在Magento中编辑PDF是受限制的，但是如果你需要编辑的只是一个地址，你可以使用事件。

首先在config.xml中设置你的观测者：

<adminhtml>
    	<events>
    	    <customer_address_format>
    		<observers>
                    <alwayly_sales_customer_address_format_observer>
                        <type>model</type>
                        <class>alwayly_sales/observer</class>
                        <method>addAdditionalDataToAddress</method>
                    </alwayly_sales_customer_address_format_observer>
                </observers>
    	    </customer_address_format>
    	</events>
</adminhtml>

在设置完观测者之后，你需要写代码来编辑地址模版：

/**
 * Observer printing invoices in PDF
 *
 * @category    Alwayly
 * @package     Alwayly_Sales
 */
class Alwayly_Sales_Model_Observer
{
    public function addAdditionalDataToAddress(Varien_Event_Observer $address)
    {
    	$data = $address->getEvent();
    	if($data->type['code']=="pdf")
    	{
    		$customerData = $data["address"]->getOrder()->getData();
    		$customerId = $customerData['customer_id'];
    		//we are using customer object because it give us latest user data, if you want data from user on order creation use $customerData
			$customer = Mage::getModel('customer/customer')->load($customerId);
			$customerVariable = $customer->get?????;
 
			//prevent of multiple insertion
    		if(strpos($data->type['default_format'],"Customer Variable")===false)
    		{
    		 	$stringToInsert = "{{var company}}|{{/depend}}|Customer Variable: ".$customerVariable."|";
    		 	$data->type['default_format'] = str_replace("{{var company}}|{{/depend}}",$stringToInsert, $data->type['default_format']);
    		};
    	};
    }
}

如果你想要获取最后一个用户的数据，你要使用Mage::getModel(‘customer/customer’) 对象。注意，用你自己的数据替换?????。我们获取地址模版并做修改。
