And what's wrong with System.Windows.Media.DrawingContext.DrawText?

Please see:

5'ed - it will get the job done as long as OP is willing to handle wrapping himself :)

You could achieve this through the FlowDocument:

XML

<FlowDocumentReader>
    <FlowDocument
        Name="flowDocument"
        ColumnWidth="400" FontSize="14" FontFamily="Georgia">
        <Paragraph>
            <Grid>
                <Rectangle Fill="Red" Width="200" Height="100"/>
                <TextBlock Text="Hello World!" HorizontalAlignment="Center" VerticalAlignment="Center"/>
            </Grid>
        </Paragraph>
    </FlowDocument>
</FlowDocumentReader>

The code behind would then look like:

C#

public static void SaveAsXps(string path, FlowDocument document)
{
    using (var package = Package.Open(path, FileMode.Create))
    {
        using (var xpsDocument = new XpsDocument(package, System.IO.Packaging.CompressionOption.Maximum))
        {
            var xpsSerializationManager = new XpsSerializationManager(new XpsPackagingPolicy(xpsDocument), false);
            var documentPaginator = ((IDocumentPaginatorSource)document).DocumentPaginator;
            xpsSerializationManager.SaveAsXaml(documentPaginator);
        }
    }
}

And the calling code:

SaveAsXps("temp.xps", flowDocument);

Just another way to do it. I personally prefer keeping the UI in XAML.
You'll need to add a reference to ReachFramework.dll for this to work.

Why not use a TextBlock[^].

Remember to set the TextBlock.TextWrapping[^] to true.

Have a look at VisualsToXpsDocument[^], it provides methods for writing visual objects to xps documents.
