Remove empty fields from print friendly display?

[enginama]

I also found this code not working.
I took the main if statement and applied it to the standard template in export manager as below, all I added was the '{if $value!= ""}' & {/if}'
Hope this explanation helps someone.[/code]

Code:

<h1>{$form_name} - {$view_name}</h1>

{foreach from=$submissions item=submission name=row}
  {assign var=submission_id value=$submission.submission_id}
  <table cellpadding="2" cellspacing="0" width="100%"
    class="print_table one_item">
    {foreach from=$display_fields item=field_info}
      {assign var=col_name value=$field_info.col_name}
      {assign var=value value=$submission.$col_name}
     {if $value != ""}
      <tr>
        <th width="140">{$field_info.field_title}</th>
        <td>
          {smart_display_field form_id=$form_id view_id=$view_id
            submission_id=$submission_id field_info=$field_info
            field_types=$field_types settings=$settings value=$value}
        </td>
      </tr>
      {/if}
    {/foreach}
  </table>

  {if !$smarty.foreach.row.last}
    <div class="no_print"><i>- {$LANG.phrase_new_page} -</i></div>
    <br class="page_break" />
  {/if}

{/foreach}
