iNetBSD 8.1 mpression impossible (cups+hplip)

[Philippe BERNARD <pb29%free.fr@localhost>]

Bonjour,

Je reviens vers vous pour un problème d'impression... et un bon coup de main !

Je dispose d'une imprimante HP Deskjet_3055A connectée sur mon réseau perso en wifi, opérationnelle sous Linux et OpenBSD. Ma machine est sous NetBSD 8.1, noyau GENERIC amd64.
Le document est bien envoyé à l'imprimante, mais en sortie seuls sont imprimés les caractères suivants:
