QR Code dans un PDF

Bonjour, j'ai un autre souci... C'est d'ailleurs le tout premier même, je m'en suis aperçu que maintenant. En effet, quand je lance l'impression d'un PDF avec la librairie "html2pdf_v4.03", l'impression ne se lance pas et j'ai un message d'erreur de ce genre (dernière image) ...
Warning: count(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\1hotelradison-cg.com_old\app\super_admin\html2pdf_v4.03\_class\locale.class.php on line 68

Warning: count(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\1hotelradison-cg.com_old\app\super_admin\html2pdf_v4.03\_class\locale.class.php on line 68
TCPDF ERROR: Some data has already been output, can't send PDF file

Et cela quand je me rends à ligne 68 du fichier "load.class.php" indiqué, je vois ceci :

Re-Bonjour, maintenant il me reste à réussir l'insertion du QR Code ...
Voici le code de mon fichier reservation_web.php qui affiche un tableau de données de la table RESERVATION de ma Base De Données ...

... Le code du fichier "load_reservation.php" qui reçoit l'ID

Ensuit, il ya un fichier "print_reservation.php" qui affiche les infos en PDF ... Ce bout de code pour afficher une information, le NOM DU CLIENT, par exemple :

echo html_entity_decode($reservation['nom']);
