The short answer is no.
The out-of-the-box ArcFM Silverlight viewer utilizes the server-side print solution provided from ESRI. That print solution will only accommodate simple fill, marker, text, and line symbols. The tracing components utilize custom symbols to highlight traces in the web map and that is why they do not appear on the preview or in the pdf output.
Thanks for responding Lance. I was pretty sure that was the answer I was going to get.
