Magento 2, How to call front controller from admin page?

Question

Using magento 2, front and admin, I need to access controller in print button on sale order page to print invoice which generate pdf in front view controller. Plz.

Answer 1

If you need to do that, I am sure using redirect to your front end controller should be worked.

public function getPrintUrl()
{
    $baseUrl = $this->_urlInterface->getBaseUrl();
    return $baseUrl.'/order/printpdf/invoice_id/'.$this->getInvoice()->getId();
}
