How to add additional text to invoice

Question

I'm currently working on magento 1.9 and wanted to add some additional text to invoice when we print in from admin panel like this :

As you can see above red numbers are the additional text for the invoice.

How do I do that in magento 1.9 ? Please help me on this and I really appreciate if you show me step by step to achieve this.

Answer 1

you can do this by creating the Invoice.php in the following path : local/[Vendor]/Module/Model/Order/Pdf/Invoice.php.

class YouClass extends Mage_Sales_Model_Order_Pdf_Invoice
{

    /**
     * @param Zend_Pdf_Page $page
     * @param  '??' $order
     * @return void
     */
    protected function _drawBottomText(Zend_Pdf_Page $page, $order)
    {
        $this->_setFontRegular($page, 10);

        /* Getting the DPP */
        $Dpp = $order->getGrandTotal() / 1.1;
        $Ppn = $Dpp * 0.1; // dpp * 10%

        /* Convert the number to currency */
        $DppCurrency  =number_format($Dpp, 2, '.', ',');
        $PpnCurrency= number_format($Ppn, 2, '.', ',');
        $Currency = Mage::app()->getLocale()->currency(Mage::app()->getStore()->getCurrentCurrencyCode())->getSymbol();

        $page->drawText('DPP : ' . $Currency .' '. $DppCurrency,35,$this->y,'UTF-8');
        $page->drawText('PPN : ' . $Currency .' ' . $PpnCurrency,35,$this->y-20,'UTF-8');

        $page->drawText('Harga BKP sudah termasuk pajak',35,$this->y-40,'UTF-8');
        $page->drawText('PT KAYU RAYA INDONESIA',35,$this->y-55,'UTF-8');
        $page->drawText('Kawasan Industri dan Pergudangan Taman tekno BSD',35,$this->y-65,'UTF-8');
        $page->drawText('City Sektor XI Blok C No 2, Kota Tangerang Selatan',35,$this->y-75,'UTF-8');
        $page->drawText('NPWP: 76.406.266.7-411.000',35,$this->y-85,'UTF-8');
        $page->drawText('PKP: 76.406.266.7-411.000',35,$this->y-95,'UTF-8');

    }

    /**
     * Return PDF document
     *
     * @param  array $invoices
     * @return Zend_Pdf
     */
    public function getPdf($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();
            }
            /* Add bottom text for details tax and company*/
            $this->_drawBottomText($page,$order);
        }
        $this->_afterGetPdf();
        return $pdf;
    }
}

and register the class in your config.xml file in etc folder :

    <models>
        <sales>
            <rewrite>                    
                <order_pdf_invoice>YourClass</order_pdf_invoice>
            </rewrite>
        </sales>
    </models>

It is hard for me to adjust the text to match exactly like the screen shot, but this one displaying additional text and does the work.
