title: LARAVEL 5.7 FPDF - Config file to change orientation of PDF is not working
body: <p>I'm using Laravel 5.7 on my application and I installed codedge/laravel-fpdf to create PDF files. The installation was successful and I was able to generate PDF file with their sample on the documentation:</p>
  
  <pre><code>Fpdf::AddPage();
  Fpdf::SetFont('Courier', 'B', 18);
  Fpdf::Cell(50, 25, 'Hello World!');
  Fpdf::Output();
  exit();
  </code></pre>
  
  <p>However, I want to change the paper size and page orientation. So I run:</p>
  
  <pre><code>php artisan vendor:publish --provider="Codedge\Fpdf\FpdfServiceProvider" --tag=config
  </code></pre>
  
  <p>and it generates config file at config/fpdf.php</p>
  
  <p>When I try to change the orientation and size it doesn't work.</p>
  
  <pre><code>'orientation'   =&gt; 'L',
  'unit'          =&gt; 'mm',
  'size'          =&gt; 'Letter',
  </code></pre>
  
  <p>What could be the possible reason to this?</p>
