- Responsible Vendor File For Invoice Pdf Product Data :
vendor/magento/module-sales/Model/Order/Pdf/Items/Invoice/DefaultInvoice.php
- Override in your custom module like this :
Vendorname\Modulename\Model\Magento\Sales\Order\Pdf\Items\Invoice\DefaultInvoice.php
- Define in DI file [di.xml] :
<preference for="Magento\Sales\Model\Order\Pdf\Items\Invoice\DefaultInvoice" type="Vendorname\Modulename\Model\Magento\Sales\Order\Pdf\Items\Invoice\DefaultInvoice"/>
Now you Need to add some code in draw() function and make custom getProductImage() function in your Custom DefaultInvoice.php file
<?php
namespace Vendorname\Modulename\Model\Magento\Sales\Order\Pdf\Items\Invoice;
use Vendorname\Modulename\Model\Magento\Sales\Order\Pdf\Invoice;
use Magento\Framework\App\Filesystem\DirectoryList;

public function draw()

'text' => '',
'feed' => 35,
'is_image' => true,
'image' => $productImage,
);
// draw SKU
$lines[0][] = [
'text' => $this->string->split($this->getSku($item), 17),
'feed' => 370,
'align' => 'right',

// draw QTY
$lines[0][] = ['text' => $item->getQty() * 1, 'feed' => 475, 'align' => 'right'];
// draw item Prices

}
}
}
$lineBlock = ['lines' => $lines, 'height' => 20];
$page = $pdf->drawLineBlocks($page, [$lineBlock], ['table_header' => true],1);
