use within a Windows service or ASP.NET application or service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions."As per the documentation, the System.Drawing.Printing namespace is not encouraged to be used within a Windows Service.Please let us know if you need any other assistance.
