CI4 PDF Customized

This should do the trick.

Code:

composer require tecnickcom/tcpdf

Code:

composer install

PHP Code:

<?php namespace App\Controllers;

use TCPDF;

class Home extends BaseController
{
    public function index()
    {
         $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
    }
} 


How I can run TCPDF without composer?
