Body
Lets see what is going on. As we can see from the url (www.example.com/index.php/admin/sales_invoice/view/invoice_id/[some_id]/) <code>Mage_Adminhtml_Sales_Order_InvoiceController</code>'s <code>view</code> action is executed and this is corresponds to <code><adminhtml_sales_order_invoice_view></code> layout (app/design/adminhtml/default/default/layout/sales.xml) node. There we can see this: <pre><code><adminhtml_sales_order_invoice_view> <reference name="content"> <block type="adminhtml/sales_order_invoice_view" name="sales_invoice_view"> ... </code></pre> We can see there that top block is <code>Mage_Adminhtml_Block_Sales_Order_Invoice_View</code>. There we can see (at the end of <code>__construct()</code> method): <pre><code>if ($this->getInvoice()->getId()) { $this->_addButton('print', array( 'label' => Mage::helper('sales')->__('Print'), 'class' => 'save', 'onclick' => 'setLocation(\''.$this->getPrintUrl().'\')' ) ); } </code></pre> and <pre><code>public function getPrintUrl() { return $this->getUrl('*/*/print', array( 'invoice_id' => $this->getInvoice()->getId() )); } </code></pre> Here we can see that our invoice PDF is created from a <code>print</code> action of current module/controller so lets see <code>Mage_Adminhtml_Sales_Order_InvoiceController</code> again and search for a required action method: <pre><code>/** * Create pdf for current invoice */ public function printAction() { $this->_initInvoice(); parent::printAction(); } </code></pre> and in parent <code>Mage_Adminhtml_Controller_Sales_Invoice</code>: <pre><code>public function printAction() { if ($invoiceId = $this->getRequest()->getParam('invoice_id')) { if ($invoice = Mage::getModel('sales/order_invoice')->load($invoiceId)) { $pdf = Mage::getModel('sales/order_pdf_invoice')->getPdf(array($invoice)); $this->_prepareDownloadResponse('invoice'.Mage::getSingleton('core/date')->date('Y-m-d_H-i-s'). '.pdf', $pdf->render(), 'application/pdf'); } } else { $this->_forward('noRoute'); } } </code></pre> As we can see the PDF is created by <code>sales/order_pdf_invoice</code> model (or <code>Mage_Sales_Model_Order_Pdf_Invoice</code> class). Inside of a <code>getPdf()</code> method is a call <code>$this->insertTotals($page, $invoice);</code> which is defined in <code>Mage_Sales_Model_Order_Pdf_Abstract</code> class. My suggestion is to overwrite <code>Mage_Sales_Model_Order_Pdf_Invoice</code> class and define there a custom <code>insertTotals($page, $invoice)</code> method to achieve what you need. I decided to give a full picture of the situation to let you decide how to solve this task.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
