Cetak File Pdf di C# - Cetak File PDF ke Printer Default menggunakan Pengaturan Printer dan Halaman

Artikel ini menjelaskan cara Mencetak File PDF ke Printer Default menggunakan Pengaturan Printer dan Halaman di C#.

Kelas PdfViewer memungkinkan Anda untuk mencetak file PDF ke printer default. Anda perlu membuat objek PdfViewer dan membuka PDF menggunakan metode BindPdf. Untuk menentukan pengaturan cetak yang berbeda, gunakan kelas PageSettings dan PrinterSettings. Terakhir, panggil metode PrintDocumentWithSettings untuk mencetak PDF ke printer default. Potongan kode berikut menunjukkan cara mencetak PDF ke printer default dengan pengaturan printer dan halaman.

.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)
        pgs.PaperSize = Aspose.Pdf.Printing.PaperSizes.A4;

        // Set PageMargins (if required)
        pgs.Margins = new Aspose.Pdf.Devices.Margins(0, 0, 0, 0);

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

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

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

    // Set PageSize (if required)
    pgs.PaperSize = Aspose.Pdf.Printing.PaperSizes.A4;

    // Set PageMargins (if required)
    pgs.Margins = new Aspose.Pdf.Devices.Margins(0, 0, 0, 0);

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

Memilih sumber kertas berdasarkan ukuran halaman PDF

Sejak rilis 24.4, memilih sumber kertas berdasarkan ukuran halaman PDF di dialog cetak adalah mungkin. Potongan kode berikut memungkinkan pemilihan baki printer berdasarkan ukuran halaman PDF.

Preferensi ini dapat dihidupkan dan dimatikan menggunakan properti 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");
