Victoria commented on Modifying the Order Printer App Template by Shopify

Hey Robert! 

Victoria here from Shopify. To remove the code for the price will depend on exactly what you want to keep on the invoice. I created an alternate for you that does not have the shipping price, the tax, or the price of the item. The code I used was: 

<p style="float: right; text-align: right; margin: 0;">
  {{ "now" | date: "%m/%d/%y" }}<br />
  Invoice for {{ order_name }}</p><div style="float: left; margin: 0 0 1.5em 0;" ><strong style="font-size: 2em;">{{ shop_name }}</strong><br /><br />
  {{ shop.address }}<br/>
  {{ shop.city }} {{ shop.province_code }} {{ shop.zip | upcase }}<br/>
  {{ shop.country }}</div><hr /><h3 style="margin: 0 0 1em 0;">Item Details</h3><table class="table-tabular" style="margin: 0 0 1.5em 0;"><thead><tr><th>Quantity</th><th>Item</th>
      {% if show_line_item_taxes %}<th></th>
      {% endif %}<th></th></tr></thead><tbody>
    {% for line_item in line_items %}<tr><td>{{ line_item.quantity }} x</td><td><b>{{ line_item.title }}</b></td>
        {% if line_item.tax_lines %}<td>
            {% for tax_line in line_item.tax_lines %}<br/>
            {% endfor %}</td>
        {% endif %}<td></td></tr>
    {% endfor %}</tbody></table>

{% if transactions.size > 1 %}<h3 style="margin: 0 0 1em 0;">Transaction Details</h3><table class="table-tabular" style="margin: 0 0 1.5em 0;"><thead><tr><th>Type</th><th>Amount</th><th>Kind</th><th>Status</th></tr></thead><tbody>
      {% for transaction in transactions %}<tr><td>{{ transaction.gateway | payment_method }}</td><td>{{ transaction.amount | money }}</td><td>{{ transaction.kind }}</td><td>{{ transaction.status }}</td></tr>
      {% endfor %}</tbody></table>
{% endif %}</tr>
  {% if shipping_address %}<tr></tr>
  {% endif %}

{% if note %}
  <h3 style="margin: 0 0 1em 0;">Note</h3><p>{{ note }}</p>
{% endif %}

{% if shipping_address %}
  <h3 style="margin: 0 0 1em 0;">Shipping Details</h3><div style="margin: 0 0 1em 0; padding: 1em; border: 1px solid black;"><strong>{{ shipping_address.name }}</strong><br/>
    {% if shipping_address.company %}
      {{ shipping_address.company }}<br/>
    {% endif %}
    {{ shipping_address.street }}<br/>
    {{ shipping_address.city }}
    {{ shipping_address.province_code }}
    {{ shipping_address.zip | upcase }}<br/>
    {{ shipping_address.country }}</div>
{% endif %}

The result of this template will appear like this here: 

Hope that helps! :)
