Hi SilverD442,
You can edit the view: "product / show_default" in HikaShop > Display > Views
And at the top of this file, try to add:
<?php if(JRequest::getString('tmpl','view')=='component'){?>
<!-- You logo -->
<div class="product_view_print"><img src="" alt="Your LOGO"/></div>
<?php }else{ ?>
<a title="<?php echo JText::_('HIKA_PRINT');?>" class="modal" rel="{handler: 'iframe', size: {x: 760, y: 480}}" href="<?php echo JURI::current()."/tmpl-component"; ?>">
<span class="icon-32-print" title="<?php echo JText::_('HIKA_PRINT'); ?>">
</span>
<?php echo JText::_('HIKA_PRINT'); ?>
</a>
<?php } ?>
