I want to add text to the pdf invoice in the marked arena (see photo).

I'm using Magento version 1.9.2.1

How can I do this?

You can add specific text after total price follow the code

First override that block add this code in your config file between <global/>:

<models>
 <sales>
 <rewrite>
 <order_pdf_invoice>Namespace_Module_Model_Order_Pdf_Invoice</order_pdf_invoice>
 </rewrite>
 </sales>
 </models>

Create file in app/code/local/Namespace/Module/Model/Order/Pdf/Invoice.php and add the below function at the end of the file:

<?php 
class Mage_Sales_Model_Order_Pdf_Invoice extends Mage_Sales_Model_Order_Pdf_Abstract 
{
 public function insertText($page)
 
 $page->drawLine(25, $this->y, 570, $this->y); 
 $this->y -= 25;
 $page->drawText(Mage::helper('sales')->__('Add here Your custom text'), 35, $this->y, 'UTF-8');
 

Now, you need to call this insertText() function in the getPdf() function and add this getPdf() function after insertText() function like here:

public function getPdf($invoices = array())

 $this->_beforeGetPdf();
 $this->_initRenderer('invoice');

 $pdf = new Zend_Pdf();
 $this->_setPdf($pdf);
 $style = new Zend_Pdf_Style();
 $this->_setFontBold($style, 10);

 foreach ($invoices as $invoice) 
 if ($invoice->getStoreId()) 
 Mage::app()->getLocale()->emulate($invoice->getStoreId());
 Mage::app()->setCurrentStore($invoice->getStoreId());
 
 $page = $this->newPage();
 $order = $invoice->getOrder();
 /* Add image */
 $this->insertLogo($page, $invoice->getStore());
 /* Add address */
 $this->insertAddress($page, $invoice->getStore());
 /* Add head */
 $this->insertOrder(
 $page,
 $order,
 Mage::getStoreConfigFlag(self::XML_PATH_SALES_PDF_INVOICE_PUT_ORDER_ID, $order->getStoreId())
 );
 /* Add document text and number */
 $this->insertDocumentNumber(
 $page,
 Mage::helper('sales')->__('Invoice # ') . $invoice->getIncrementId()
 );
 /* Add table */
 $this->_drawHeader($page);
 /* Add body */
 foreach ($invoice->getAllItems() as $item)
 if ($item->getOrderItem()->getParentItem()) 
 continue;
 
 /* Draw item */
 $this->_drawItem($item, $page, $order);
 $page = end($pdf->pages);
 
 /* Add totals */
 $this->insertTotals($page, $invoice);
 if ($invoice->getStoreId()) 
 Mage::app()->getLocale()->revert();
 
 
 $this->insertText($page); // your custom text is added here
 $this->_afterGetPdf();
 return $pdf;

$this->insertText($page); that call your custom text function so you need to add before $this->_afterGetPdf(); this function.

I was able to add text to the invoice pdf by creating a local copy of the core directory(files/folders) app/code/core/Mage/Sales/Model/Order/Pdf/Invoice.php as app/code/local/Mage/Sales/Model/Order/Pdf/Invoice.php and added the insertText() function as stated above.
