Printing custom file with dompdf

hi, i’d like to generate a PDF file from a Custom File, but the pdf is not being generated.
this is my code for the custom file_Content:

<a href="#" id="print-btn" class="btn btn-primary">Print PDF</a>

<div id="printable-area">
    <p style="color:red;">Test</p>
</div>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function() {
    $("#print-btn").click(function() {
      var printableContent = $("#printable-area").html();
      $.ajax({
        type: "POST",
        url: "print.php",
        data: { printableContent: printableContent },
        success: function(data) {
          console.log("PDF created successfully!");
        },
        error: function(xhr, status, error) {
          console.log("An error occurred while creating PDF.");
        }
      });
    });
  });
</script>

an this is the code for print.php that’s situated in the base project forlder (localost/test/print.php):

<?php
require_once 'vendor/autoload.php';
use Dompdf\Dompdf;

if (isset($_POST['printableContent'])) {
    $printableContent = $_POST['printableContent'];
    ob_get_clean(); 
    $dompdf = new Dompdf();
    $dompdf->loadHtml($printableContent);
    $dompdf->setPaper('A4', 'portrait');
    $dompdf->render();
    $dompdf->stream();
}
?>

the console log that’ive setted give me “PDF created successfully!”
and if i use:
console.log(data);
it gives me some code similare to a pdf structure.i’ve tried to add:

          const pdfBlob = new Blob([data], { type: 'application/pdf' });
          const pdfUrl = URL.createObjectURL(pdfBlob);
          window.open(pdfUrl);

for success, ad it open a blank pdf.
any ide to solve this?
Thanks
