You need to override this file:

vendor/magento/module-sales/Controller/Adminhtml/Invoice/AbstractInvoice/PrintAction.php

• In VendorName/ModuleName/etc/di.xml file, add the following code to Register the overridden controller:

• In VendorName/ModuleName/Controller/Adminhtml/Invoice/AbstractInvoice/PrintAction.php file, extend the Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\PrintAction class and override the execute() method.

<?php

namespace VendorName\ModuleName\Controller\Adminhtml\Invoice\AbstractInvoice;

use Magento\Framework\App\ResponseInterface;

use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Framework\Exception\NotFoundException;
use Magento\Framework\Exception\LocalizedException;

class PrintAction extends \Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\PrintAction
{
    public function execute()
    {
        $invoiceId = $this->getRequest()->getParam('invoice_id');
        if ($invoiceId) {
            $invoice = $this->_objectManager->create(
                \Magento\Sales\Api\InvoiceRepositoryInterface::class
            )->get($invoiceId);
            if ($invoice) {
                $pdf = $this->_objectManager->create(\Magento\Sales\Model\Order\Pdf\Invoice::class)->getPdf([$invoice]);
                $date = $this->_objectManager->get(

                $fileContent = ['type' => 'string', 'value' => $pdf->render(), 'rm' => true];

                $orderIncrementalId = $invoice->getOrder()->getIncrementId();
                return $this->_fileFactory->create(
