[Plugin: PDF24 Article To PDF] How-to include Custom Fields in PDF?

Any replies? Just to provide a more detailed explanation of my problem:

Added custom fields by “get” to my posts (single.php and the loop) and a category-based menu page.

<?php the_content(); ?>
  <ul>
    <?php if ( get('CUSTOM_FIELD_NAME1',TRUE) ) {
     echo "<li>Custom Field Name1: ", get('CUSTOM_FIELD_NAME1'), "</li>";
     }
    ?>
    <?php if ( get('CUSTOM_FIELD_NAME2',TRUE) ) {
     echo "<li>Custom Field Name2: ", get('CUSTOM_FIELD_NAME2'), "</li>";
     }
    ?>
  </ul>
</div><!-- .entry-content -->

I want to create a pdf of the category-based menu including the fields. How-to?
