Getting error when printing to Local Printer

Question

My users want to be able to print a report I've designed in VS 2010, directly, rather than doing through the process of previewing the report. I've designed the report in VS 2010, using the report designer there, which has created a .rdlc file. I'm using the following MSDN walkthrough as an example, for my code:

http://msdn.microsoft.com/en-us/library/ms252091(v=VS.80).aspx

In my case, instead of data being in an XML file, I'm retrieving data from a SQL Server database, and I've got a .xsd file, etc. Plus I'm passing parameters to the report. It appears to be OK with my assigning the passed dataset and ReportParameters to the report. Here's a segment of the code, the last line is the line where the error occurs:

string deviceInfo =
"<DeviceInfo>" +
" <OutputFormat>EMF</OutputFormat>" +
" <PageWidth>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0.4in</MarginTop>" +
" <MarginLeft>0.5in</MarginLeft>" +
" <MarginRight>0.5in</MarginRight>" +
" <MarginBottom>0.4in</MarginBottom>" +
"</DeviceInfo>";
Warning[] warnings;
m_streams = new List<Stream>();
report.Render("Image", deviceInfo, CreateStream, out warnings);

And here's the error message I'm getting:

Microsoft.Reporting.WinForms.LocalProcessingException was unhandled
  Message=An error occurred during local report processing.

I came across this error as well and eventually tracked it down to a permission issue on creating the file stream within the CreateStream callback when running the render method. When creating the file stream it threw an access exception. Simply replaced the static filename with a unique temp name to resolve the issue:

    // Routine to provide to the report renderer, in order to save an image for each page of the report.
    private Stream CreateStream(string name, string fileNameExtension, Encoding encoding,
      string mimeType, bool willSeek)
    {            
        Stream stream = new FileStream(Path.GetTempFileName(), FileMode.Create);            
        m_streams.Add(stream);
        return stream;
    }
