Spécifiez la sortie à imprimer en gérant l'événement PrintPage et en utilisant Graphics inclus dans PrintPageEventArgs.
Utilisez la propriété PrinterSettings..::.PrinterName pour spécifier l'imprimante à utiliser pour imprimer le document.
La méthode Print imprime le document sans utiliser une boîte de dialogue d'impression. Utilisez PrintDialog lorsque vous souhaitez donner à l'utilisateur la possibilité de choisir les paramètres d'impression.
Remarque : |
|---|
Si une exception qui n'est pas gérée par la méthode Print est levée pendant l'impression, l'impression du document est abandonnée. |
Dans l'exemple de code suivant, le fichier spécifié dans la ligne de commande est imprimé sur l'imprimante par défaut.
Remarque : |
|---|
Il est nécessaire que chaque ligne corresponde à la largeur de page. |
Utilisez les espaces de noms System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO et System.Windows.Forms pour cet exemple.
