            // Configure printer setting
            PrintSettings printSettings = new PrintSettings();
            printSettings.Dpi = 220;
            printSettings.NumberOfCopies = 10;
            printSettings.PaperOrientation = PaperOrientation.Portrait;

            // Print the document
            Printer.Print("awesomeIronPrint.pdf", printSettings);
        }
    }
}

using IronPrint;

namespace IronPrintDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            // Configure printer setting
            PrintSettings printSettings = new PrintSettings();
            printSettings.Dpi = 220;
            printSettings.NumberOfCopies = 10;
            printSettings.PaperOrientation = PaperOrientation.Portrait;

            // Print the document
            Printer.Print("awesomeIronPrint.pdf", printSettings);
        }
    }
}

Imports IronPrint

Namespace IronPrintDemo
	Friend Class Program
		Shared Sub Main(ByVal args() As String)
			' Configure printer setting
			Dim printSettings As New PrintSettings()
			printSettings.Dpi = 220
			printSettings.NumberOfCopies = 10
			printSettings.PaperOrientation = PaperOrientation.Portrait

			' Print the document
			Printer.Print("awesomeIronPrint.pdf", printSettings)
		End Sub
	End Class
End Namespace

System.Printing

The System.Printing namespace in C# contains classes and interfaces that enable developers to interact with printers, print queues, print servers, and print jobs programmatically. Some key classes and interfaces within this namespace include:

1. PrintQueue: Represents a printer or print device connected to the system.
2. PrintServer: Represents a print server on the network.
3. PrintSystemJobInfo: Provides information about a print job, such as its status and properties.
4. PrintTicket: Represents the settings for a print job, including paper size, orientation, and print quality.

Getting Started with System.Printing: Before we dive into the code, let's ensure that we have a basic understanding of how printing works with System.Printing:

1. PrintQueue Selection: You need to identify the PrintQueue object representing the printer you want to use for printing.
2. PrintTicket Configuration: Optionally, you can configure the PrintTicket object to specify print settings such as paper size, orientation, and number of copies.
3. Document Printing: Finally, you send the document to be printed to the selected PrintQueue.

Implementing Document Printing with System.Printing: Now, let's walk through the process of printing a document using System.Printing with the following example:

Here is the source code:

using System;
using System.IO;
using System.Printing;

class Program
{
    static void Main(string[] args)
    {
        // Specify the path to the document to be printed on the local printer
        string documentPath = "path/to/your/document.pdf";

        // Instantiate a Printer Server object representing the local print server
        using (PrintServer printServer = new PrintServer())
        {
            // Get the default PrintQueue from the PrintServer default 
            PrintQueue defaultPrintQueue = printServer.DefaultPrintQueue;

            // Create a PrintTicket object to specify print settings (optional)
            PrintTicket printTicket = new PrintTicket();

            // Configure print settings, e.g., number of copies
            printTicket.CopyCount = 1;

            // Print the document to the default PrintQueue with the specified PrintTicket
            defaultPrintQueue.AddJob("MyPrintJob", documentPath, false, printTicket);
        }

        Console.WriteLine("Document sent to print queue.");
    }
}

using System;
using System.IO;
using System.Printing;

class Program
{
    static void Main(string[] args)
    {
        // Specify the path to the document to be printed on the local printer
        string documentPath = "path/to/your/document.pdf";

        // Instantiate a Printer Server object representing the local print server
        using (PrintServer printServer = new PrintServer())
        {
            // Get the default PrintQueue from the PrintServer default 
            PrintQueue defaultPrintQueue = printServer.DefaultPrintQueue;

            // Create a PrintTicket object to specify print settings (optional)
            PrintTicket printTicket = new PrintTicket();

            // Configure print settings, e.g., number of copies
            printTicket.CopyCount = 1;

            // Print the document to the default PrintQueue with the specified PrintTicket
            defaultPrintQueue.AddJob("MyPrintJob", documentPath, false, printTicket);
        }

        Console.WriteLine("Document sent to print queue.");
    }
}

Imports System
Imports System.IO
Imports System.Printing

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Specify the path to the document to be printed on the local printer
		Dim documentPath As String = "path/to/your/document.pdf"

		' Instantiate a Printer Server object representing the local print server
		Using printServer As New PrintServer()
			' Get the default PrintQueue from the PrintServer default 
			Dim defaultPrintQueue As PrintQueue = printServer.DefaultPrintQueue

			' Create a PrintTicket object to specify print settings (optional)
			Dim printTicket As New PrintTicket()

			' Configure print settings, e.g., number of copies
			printTicket.CopyCount = 1

			' Print the document to the default PrintQueue with the specified PrintTicket
			defaultPrintQueue.AddJob("MyPrintJob", documentPath, False, printTicket)
		End Using

		Console.WriteLine("Document sent to print queue.")
	End Sub
End Class

IronPrint Vs System.Printing

This table provides a quick overview of the features and characteristics of IronPrint and System.Printing, helping developers make informed decisions based on their specific requirements and platform targets.

Step 1: Create a New project for Printing Documents using IronPrint

IronPrint can also be installed using the command below:

Install-Package IronPrint

Step 3: List network printers available for printing documents

To list the printer names using IronPrint use the code below:

using System;
using System.Collections.Generic;
using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Get printer names using printer drivers
            List<string> printersName = Printer.GetPrinterNames();
            foreach (var printer in printersName)
            {
                Console.WriteLine(printer);
            }
        }
    }
}

using System;
using System.Collections.Generic;
using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Get printer names using printer drivers
            List<string> printersName = Printer.GetPrinterNames();
            foreach (var printer in printersName)
            {
                Console.WriteLine(printer);
            }
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports IronPrint

Namespace IronPrintDemo
	Public Class Program
		Public Shared Sub Main()
			' Get printer names using printer drivers
			Dim printersName As List(Of String) = Printer.GetPrinterNames()
			For Each printer In printersName
				Console.WriteLine(printer)
			Next printer
		End Sub
	End Class
End Namespace

Step 4: Print PDF document using IronPrint

Use the code below to print the document silently:

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Print the document silently
            Printer.Print("sample.pdf");
        }
    }
}

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Print the document silently
            Printer.Print("sample.pdf");
        }
    }
}

Imports IronPrint

Namespace IronPrintDemo
	Public Class Program
		Public Shared Sub Main()
			' Print the document silently
			Printer.Print("sample.pdf")
		End Sub
	End Class
End Namespace

After the execution, the document is added to the print queue as shown in the output.

Step 5: Print PDF document using IronPrint with Dialog

Use the code below to print the document with the dialog:

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Print with Dialog
            Printer.ShowPrintDialog("sample.pdf");
        }
    }
}

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Print with Dialog
            Printer.ShowPrintDialog("sample.pdf");
        }
    }
}

Imports IronPrint

Namespace IronPrintDemo
	Public Class Program
		Public Shared Sub Main()
			' Print with Dialog
			Printer.ShowPrintDialog("sample.pdf")
		End Sub
	End Class
End Namespace

Step 6: Advanced Printing with Print settings

Printing documents with advanced settings is supported in IronPrint. It supports the following Properties:

1. PaperSize: Specifies the paper dimensions utilized by the printer.
2. PaperOrientation: Defines the orientation of the paper, such as Automatic, Portrait, or Landscape.
3. DPI: Sets the desired print resolution in dots per inch. The default value is 300, commonly employed in commercial printing. The actual DPI may be constrained by the printer's capabilities.
4. NumberOfCopies: Indicates the number of identical copies to print for a document.
5. PrinterName: Specifies the name of the printer designated for printing tasks.
6. PaperMargins: Determines the margins for printing, measured in millimeters.
7. Grayscałe: A boolean value determining whether to print in grayscałe. Domyślną wartością jest false.

Now let's look at a code example:

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Configure custom print settings
            PrintSettings printSettings = new PrintSettings();
            printSettings.Dpi = 150;
            printSettings.NumberOfCopies = 2;
            printSettings.PaperOrientation = PaperOrientation.Portrait;

            // Print the required document
            Printer.Print("sample.pdf", printSettings);
        }
    }
}

using IronPrint;

namespace IronPrintDemo
{
    public class Program
    {
        public static void Main()
        {
            // Configure custom print settings
            PrintSettings printSettings = new PrintSettings();
            printSettings.Dpi = 150;
            printSettings.NumberOfCopies = 2;
            printSettings.PaperOrientation = PaperOrientation.Portrait;

            // Print the required document
            Printer.Print("sample.pdf", printSettings);
        }
    }
}

Imports IronPrint

Namespace IronPrintDemo
	Public Class Program
		Public Shared Sub Main()
			' Configure custom print settings
			Dim printSettings As New PrintSettings()
			printSettings.Dpi = 150
			printSettings.NumberOfCopies = 2
