D\u00e9cochez la case R\u00e9\u00e9chantillonner et d\u00e9finissez la r\u00e9solution sur 300 ppp. Les valeurs Largeur\/Hauteur affichent alors la taille d&#039;impression maximale sugg\u00e9r\u00e9e \u00e0 300 ppp. D\u00e9cocher R\u00e9\u00e9chantillonner ne modifie pas les pixels\u00a0; il s&#039;agit d&#039;une action d&#039;affichage uniquement.<\/p>\n<h3>Q : Une r\u00e9solution plus \u00e9lev\u00e9e est-elle toujours meilleure ?
