打印文档

静默打印

无需显示打印对话框即可无缝打印文档。然后可以直接在代码中设置打印参数。

// Programmatically print a document without showing the print dialog.
// Define your print job and settings here as needed.

using System;
using IronPrint;

public class SilentPrint
{
    public static void Main()
    {
        // Create a print document instance
        var document = new PrintDocument("sample-document.pdf");

        // Initialize a silent print job
        var printJob = new PrintJob(document);

        // Apply specific settings as necessary
        // For example: set printer name, copies, etc.
        
        // Execute the print job
        printJob.PrintSilently();
    }
}

// Programmatically print a document without showing the print dialog.
// Define your print job and settings here as needed.

using System;
using IronPrint;

public class SilentPrint
{
    public static void Main()
    {
        // Create a print document instance
        var document = new PrintDocument("sample-document.pdf");

        // Initialize a silent print job
        var printJob = new PrintJob(document);

        // Apply specific settings as necessary
        // For example: set printer name, copies, etc.
        
        // Execute the print job
        printJob.PrintSilently();
    }
}

Imports System
Imports IronPrint

Public Class SilentPrint
    Public Shared Sub Main()
        ' Create a print document instance
        Dim document As New PrintDocument("sample-document.pdf")

        ' Initialize a silent print job
        Dim printJob As New PrintJob(document)

        ' Apply specific settings as necessary
        ' For example: set printer name, copies, etc.

        ' Execute the print job
        printJob.PrintSilently()
    End Sub
End Class

Imports System
Imports IronPrint

Public Class SilentPrint
    Public Shared Sub Main()
        ' Create a print document instance
        Dim document As New PrintDocument("sample-document.pdf")

        ' Initialize a silent print job
        Dim printJob As New PrintJob(document)

        ' Apply specific settings as necessary
        ' For example: set printer name, copies, etc.

        ' Execute the print job
        printJob.PrintSilently()
    End Sub
End Class

带对话框的打印

在显示的打印设置对话框中启动打印过程。这样一来，用户可以交互式地自定义打印选项。

// Start a print job with user interaction through the print dialog.

using System;
using IronPrint;

public class DialogPrint
{
    public static void Main()
    {
        // Create a print document instance
        var document = new PrintDocument("sample-document.pdf");

        // Initialize a print job with dialog
        var printJob = new PrintJob(document);

        // Execute the print job with display of print options dialog
        printJob.PrintWithDialog();
    }
}

// Start a print job with user interaction through the print dialog.

using System;
using IronPrint;

public class DialogPrint
{
    public static void Main()
    {
        // Create a print document instance
        var document = new PrintDocument("sample-document.pdf");

        // Initialize a print job with dialog
        var printJob = new PrintJob(document);

        // Execute the print job with display of print options dialog
        printJob.PrintWithDialog();
    }
}

' Start a print job with user interaction through the print dialog.

Imports System
Imports IronPrint

Public Class DialogPrint
	Public Shared Sub Main()
		' Create a print document instance
		Dim document = New PrintDocument("sample-document.pdf")

		' Initialize a print job with dialog
		Dim printJob As New PrintJob(document)

		' Execute the print job with display of print options dialog
		printJob.PrintWithDialog()
	End Sub
End Class

' Start a print job with user interaction through the print dialog.

Imports System
Imports IronPrint

Public Class DialogPrint
	Public Shared Sub Main()
		' Create a print document instance
		Dim document = New PrintDocument("sample-document.pdf")

		' Initialize a print job with dialog
		Dim printJob As New PrintJob(document)

		' Execute the print job with display of print options dialog
		printJob.PrintWithDialog()
	End Sub
End Class

        var document = new PrintDocument("sample-document.pdf");

        // Create a print job
        var printJob = new PrintJob(document);

        // Set custom print settings like duplex, color mode, etc.
        var settings = new PrintSettings
        {
            ColorMode = ColorMode.Color,
            DuplexMode = DuplexMode.OneSided,
            Copies = 2
        };

        // Apply settings to print job
        printJob.ApplySettings(settings);

        // Print the document
        printJob.PrintSilently();
    }
}

// Example code to apply custom print settings programmatically.

using System;
using IronPrint;

public class PrintSettingsExample
