app('App\Http\Controllers\PrintReportController')->getPrintReport();

use App\Http\Controllers\OtherController;

class TestController extends Controller
{
    public function index()
    {
        //Calling a method that is from the OtherController
        $result = (new OtherController)->method();
    }
}

2) Second way

app('App\Http\Controllers\OtherController')->method();

Both way you can get another controller function.

$myRequest = new Request();
$myRequest->request->add(['foo' => 'bar']);
var_dump($myRequest->foo);
