Now, let us consider an example to demonstrate how we can print a PDF file in C# using the IronPDF Library.

Open Program.cs file. Add the following namespace at the top of the Program.cs file to use IronPDF:

using IronPdf;

using IronPdf;

Imports IronPdf

Now, write the following code inside the Main function:

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Load the PDF document from file
        using PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

        // Print the loaded PDF document to the default printer
        pdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
        Konsola.ReadKey();
    }
}

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Load the PDF document from file
        using PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

        // Print the loaded PDF document to the default printer
        pdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
        Konsola.ReadKey();
    }
}

Imports System ' Required for Konsola operations

Class Program
    Shared Sub Main()
        ' Load the PDF document from file
        Using pdfDocument As PdfDocument = PdfDocument.FromFile("D:\Sample.pdf")
            ' Print the loaded PDF document to the default printer
            pdfDocument.Print()
        End Using

        ' Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!")
        Konsola.ReadKey()
    End Sub
End Class

Let's understand the code.

• The following line of code will load the PDF file into memory. "Sample.Pdf" is the file name and D Drive is my file location. You have to write a complete file path along with the file name.

using PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

using PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

Using pdfDocument As PdfDocument = PdfDocument.FromFile("D:\Sample.pdf")
End Using

• The Print() function will print the loaded file using your default printer.

I will show you how to print multiple PDF documents in C# using IronPDF.

14 PDF files

In this example, I have 14 PDF documents which I need to print. I have named them as numbers 1 - 14. You can save all your files with an ID, or you can save the file location in a database. Extract the file Path and Filename from the database, and save them in an array or on a list. Iterate that array or list and get all your files printed.

Write the following code inside the Main function:

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Loop through each file number and print
        for (int i = 1; i <= 14; i++)
        {
            // Load each PDF document from file
            using PdfDocument pdfDocument = PdfDocument.FromFile($@"D:\Print\{i}.pdf");

            // Inform which file is being printed
            Konsola.WriteLine("Printing File: {0}.pdf", i);

            // Print the loaded PDF document to the default printer
            pdfDocument.Print();

            // Print operation success message to console
            Konsola.WriteLine("{0}.pdf Printed Successfully!", i);
        }

        Konsola.ReadKey();
    }
}

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Loop through each file number and print
        for (int i = 1; i <= 14; i++)
        {
            // Load each PDF document from file
            using PdfDocument pdfDocument = PdfDocument.FromFile($@"D:\Print\{i}.pdf");

            // Inform which file is being printed
            Konsola.WriteLine("Printing File: {0}.pdf", i);

            // Print the loaded PDF document to the default printer
            pdfDocument.Print();

            // Print operation success message to console
            Konsola.WriteLine("{0}.pdf Printed Successfully!", i);
        }

        Konsola.ReadKey();
    }
}

Imports System ' Required for Konsola operations

Class Program
    Shared Sub Main()
        ' Loop through each file number and print
        For i As Integer = 1 To 14
            ' Load each PDF document from file
            Using pdfDocument As PdfDocument = PdfDocument.FromFile($"D:\Print\{i}.pdf")
                ' Inform which file is being printed
                Konsola.WriteLine("Printing File: {0}.pdf", i)

                ' Print the loaded PDF document to the default printer
                pdfDocument.Print()

                ' Print operation success message to console
                Konsola.WriteLine("{0}.pdf Printed Successfully!", i)
            End Using
        Next

        Konsola.ReadKey()
    End Sub
End Class

I have used a for loop to generate Numbers from 1 to 14 according to my file name.

I will show you how to print a web page by parsing URLs to IronPDF. The library will create a PDF file by parsing HTML. We can print that PDF document using the print function. Let's consider an example.

Write the following code inside the main function:

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // HTML to PDF Renderer
        IronPdf.HtmlToPdf Renderer = new IronPdf.HtmlToPdf();

        // Inform about the printing operation
        Konsola.WriteLine("Printing File");

        // Render URL as PDF
        using PdfDocument PdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/how-to/print-pdf/#advanced-printing");

        // Print the PDF document
        PdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
    }
}

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // HTML to PDF Renderer
        IronPdf.HtmlToPdf Renderer = new IronPdf.HtmlToPdf();

        // Inform about the printing operation
        Konsola.WriteLine("Printing File");

        // Render URL as PDF
        using PdfDocument PdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/how-to/print-pdf/#advanced-printing");

        // Print the PDF document
        PdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
    }
}

Imports System ' Required for Konsola operations

Class Program
    Shared Sub Main()
        ' HTML to PDF Renderer
        Dim Renderer As New IronPdf.HtmlToPdf()

        ' Inform about the printing operation
        Konsola.WriteLine("Printing File")

        ' Render URL as PDF
        Using PdfDocument As PdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/how-to/print-pdf/#advanced-printing")
            ' Print the PDF document
            PdfDocument.Print()
        End Using

        ' Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!")
    End Sub
End Class

This program will parse https://ironpdf.com/how-to/print-pdf/#advanced-printing to PDF and the Print() function will print the PDF using the default printer.

Let's run the program.

Run the Program:

Press Ctrl + F5 to run the solution.

Output displayed on screen

The Print() function will print the document using the default printer. There may be a situation where we do not want to use the default printer. In that case, IronPDF provides us with one line code to change the printer name.

Change Printer Name:

Let's use an example to help us understand further. Use the following code to change the default printer:

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Load the PDF document from file
        PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

        // Change to a different printer by name
        pdfDocument.GetPrintDocument().PrinterSettings.PrinterName = "Microsoft Print to PDF";

        // Print the PDF document
        pdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
    }
}

using System; // Required for Konsola operations

class Program
{
    static void Main()
    {
        // Load the PDF document from file
        PdfDocument pdfDocument = PdfDocument.FromFile(@"D:\Sample.pdf");

        // Change to a different printer by name
        pdfDocument.GetPrintDocument().PrinterSettings.PrinterName = "Microsoft Print to PDF";

        // Print the PDF document
        pdfDocument.Print();

        // Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!");
    }
}

Imports System ' Required for Konsola operations

Class Program
    Shared Sub Main()
        ' Load the PDF document from file
        Dim pdfDocument As PdfDocument = PdfDocument.FromFile("D:\Sample.pdf")

        ' Change to a different printer by name
        pdfDocument.GetPrintDocument().PrinterSettings.PrinterName = "Microsoft Print to PDF"

        ' Print the PDF document
        pdfDocument.Print()

        ' Print operation success message to console
        Konsola.WriteLine("File Printed Successfully!")
    End Sub
End Class

You can see that I have added only one line of additional code to specify the printer. I have specified Microsoft Print to PDF for demonstration.

Run the Program:

Run the Program by pressing Ctrl + F5.

The following Dialogue Box will appear that will ask us to enter a file name to save because we are using Microsoft Print to PDF.

Specify the File name and click on the Save button. I have specified "SamplePrint.Pdf". The following console output will display:

Microsoft Print to PDF has printed a PDF file in my D Drive. Let's see it.
