use Magento\Sales\Model\Order\Pdf\Config;

protected $_localeResolver;

    public function __construct(
        \Magento\Payment\Helper\Data $paymentData,
        \Magento\Framework\Stdlib\StringUtils $string,
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
        \Magento\Framework\Filesystem $filesystem,
        Config $pdfConfig,
        \Magento\Sales\Model\Order\Pdf\Total\Factory $pdfTotalFactory,
        \Magento\Sales\Model\Order\Pdf\ItemsFactory $pdfItemsFactory,
        \Magento\Framework\Stdlib\DateTime\TimezoneInterface $localeDate,
        \Magento\Framework\Translate\Inline\StateInterface $inlineTranslation,
        \Magento\Sales\Model\Order\Address\Renderer $addressRenderer,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Store\Model\App\Emulation $appEmulation,
        \Magento\Framework\Locale\ResolverInterface $localeResolver,
        array $data = []
    ) 
{
        $this->_localeResolver = $localeResolver;
        parent::__construct(
            $paymentData,
            $string,
            $scopeConfig,
            $filesystem,
            $pdfConfig,
            $pdfTotalFactory,
            $pdfItemsFactory,
            $localeDate,
            $inlineTranslation,
            $addressRenderer,
            $storeManager,
            $appEmulation,
