I tried to send an invoice email from frontend with pdf attached, by extending InvoiceSender like this:

namespace NamespageModuleModelPluginOrder;



use MagentoSalesModelOrderInvoice;

use MagentoFrameworkDataObject;

use MagentoSalesModelOrder;



class InvoiceSender extends MagentoSalesModelOrderEmailSenderInvoiceSender

{

  public function send(Invoice $invoice, $forceSyncMode = false)

  {

      $invoice->setSendEmail(true);



      if (!$this->globalConfig->getValue('sales_email/general/async_sending') || $forceSyncMode) {

          $order = $invoice->getOrder();



          $objectManager = MagentoFrameworkAppObjectManager::getInstance();



          //start attact pdf invoce

          $pdf = $objectManager->create('MagentoSalesModelOrderPdfInvoice')->getPdf([$invoice]);

          $date = $objectManager->create('MagentoFrameworkStdlibDateTimeDateTime')->date('Y-m-d_H-i-s');

          $pdf->render();

          $message = $objectManager->get('MagentoFrameworkMailMessage');

          $message->createAttachment(

              $pdf->render(),

              Zend_Mime::TYPE_OCTETSTREAM,

              Zend_Mime::DISPOSITION_ATTACHMENT,

              Zend_Mime::ENCODING_BASE64,

              'invoice-'.$invoice->getId().'.pdf'

          );

          //end attach pdf invoce



          $transport = [

              'order' => $order,

              'invoice' => $invoice,

              'comment' => $invoice->getCustomerNoteNotify() ? $invoice->getCustomerNote() : '',

              'billing' => $order->getBillingAddress(),

              'payment_html' => $this->getPaymentHtml($order),

              'store' => $order->getStore(),

              'formattedShippingAddress' => $this->getFormattedShippingAddress($order),

              'formattedBillingAddress' => $this->getFormattedBillingAddress($order)

          ];

          $transportObject = new DataObject($transport);



          /**

           * Event argument `transport` is @deprecated. Use `transportObject` instead.

           */

          $this->eventManager->dispatch(

              'email_invoice_set_template_vars_before',

              ['sender' => $this, 'transport' => $transportObject->getData(), 'transportObject' => $transportObject]

          );



          $this->templateContainer->setTemplateVars($transportObject->getData());



          if ($this->checkAndSend($order)) {

              $invoice->setEmailSent(true);

              $this->invoiceResource->saveAttribute($invoice, ['send_email', 'email_sent']);

              return true;

          }

          return true;

      } else {

          $invoice->setEmailSent(null);

          $this->invoiceResource->saveAttribute($invoice, 'email_sent');

      }



      $this->invoiceResource->saveAttribute($invoice, 'send_email');



      return false;

  }



  protected function checkAndSend(Order $order)

  {

      $this->identityContainer->setStore($order->getStore());

      $this->prepareTemplate($order);



      /** @var SenderBuilder $sender */

      $sender = $this->getSender();



      try {

          $sender->send();

          $sender->sendCopyTo();

      } catch (Exception $e) {

          $this->logger->error($e->getMessage());

      }



      return true;

  }

}

the problem seems occure when getPdf(...) function being called, and shows an error like this:

1 exception(s): Exception #0
(MagentoFrameworkExceptionValidatorException): Invalid template
file: 'Magento_OfflinePayments::info/pdf/checkmo.phtml' in module:
'Magento_OfflinePayments' block's name: 'infocheckmo_0'

Exception #0 (MagentoFrameworkExceptionValidatorException): Invalid
template file: 'Magento_OfflinePayments::info/pdf/checkmo.phtml' in
module: 'Magento_OfflinePayments' block's name: 'infocheckmo_0'

Magento_OfflinePayments::info/pdf/checkmo.phtml file cannot be found.

This is due to a Core bug in 2.1, 2.2, maybe 2.3. Create a plugin to fix it :

• 
  

  In appcodeNamespaceModuleetcdi.xml

  
  
  

  <?xml version="1.0" ?>
  
  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
  
      <type name="MagentoOfflinePaymentsBlockInfoCheckmo">
  
          <plugin sortOrder="1" name="namespaceModuleCheckmo" type="NamespaceModulePluginBlockInfoCheckmoPlugin"/>
  
      </type>
  
  </config>
  
  

  
  


• 
  

  In appcodeNamespaceModulePluginBlockInfoCheckmoPlugin.php

  
  
  

  <?php
  
  
  
  namespace NamespaceModulePluginBlockInfo;
  
  
  
  /**
  
   * Class CheckmoPlugin
  
   * @package NamespaceModulePluginBlockInfo
  
   */
  
  class CheckmoPlugin
  
  {
  
      /**
  
       * @param MagentoOfflinePaymentsBlockInfoCheckmo $subject
  
       * @param callable $proceed
  
       */
  
      public function aroundToPdf(MagentoOfflinePaymentsBlockInfoCheckmo $subject, callable $proceed)
  
      {
  
          return __('Check / Money order');
  
      }
  
  }

  Finally, in command line :

  
  
  

  php bin/magento setup:di:compile
  
  php bin/magento setup:upgrade
