Is there a RenderFlag to set that will print all annotations including line annotations?

Using printDoc.RenderFlags = RenderFlags.FPDF_ANNOT does not seem to do this.

This is the actual document:
Actual.PNG (38kb) downloaded 1 time(s).

And this is the printed document:
Printed.PNG (19kb) downloaded 0 time(s).

The text annotations display but not the line annotations.

Thanks for your help on this.
