Print only selected records in the checkbox

I have the following table, but I'm not sure how to use the checkbox, how do I print only the selected checkboxes?

And as he is inside the table he is appearing in the print, how to make it not appear too.

<table class='datatable table table-hover table-bordered table-responsiv'>
        <input type="button" name="imprimir" value="Imprimir" onclick="window.print();">
       <thead>
         <tr>
            <th align='center'><font size=1>#</font></th>
            <th align='center'><font size=1>Chamado</font></th>
            <th align='center'><font size=1>Problema</font></th>
            <th align='center'><font size=1>Descricao</font></th>
            <th align='center'><font size=1>Contato</font></th>
            <th align='center'><font size=1>Data</font></th>
            <th align='center'><font size=1>Loja</font></th>
            <th align='center'><font size=1>Setor</font></th>
            <th align='center'><font size=1>Aberto</font></th>
            <th align='center'><font size=1>Status</font></th>
            <th align='center'><font size=1>Farol</th>
         </tr>
        </thead>
      <?php
