使用 PDF 打印 - 外观

将 PDF 文件打印到默认打印机，使用打印机和页面设置

首先，将文档转换为图像，然后在打印机上打印。 创建一个 PdfViewer 类的实例，该实例可以将 PDF 文件打印到默认打印机，使用 BindPdf 方法将文档打开，并更改必要的设置。此示例使用 A4 格式，纵向方向。在 PrinterSettings 中，首先应设置打印的打印机名称。否则，它将打印到默认打印机。接下来，填写所需的副本数量。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PrintingPDFFile()
{
    // 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);
    }
}

    // 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);
}

为了显示打印对话框，请使用以下代码片段：

.NET Core 3.1

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

    // 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;

        var printDialog = new System.Windows.Forms.PrintDialog();
        if (printDialog.ShowDialog() == DialogResult.OK)
        {
            // Document printing code goes here

            // Convert PrinterSettings and PageSettings to Aspose.PDF counterparts via extension methods
            // provided in the Aspose.Pdf.Printing namespace
            Aspose.Pdf.Printing.PrinterSettings ps = printDialog.PrinterSettings.ToAsposePrinterSettings();
            Aspose.Pdf.Printing.PageSettings pgs = printDialog.PrinterSettings.DefaultPageSettings.ToAsposePageSettings();

            // Print document using printer and page settings

    }
}

将 PDF 打印到虚拟打印机

有些打印机可以打印到文件。要使用它们，请设置虚拟打印机的名称，并类似于前面的示例，进行设置。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PrintingPDFToSoftPrinter()
{
    // 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;
        // Do not convert document pages to images
        viewer.PrintAsImage = false;

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

        // Set printer name
        ps.PrinterName = "HP Universal Printing PS (v7.0.0)";
        // Or set the PDF printer
        // ps.PrinterName = "Adobe PDF";

        // 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);
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PrintingPDFToSoftPrinter()

    // 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;
    // Do not convert document pages to images
    viewer.PrintAsImage = false;

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

    // Set printer name
    ps.PrinterName = "HP Universal Printing PS (v7.0.0)";
    // Or set the PDF printer
    // ps.PrinterName = "Adobe PDF";

    // 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);
}

    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
        var ps = new Aspose.Pdf.Printing.PrinterSettings();
        var pgs = new Aspose.Pdf.Printing.PageSettings();

        // Set XPS/PDF printer name
        ps.PrinterName = "OneNote for Windows 10";

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

        // Set PageMargins (if required)

    // 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;
        // Print the file as grayscale
        viewer.PrintAsGrayscale = false;

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

    // 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;
        // Do not convert document pages to images
        viewer.PrintAsImage = false;

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

        // Set printer name
        ps.PrinterName = "HP Universal Printing PS (v7.0.0)";
        
        // Set output file name and PrintToFile attribute
        ps.PrintFileName = dataDir + "PdfToPostScript_out.ps";
        ps.PrintToFile = true;

        // 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);
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void PrintingPDFToSoftPrinter()
{
    // 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;
    // Do not convert document pages to images
    viewer.PrintAsImage = false;

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

    // Set printer name
    ps.PrinterName = "HP Universal Printing PS (v7.0.0)";
    
    // Set output file name and PrintToFile attribute
    ps.PrintFileName = dataDir + "PdfToPostScript_out.ps";
    ps.PrintToFile = true;

    // 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);
}

检查打印作业状态

PDF 文件可以打印到物理打印机，也可以打印到 Microsoft XPS Document Writer，而无需显示打印对话框，使用 PdfViewer 类。当打印大型 PDF 文件时，过程可能需要很长时间，因此用户可能不确定打印过程是否完成或遇到问题。要确定打印作业的状态，请使用 PrintStatus 属性。以下代码片段演示了如何将 PDF 文件打印到 XPS 文件并获取打印状态。

.NET Core 3.1

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

    // Instantiate 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;
        // Do not convert document pages to images
        viewer.PrintAsImage = false;

        // Create Printer Settings object
        var ps = new Aspose.Pdf.Printing.PrinterSettings();
        var pgs = new Aspose.Pdf.Printing.PageSettings();

        // Specify the printer name
        ps.PrinterName = "Microsoft XPS Document Writer";

        // Set output file name and PrintToFile attribute
        ps.PrintFileName = dataDir + "CheckingPrintJobStatus_out.xps";
        ps.PrintToFile = true;

        // 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);

        // Check the print status
        if (viewer.PrintStatus != null)
        {
            // An exception was thrown
            if (viewer.PrintStatus is Exception ex)
            {
                // Get exception message
                Console.WriteLine(ex.Message);
            }
        }
        else
        {
            // No errors were found. Printing job has completed successfully
            Console.WriteLine("Printing completed without any issue.");
        }
    }
}

.NET 8

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

    // Instantiate 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;
    // Do not convert document pages to images
    viewer.PrintAsImage = false;

    // Create Printer Settings object
    var ps = new Aspose.Pdf.Printing.PrinterSettings();
    var pgs = new Aspose.Pdf.Printing.PageSettings();

    // Specify the printer name
    ps.PrinterName = "Microsoft XPS Document Writer";

    // Set output file name and PrintToFile attribute
    ps.PrintFileName = dataDir + "CheckingPrintJobStatus_out.xps";
    ps.PrintToFile = true;

    // 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);

    // Check the print status
    if (viewer.PrintStatus != null)
    {
        // An exception was thrown
        if (viewer.PrintStatus is Exception ex)
        {
            // Get exception message
            Console.WriteLine(ex.Message);
        }
    }
    else
    {
        // No errors were found. Printing job has completed successfully
        Console.WriteLine("Printing completed without any issue.");
    }
}

在单面和双面模式下打印页面

在特定的打印作业中，PDF 文档的页面可以以双面或单面模式打印，但在单个打印作业中不能将某些页面打印为单面而某些页面打印为双面。然而，为了实现这一要求，可以使用不同的页面范围和 PrintingJobSettings 对象。以下代码片段演示了如何在单面模式下打印 PDF 文件的某些页面，而在双面模式下打印其他页面。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
struct PrintingJobSettings
{

在单个打印作业中打印多个 PDF 文档

有时，需要将多个相关文档作为单个打印作业一起打印。这确保这些文档不会与其他用户的输出交错，特别是在远程网络打印机上。Aspose.PDF 支持通过 PdfViewer 类的静态 PrintDocuments 方法在单个打印作业中打印任意数量的文档，使用共享的打印机设置。要打印的文档可以作为文件路径、文档流或 Document 对象提供。

在打印多个文档时， PrinterSettings.PrintRange 属性将被忽略，所有文档将全部打印。
