 Unfortunately this is due to a large difference between the LaTeX and HTML page
 layout model.  In HTML images are placed exactly where you ask them to be placed.  
 In LaTeX, images are considered {\em floats}, which LaTeX will place for you.
 There are a few print options you can try to place images approximately where you 
 want them relative to sorrounding text \ref{Print_Options}.

+\emph{Variables with tags don't print correctly}
+
 If a variable contains XML, in general it is necessary to force the XML parser
 to make a pass over the contents of the contents of the variable prior to rendering
 the section of the resource that contains that substitution.  For example:
 
 \begin{verbatim}
-
+<problem>
+<script type="loncapa/perl">
+$a = &xmlparse('<br />');
+</script>
+<startouttext />
+<p>This is a break <display>$a</display> and then some more text</p>
+<endouttext />
+</problem>
 \end{verbatim}
 
+Without the xmlparse call and the display tag bracketing the variable, this
+problem will display on the web just fine, but print incorrectly.
