Laravel - FPDF error: Undefined font

Navigation
1

What I'm doing

I'm rewriting a small bar code generation system using Laravel.

What went wrong

I'm instantiating classes normally, but when I use the $pdf->SetFont('Arial','B',$fontSize); method I get the message FPDF error: Undefined font: helvetica B . As you can see in the image below, the "font" folder is already included inside the library folder. I went into the library and looked for the SetFont method, and just changed the folder path, since the lib e and font file is inside my directory.

My Code

I will leave only small parts of the code 

<?php namespace App\Http\Controllers;

//Declaração de uso de elementos para layout, bibliotecas e depois model com bd
use View, Input, Validator, FPDF, eFPDF, BarcodeClass, BarcodeEAN, DB, App\Models\Barcode;

class HomeController extends Controller {

public function index() {
    return view('frontend.home');
}

public function gerarPdf() {

    //parte inicial do código

    //Cria um novo PDF
    $pdf = new eFPDF('P', 'pt');

    //Modifica informações de visualização do PDF
    $pdf->SetFont('Arial','B',$fontSize);

Within the class FPDF.php it has the method below that is called to import the fonts. 

function _getfontpath()
{
    if(!defined('FPDF_FONTPATH') && is_dir(dirname(__FILE__).'font/'))
        define('FPDF_FONTPATH',dirname(__FILE__).'/font/');
    return defined('FPDF_FONTPATH') ? FPDF_FONTPATH : '';
}

First of all, the getPath method was being called but define was not getting the full path of the folder. The dirname of it was not working, so I changed it to app_path().'/Libraries/FPDF/font/' , and at the end of the generatePdf method soon after $pdf->Output I put exit; otherwise the browser would show the characters below:

% PDF-1.3 3 0 obj < > endobj 40 obj < > stream x e N 0 } R < ?

What would this eFPDF be?

An example would be like this 

public function gerarPdf() {       
      $fpdf = new Fpdf();
             $fpdf->AddPage();
             $fpdf->SetFont('Arial','B',16);
             $fpdf->Output();
             exit;
}
