How to fix this XPSSerilizationExcpetion when printing a fixed Document?

Question

I have created a Base class that inherits from FixedDocument as so:

public class ReportViewBase : FixedDocument
{
...
}

then i am creating a Xaml file like this:

<rp:ReportViewBase x:Class="ReportingProto.CSTBeadLotTransReportView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:ui="clr-namespace:System.Windows.Documents;assembly=PresentationUI"
    xmlns:rp="clr-namespace:ReportingProto"
    x:Name="fdMain">
<PageContent>
        <FixedPage Width="816" Height="1056">
            <Grid>
                  <TextBlock Text="HI"/>
            </Grid>
        </FixedPage>
</PageContent>
</rp:ReportViewBase>

Then I had the document to the documentview like this:

<DocumentViewer Name="DocViewer" Document="{Binding Path=Document}"/>

Where Document is an instance of the ReportViewBase xaml defined above.

and when i click the print button on the documentviewer control and then pick an xps file to save to i get the exception below. Since my base class is a FixedDocument why does this not work?

Thanks for any help in advance!
