laravel call controller method from another controller

// Include the other controller in this controller
use App\Http\Controllers\TasksController;

// Instantiate other controller class in this controller's method
$tasks_controller = new TasksController;
// Use other controller's method in this controller's method
$tasks_controller->postNotification($comment_content, $author);

Just try this in your view :

{{ ControllerName::Functionname($params); }}
OR

<?php echo ControllerName::Functionname($params);?>

$printReport = new PrintReportController;

$prinReport->getPrintReport();
