That's not a CodeIgniter problem, as it loading the library. That's a TCPDF problem and I'm guessing it's do to the fact you aren't sending any application/pdf headers from your server.

By coincidence, I've just spent the last 2 hrs fighting hard with the same problem and I don't believe it has anything to do with tcpdf because I have tried it with a regular pdf from elsewhere. Using force_download in ci3 has worked perfectly for the past 2/3 years. I've tried every combination of the following code and nothing works. If I enable the line "
Code:
setContentType('application/pdf')
" then Chrome reports "unable to download" but firefox reports "might not be displayed correctly" and using "open with different viewer" dialog says the document has 0 bytes
Code:
return $this->response//->setHeader('Pragma','public')
        //->setHeader('Expires','0')
        //->setHeader('Cache-Control','must-revalidate, post-check=0, pre-check=0')
        //->setHeader('Content-Disposition','inline; filename="'.$filename.'"')
        //->setContentType('application/pdf')
        //->setHeader('Content-Length',filesize($fullname))
        ->download($fullname);//'',true);//,$data);
I can create pdf files with tcpdf in ci4 and view them standalone with no problem but am unable to download via ci4.

*** SOLVED CI4 + TCPDF***
I had same problem. TCPDF was showing weird characters like %PDF-1.7 %���� 5 0 obj << /Type /Page /Parent 1 0 R

I just added exit(); at the end of the code. It works for me.

Example:
$pdf->Output('filename.pdf', 'I');
exit();

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_ORIENTATIONPDF_UNITPDF_PAGE_FORMATtrue'UTF-8'false);
    }

How I can run TCPDF without composer?

I installed it as an unzip into thirdparty/TCPDFMaster and created a file MyPdf.php in libraries with the following
PHP Code:
<?php namespace App\Libraries;
use 
App\ThirdParty\TCPDFmaster\Tcpdf;
class 
MyPdf extends TCPDF {
    function 
__construct()
    {
        
parent::__construct();
    }


and then in my controller
PHP Code:
$pdf = new MyPdf();
        
$pdf->AddPage();
        
$pdf->writeHTMLCell(....
        
etc etc
        $filename
=whatever;
        
$file fullpathto $filename;
        
// save as file
        
$pdf->Output($file'F');
        
// send to browser
        
$this->response->setHeader('Content-Type''application/pdf');
        
$this->response->setHeader('Content-Disposition: inline;''filename="' $filename '"');
        
$this->response->setHeader('Content-Transfer-Encoding''binary');
        
$this->response->setHeader('Content-Length: 'filesize($file),'');
        
$this->response->setHeader('Accept-Ranges:''bytes');
        
readfile($file);

Hi, thanks for the help with the code @badger. You don't need this part however, if it's just executing the parent code.
PHP Code:
function __construct()
{
    
parent::__construct();
