Printing 为来宾Magento启用打印订单功能

我需要为客人结账启用打印订单功能

对于已登录的用户，打印功能工作正常

但对于来宾用户，打印按钮在成功页面上不可见 要显示打印按钮，我已删除签入文件success.phtml

但我不明白如何使打印功能，客人没有登录可用。

请提前向我表示感谢

您应该尝试此扩展：它工作得非常好，是一种节省的方式，可以在客人结账后提供订单确认的打印链接。

在Magento 2中： 您必须覆盖模块Sales，然后覆盖以下2个控制器，如下所示：

app/code/YourVendorName/Sales/etc/di.xml

 <preference for="Magento\Sales\Controller\Order\PrintAction" type="YourVendorNAme\Sales\Controller\Order\PrintAction"/>
<preference for="Magento\Sales\Controller\AbstractController\OrderLoader" type="YourVendorNAme\Sales\Controller\AbstractController\OrderLoader"/>

    public function __construct(

        \Magento\Sales\Controller\AbstractController\OrderViewAuthorizationInterface $orderAuthorization,

    }

    /**

     */
    public function load(RequestInterface $request)
    {
        $orderId = (int)$request->getParam('order_id');
        if (!$orderId) {
            /** @var Forward $resultForward */

            $this->registry->register('current_order', $order);
            return true;
        }

        /** @var Redirect $resultRedirect */
        $resultRedirect = $this->redirectFactory->create();
        return $resultRedirect->setUrl($this->url->getUrl('*/*/history'));
    }
}
