Impossible d'acceder a l'admin de cups

Salut a tous, voilà, j’utilise cups dans des ecoles, j’ai toujours un mal de chiens a le configurer…j’ai donc recuperer un cupsd.conf avec lequel ca fonctionne, je le copie sur un autre serveur…et là!!! ca ne fonctionne pas!!! mes serveurs ont la meme IP!! mes machines aussi!!..je ne comprends plus rien!

J’accede a l’interface par 192.168.1.49:631/ mais lorsque je clique sur “add prnter” j’obtiens “impossible d’afficher la page”

voici mon cupsd.conf
