al momento ho seguito questa strada.

quindi una cosa del genere:
codice:
<script>
    function setPrintOpts(componente, valore) {
        componente.each(function () {
            $(this).val(valore);
        });
    }
</script>
<form action="<?php echo BASE_URL_CRONOS; ?>admin/dispatch_print_bs.php" method="get" target="_blank">
    <div class="pull-left" style="margin-right: 20px;">
        <button type="submit" name="coll" class="btn btn-default-black" value="<?php echo $collezione; ?>">
            <span class="glyphicon glyphicon glyphicon-print"></span> Stampa
        </button>
        <input name="pt" type="radio" value="230" onchange="setPrintOpts($('input[type=radio][name=pt]:checked'), $(this).val());"> A3
        <input name="pt" type="radio" value="150" onchange="setPrintOpts($('input[type=radio][name=pt]:checked'), $(this).val());" checked> A4
    </div>
    <div class="pull-left">
        <input name="qta_tipo" type="radio" value="pz" onchange="setPrintOpts($('input[type=radio][name=qta_tipo]:checked'), $(this).val());" checked> Pz
        <input name="qta_tipo" type="radio" value="perc" onchange="setPrintOpts($('input[type=radio][name=qta_tipo]:checked'), $(this).val());"> %
    </div>
    <div class="clearfix"></div>
</form>
<?php foreach ($query as $a): ?>
             
                <form action="<?php echo BASE_URL_CRONOS; ?>admin/dispatch_print_bs.php" method="get" target="_blank">
                    <?php echo $a['bs_fornitore_descrizione'] . ' - ' . $a['ord'] . ' PZ'; ?> - 
                    <div class="hidden">
                        <div class="pull-left" style="margin-right: 20px;">
                            <button type="submit" name="coll" class="btn btn-default-black" value="<?php echo $collezione; ?>">
                                <span class="glyphicon glyphicon glyphicon-print"></span> Stampa
                            </button>
                            <input name="pt" type="radio" value="230"> A3
                            <input name="pt" type="radio" value="150" checked> A4
                        </div>
                        <div class="pull-left">
                            <input name="qta_tipo" type="radio" value="pz" checked> Pz
                            <input name="qta_tipo" type="radio" value="perc"> %
                        </div>
                        <div class="clearfix"></div>
                    </div>
                    <button type="submit" name="coll" class="btn btn-sm btn-default-black" value="<?php echo $collezione; ?>">
                        <span class="glyphicon glyphicon glyphicon-print"></span> Stampa
                    </button>
                    <input type="hidden" name="forn" value="<?php echo $a['bs_fornitore_codice']; ?>">
                </form>
<?php endforeach; ?>
ho fatto varie e prove e sembra funzionare tutto.
