Override a Method of Abstract File of Magento 2 Invoice PDF

Do you want to change your store invoices from boring pieces of paper to new attractive and effective brand building tool in the Magento 2 store? If yes, this post is for you!

Invoices are the official documents that you send with every order that is important for accounting and tax purposes. Default Magento 2 offers invoice template as shown below.

But this is not enough. A store needs to add the signature, logo, etc. elements that help in branding. Also, it improves the appearance of the invoice. It is necessary to optimize the invoice as it is the means of communication that customers promptly open as they are bound to open it to check if they are charged the correct amount. Better invoices help in reinforcing your brand values!

Changing the default Invoice is not a permanent solution. You may lose your changes if your Magento 2 version is upgraded. Also, it is not advisable to make changes in the default configuration. The solution is to override a method of abstract file of Magento 2 invoice PDF.

It enables the custom design of the Invoice, while not disturbing the default settings! Here I am taking an example of how to change the font of invoice pdf that uses the procedure to override a method of abstract file of Magento 2 invoice pdf.

Method to Override a Method of Abstract File of Magento 2 Invoice PDF:

2. Create module.xml in app\code\Vendor\Module\etc and add the following code:
   
   <?xml version="1.0" encoding="UTF-8"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Vendor_Module" setup_version="1.0.0"/> </config>

3. Create di.xml which is located at app\code\Vendor\Module\etc and add the following code:

4. Create Invoice.php in app\code\Vendor\Module\Model\Rewrite\Order\Pdf and add the following code:
   
   <?php namespace Vendor\Module\Model\Rewrite\Order\Pdf; use Magento\Sales\Model\Order\Pdf\Invoice as CoreInvoice; class Invoice extends CoreInvoice { /** * Set font as regular * * @param \Zend_Pdf_Page $object * @param int $size * @return \Zend_Pdf_Resource_Font */ protected function _setFontRegular($object, $size = 7) { $font = \Zend_Pdf_Font::fontWithPath( $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf') ); $object->setFont($font, $size); return $font; } /** * Set font as bold * * @param \Zend_Pdf_Page $object * @param int $size * @return \Zend_Pdf_Resource_Font */ protected function _setFontBold($object, $size = 7) { $font = \Zend_Pdf_Font::fontWithPath( $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf') ); $object->setFont($font, $size); return $font; } /** * Set font as italic * * @param \Zend_Pdf_Page $object * @param int $size * @return \Zend_Pdf_Resource_Font */ protected function _setFontItalic($object, $size = 7) { $font = \Zend_Pdf_Font::fontWithPath( $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf') ); $object->setFont($font, $size); return $font; } }

   <?php   namespace Vendor\Module\Model\Rewrite\Order\Pdf;   use Magento\Sales\Model\Order\Pdf\Invoice as CoreInvoice;   class Invoice extends CoreInvoice {     /**      * Set font as regular      *      * @param \Zend_Pdf_Page $object      * @param int $size      * @return \Zend_Pdf_Resource_Font      */     protected function _setFontRegular($object, $size = 7)     {         $font = \Zend_Pdf_Font::fontWithPath(             $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf')         );         $object->setFont($font, $size);         return $font;     }       /**      * Set font as bold      *      * @param \Zend_Pdf_Page $object      * @param int $size      * @return \Zend_Pdf_Resource_Font      */     protected function _setFontBold($object, $size = 7)     {         $font = \Zend_Pdf_Font::fontWithPath(             $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf')         );         $object->setFont($font, $size);         return $font;     }       /**      * Set font as italic      *      * @param \Zend_Pdf_Page $object      * @param int $size      * @return \Zend_Pdf_Resource_Font      */     protected function _setFontItalic($object, $size = 7)     {         $font = \Zend_Pdf_Font::fontWithPath(             $this->_rootDirectory->getAbsolutePath('lib/internal/dejavu-sans/DejaVuSansCondensed.ttf')         );         $object->setFont($font, $size);         return $font;     }   }

    

When you implement the above method, you can set the custom font in the Invoice pdf. Similarly, you can design custom Invoice pdf too!

You can send Invoices that serve as the marketing tool as shown here using the above method:

No more sloppy and unprofessional Emails that you have to change with every Magento 2 upgrade!

Hopefully, your customers will be impacted with the invoice marketing technique
