Add Line Item Properties to Packing Slip or Order Confirmation

When a merchant uses line item properties which are the extra details about specific items in an order you can add this snippet of code somewhere within the Packing Slip, Order Printer or Order Confirmation to display that property.   The line item property is different from Custom Attributes (which is the extra detail about the order shown on the right side) and different from Order Notes.   Line Item Properties are usually added by apps or custom code and are specific to the line item. 



<span>
{% unless line_item.properties == empty %}
{% for property in line_item.properties %}
{{ property.first }}: {{ property.last }}
{% endfor %}
{% endunless %}
</span>
