Imprimer un fichier PDF en C# - Imprimer un fichier PDF sur l’imprimante par défaut en utilisant les paramètres d’imprimante et de page

Cet article décrit comment imprimer un fichier PDF sur l’imprimante par défaut en utilisant les paramètres d’imprimante et de page en C#.

La classe PdfViewer vous permet d’imprimer un fichier PDF sur l’imprimante par défaut. Vous devez créer un objet PdfViewer et ouvrir le PDF en utilisant la méthode BindPdf. Pour spécifier différents paramètres d’impression, utilisez les classes PageSettings et PrinterSettings. Enfin, appelez la méthode PrintDocumentWithSettings pour imprimer le PDF sur l’imprimante par défaut. Le code suivant montre comment imprimer un PDF sur l’imprimante par défaut avec les paramètres d’imprimante et de page.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void SimplePrint()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PdfViewer object
    using (var viewer = new Aspose.Pdf.Facades.PdfViewer())
    {
        // Bind PDF document
        viewer.BindPdf(dataDir + "PrintDocument.pdf");

        // Set attributes for printing
        // Print the file with adjusted size
        viewer.AutoResize = true;
        // Print the file with adjusted rotation
        viewer.AutoRotate = true;
        // Do not produce the page number dialog when printing
        viewer.PrintPageDialog = false;

        // Create objects for printer and page settings and PrintDocument
        var ps = new Aspose.Pdf.Printing.PrinterSettings();
        var pgs = new Aspose.Pdf.Printing.PageSettings();
        var prtdoc = new System.Drawing.Printing.PrintDocument();

        // Set printer name
        ps.PrinterName = prtdoc.PrinterSettings.PrinterName;

        // Set PageSize (if required)

        // Print document using printer and page settings
        viewer.PrintDocumentWithSettings(pgs, ps);
    }
}

Choisir la source de papier par taille de page PDF

Depuis la version 24.4, il est possible de choisir la source de papier par taille de page PDF dans la boîte de dialogue d’impression. Le code suivant permet de choisir un bac d’imprimante en fonction de la taille de la page PDF.

Cette préférence peut être activée ou désactivée en utilisant la propriété Document.PickTrayByPdfSize.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PickTrayByPdfSize()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();
        page.Paragraphs.Add(new Aspose.Pdf.Text.TextFragment("Hello world!"));

        // Set the flag to choose a paper tray using the PDF page size
        document.PickTrayByPdfSize = true;

        // Save PDF document
        document.Save(dataDir + "PickTrayByPdfSize_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PickTrayByPdfSize()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_Printing();

    // Create PDF document
    using var document = new Aspose.Pdf.Document();

    // Add page
    var page = document.Pages.Add();
    page.Paragraphs.Add(new Aspose.Pdf.Text.TextFragment("Hello world!"));

    // Set the flag to choose a paper tray using the PDF page size
    document.PickTrayByPdfSize = true;

    // Save PDF document
    document.Save(dataDir + "PickTrayByPdfSize_out.pdf");
}
