Printing PDF from RDLC changes font



I am printing from a RDLC report and the font selected, Segoe UI, is actually printing in Times New Roman.  I've attached some screenshots to illustrate the issue.


The pdfViewer variable is a SfPdfViewerControl object.


This is the code I use to generate the PDF:

            Assembly assembly = typeof(ResultsPage).GetTypeInfo().Assembly;

            Stream reportStream = assembly.GetManifestResourceStream("Report.rdlc");

            ReportWriter writer = new ReportWriter();

            writer.ReportProcessingMode = Syncfusion.ReportWriter.ProcessingMode.Local;


            writer.DataSources.Add(new ReportDataSource { Name = "Data", Value = PopulateData() });



            MemoryStream stream = new MemoryStream();

            writer.Save(stream, WriterFormat.PDF);


            // A zero length stream just causes the LoadDocument to hang.

            if (stream.Length > 0)


                await pdfViewer.LoadDocumentAsync(new PdfLoadedDocument(stream));



This is the code I use to print the pdf:



Any idea how to get my print outs to actually print in the Segoe UI font I have selected instead of Times New Roman?


Thank you,

Hi Michael, 
As UWP platform does not provide access to the installed font data in the system, Unicode fonts such as “Segoe UI” cannot be embedded directly in exported PDF document. Hence need to add required Unicode font files as an embedded resource to the document for the display and print of text using the appropriate font. The Unicode font streams need to be added to the Report Writer’s PDF Fonts collection to export report as PDF format with Unicode fonts as shown in the below code snippet.  

writer.PDFFonts = new Dictionary<stringStream>(StringComparer.OrdinalIgnoreCase);  
writer.PDFFonts.Add("Segoe UI", assembly.GetManifestResourceStream("UWPwriterSample.Assets.Segoe_UI.ttf"));  
Please find the sample attached in the below link which illustrates how to add required Unicode font files as an embedded resource to the application. 
And also attached printed output document in OXPS format which contains Segoe UI font printed using PdfViewer and it displays as Segoe UI font. 
Please let me know if you have any concerns.

Hi Michael, 

We checked the reported issue and we were unable to reproduce it. Is it possible for you to share us the report and the font file, as it will be helpful for us to validate it from our end.
