1.1     ! foxr        1: \label{Print_Tricks}
        !             2: 
        !             3: When you print a LonCAPA resource, the XML of your resource is translated into
        !             4: LaTeX.  The LaTeX is then processed and turned into a PDF document which can 
        !             5: be displayed with your browser's Acrobat plugin and subsequently printed.
        !             6: 
        !             7: There are several problems that crop up both due to limitations in the XML to LaTeX
        !             8: translation and due to differences in the model used by web browsers to render
        !             9: HTML and LaTeX to compose print pages.  This document provides information
        !            10: about some of these problems and, where possible, solutions, and tricks to work 
        !            11: around them.  If you have a printing trick or a problem and would like to report 
        !            12: it, please go to  http://bugs.lon-capa.org and register a bug report.
        !            13: 
        !            14: General information about printing within LonCAPA is also available: 
        !            15: \ref{Print_Resource}
        !            16: 
        !            17: \section{\&prettyprint and \&dollarformat look ugly}
        !            18: To make these two functions work correctly within the print translator, it is
        !            19: necessary to wrap them within a <DISPLAY> tag.  For example:
        !            20: 
        !            21: \begin{verbatim}
        !            22: <p>
        !            23: If I had <display>&dollarformat(100)</display>
        !            24: </p>
        !            25: \end{verbatim}
        !            26: 
        !            27: Note that the <display> tags must be tightly wrapped around the function call or
        !            28: you will get a syntax error in web presentation mode.
        !            29: 
        !            30: 
        !            31: \section{Image placement and alignment is wrong}
        !            32: Unfortunately this is due to a large difference between the LaTeX and HTML page
        !            33: layout model.  In HTML images are placed exactly where you ask them to be placed.  
        !            34: In LaTeX, images are considered {\em floats}, which LaTeX will place for you.
        !            35: There are a few print options you can try to place images approximately where you 
        !            36: want them relative to sorrounding text \ref{Print_Options}.
        !            37: 
        !            38: \section{Variables with tags don't print correctly}
        !            39: If a variable contains XML, in general it is necessary to force the XML parser
        !            40: to make a pass over the contents of the contents of the variable prior to rendering
        !            41: the section of the resource that contains that substitution.  For example:
        !            42: 
        !            43: \begin{verbatim}
        !            44: 
        !            45: \end{verbatim}
        !            46: 
        !            47: 
        !            48:
