Vendor/module/etc/di.xml,
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

</config>
Now you can create Vendor\module\Model\Order\Pdf\InvoicePdf.php file & add the below code,
<?php
namespace Vendor\module\Model\Order\Pdf;
use \Magento\Sales\Model\Order\Pdf\Invoice;
class InvoicePdf extends Invoice
{
public function getPdf($invoices = []) {
$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()) {
$this->_localeResolver->emulate($invoice->getStoreId());
$this->_storeManager->setCurrentStore($invoice->getStoreId());
}
$page = $this->newPage();
$order = $invoice->getOrder();
$this->insertLogo($page, $invoice->getStore());
$this->insertAddress($page, $invoice->getStore());
$this->insertOrder(
$page,
$order,
$this->_scopeConfig->isSetFlag(
self::XML_PATH_SALES_PDF_INVOICE_PUT_ORDER_ID,
\Magento\Store\Model\ScopeInterface::SCOPE_STORE,
$order->getStoreId()
)
);
$this->insertDocumentNumber($page, __('Invoice # ') . $invoice->getIncrementId());
$this->_drawHeader($page);
foreach ($invoice->getAllItems() as $item) {
if ($item->getOrderItem()->getParentItem()) {
continue;
}
$this->_drawItem($item, $page, $order);
$page = end($pdf->pages);
}
$this->insertTotals($page, $invoice);
if ($invoice->getStoreId()) {
$this->_localeResolver->revert();
}
$this->drawNotice($page);
}
$this->_afterGetPdf();
return $pdf;
}
protected function drawNotice(\Zend_Pdf_Page $page) {
$iFontSize = 10;
$iColumnWidth = 520;
$iWidthBorder = 260;
$iXCoordinateText = 30;
$sEncoding = 'UTF-8';
$this->draw -= 10;
try {
$oFont = $this->_setFontRegular($page, $iFontSize);
$iXCoordinateText = $this->getAlignCenter($sNotice, $iXCoordinateText, $iColumnWidth, $oFont, $iFontSize);
$page->setLineColor(new \Zend_Pdf_Color_Rgb(1, 0, 0));
$iXCoordinateBorder = $iXCoordinateText - 10;
$page->drawLine($iXCoordinateBorder, $this->draw, $iXCoordinateBorder + $iWidthBorder, $this->draw);
$this->draw -= 15;
$page->drawText($sNotice, $iXCoordinateText, $this->draw, $sEncoding);
$this->draw -= 10;
$page->drawLine($iXCoordinateBorder, $this->draw, $iXCoordinateBorder + $iWidthBorder, $this->draw);
$this->draw -= 10;
} catch (\Exception $exception) {
}
}
protected function _drawHeader(\Zend_Pdf_Page $page)
{
$this->_setFontRegular($page, 10);
$page->setFillColor(new \Zend_Pdf_Color_Rgb(0.93, 0.92, 0.92));
$page->setLineColor(new \Zend_Pdf_Color_GrayScale(0.5));
$page->setLineWidth(0.5);
$page->drawRectangle(25, $this->y, 570, $this->y - 15);
$this->y -= 10;
$page->setFillColor(new \Zend_Pdf_Color_Rgb(0, 0, 0));
//columns headers
$lines[0][] = ['text' => __('Products'), 'feed' => 35];
$lines[0][] = ['text' => __('SKU'), 'feed' => 290, 'align' => 'right'];
// custom column
$lines[0][] = ['text' => __('Qty'), 'feed' => 435, 'align' => 'right'];

$page->setFillColor(new \Zend_Pdf_Color_GrayScale(0));
$this->y -= 20;
}
}
