{{ :dummy.png?75x75|Nom de la section}}


Un fichier PPD est un descripteur qui contient des informations sur les fonctionnalités de l'imprimante, telles que les résolutions d'impression disponibles, les options de finition et les polices de caractères disponibles. Les systèmes d'exploitation, y compris Linux, utilisent les informations contenues dans le PPD pour configurer l'imprimante et fournir des options d'impression avancées.

Pour utiliser un PPD sous Linux, vous devez tout d'abord installer le pilote d'imprimante correspondant à votre imprimante.

Pour l'imprimante **Ricoh SP C252DN** sélectionner le protocole JetDirect.
