PrintTask with Text Graphic

I used the tip in this thread to solve my disappearing text when printing issue:

However, as mentioned, clearing my attributes effectively cleared my text graphic. I'm now creating a new TextSymbol for each text graphic, but as I'm unable to control font weight and style, I followed first option in the following thread and created a new TextSymbol, inheriting from MarkerSymbol.

Now, my text symbols show up as point graphics when printed. When using a typical TextSymbol, the text prints fine. I'm sure I'm missing something when subclassing, I'm just not sure what. Any help would be greatly appreciated.

public class MyTextSymbol : MarkerSymbol     {          public MyTextSymbol()         {             TextSymbol textSymbol = new TextSymbol();             this.ControlTemplate = textSymbol.ControlTemplate;              this.FontFamily = new FontFamily("Arial");             this.FontSize = 12;             this.FontStyle = FontStyles.Normal;             this.FontWeight = FontWeights.Normal;             this.TextDecorations = null;         }          public String Text         {             get { return GetValue(TextProperty) as String; }             set { SetValue(TextProperty, value); }         }          /// <summary>         /// Identifies the <see cref="Text"/> dependency property.         /// </summary>         public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(String), typeof(MyTextSymbol), new PropertyMetadata(OnTextPropertyChanged));          private static void OnTextPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)         {             String text = e.NewValue as String;         }           public Double?

In order for a custom text symbol to work with the print task, it's necessary to implement IJsonSerializable and create a ToJson method in your class that builds the necessary JSON style information. I tried serializing the class to JSON with the built-in tools, but ran into issues because MarkerSymbol isn't marked for serialization. For now, I'm building the JSON string "by hand".
