I will try to give you a step by step answer (tested for laravel 5.1):

Before using it, be sure that you installed the TCPDF service provider correctly:

Installing TCPDF service provider

In composer.json, add this package:

"require": {
    "elibyy/laravel-tcpdf": "0.*"
}

Run composer update

in config/app.php add this service provider

'providers' => [
    //..
    Elibyy\TCPDF\ServiceProvider::class,
]

Run php artisan vendor:publish , that will generate config/laravel-tcpdf.php in your files

Generate the pdf in your controller

public function createPDF()
{
    [...]
    //get default settings from config/laravel-tcpdf.php
    $pdf_settings = \Config::get('laravel-tcpdf');

   $pdf = new \Elibyy\TCPDF\TCPdf($pdf_settings['page_orientation'], $pdf_settings['page_units'], $pdf_settings['page_format'], true, 'UTF-8', false);

   $pdf->SetPrintHeader(false);
        $pdf->SetPrintFooter(false);
        $pdf->AddPage();
        $pdf->writeHTML(view('forms.'.$company.'.'.$branch.'.'.$sub_branch.'.'.$form_type.'.'.$form_name, $data)->render());
        $filename = storage_path().'/forms_pdf/10006/26/4718326/'.$form_name.'.pdf';
        $pdf->output($filename, 'I');
        return redirect('forms');

}
