Installing IronPDF

To start using IronPDF, follow these steps to install it using the NuGet Package Manager in Visual Studio:

1. Open Visual Studio and create a new Console Application or open an existing one.

   

2. Right-click on the project in the Solution Explorer and select "Manage NuGet Packages."

3. Switch to the "Browse" tab, search for "IronPDF," and click "Install."

   

With IronPDF successfully installed, we can begin using it for printing PDFs and other PDF document-related tasks. Before that, let's also install PDFiumViewer in our system.

Installing PDFiumViewer

You can install PDFiumViewer via the NuGet Package Manager as well. Here's how:

1. Open your Visual Studio project and create a Windows Forms application.

   

2. Drag a button to the Form and name it "Print PDF".

   

3. Right-click on the project in the Solution Explorer and choose "Manage NuGet Packages."

4. In the "NuGet Package Manager" window, switch to the "Browse" tab, search for "PDFiumViewer" and click "Install."

   

5. Alternatively, to install the PDFium DLL, you can search for "PDFiumViewer.Native" 32-bit or 64-bit, depending on your OS requirements. This DLL is necessary to load PDF files or pages using PDFiumViewer in a Windows Forms application.

   

Once the installation is complete, you can start using PDFiumViewer for printing PDF files and other PDF-related tasks.

Printing PDFs with IronPDF

Printing PDFs using IronPDF is straightforward. Here's the source code example demonstrating how to print a PDF file without a printer name:

using IronPdf;

class Program
{
    static void Main()
    {
        // Create a new PDF renderer
        var renderer = new ChromePdfRenderer();

        // Render a PDF from a URL
        PdfDocument pdf = renderer.RenderUrlAsPdf("https://ironpdf.com");

        // Print the PDF document, 300 dpi, without printer name
        pdf.Print(300, true);
    }
}

using IronPdf;

class Program
{
    static void Main()
    {
        // Create a new PDF renderer
        var renderer = new ChromePdfRenderer();

        // Render a PDF from a URL
        PdfDocument pdf = renderer.RenderUrlAsPdf("https://ironpdf.com");

        // Print the PDF document, 300 dpi, without printer name
        pdf.Print(300, true);
    }
}

Imports IronPdf

Friend Class Program
	Shared Sub Main()
		' Create a new PDF renderer
		Dim renderer = New ChromePdfRenderer()

		' Render a PDF from a URL
		Dim pdf As PdfDocument = renderer.RenderUrlAsPdf("https://ironpdf.com")

		' Print the PDF document, 300 dpi, without printer name
		pdf.Print(300, True)
	End Sub
End Class

In this code example, IronPDF efficiently renders a PDF from a URL and sends it to the default printer for printing. The method Print is configured for a resolution of 300 DPI, allowing silent printing without prompting the user. For more advanced printing options, please visit the C# Print PDF Documents.

Printing PDFs with PDFiumViewer

While PDFiumViewer excels in rendering and displaying PDFs, it doesn't provide native PDF printing capabilities. To print a PDF document using PDFiumViewer, you'll need to utilize additional third-party drawing tools or libraries. To print directly using PDFiumViewer, we need to use Microsoft's System.Drawing.Printing assembly along with the PDFiumViewer library.

In the following code, first, we load the PDF using the PdfDocument.Load method. Then, we create a printing object called printDocument using the CreatePrintDocument method, which comes from the System.Drawing.Printing namespace. Finally, we use the Print method to send the loaded PDF to the printer for printing.

using System;
using System.Drawing.Printing;
using PdfiumViewer;

class Program
{
    static void Main()
    {
        string pathToFile = @"C:\assets\input.pdf"; // Absolute path with filename

        // Load the PDF document
        using (var pdf = PdfDocument.Load(pathToFile))
        {
            // Create a print document for the loaded PDF
            var printDocument = pdf.CreatePrintDocument();

            // Print the document
            printDocument.Print();
        }
    }
}

using System;
using System.Drawing.Printing;
using PdfiumViewer;

class Program
{
    static void Main()
    {
        string pathToFile = @"C:\assets\input.pdf"; // Absolute path with filename

        // Load the PDF document
        using (var pdf = PdfDocument.Load(pathToFile))
        {
            // Create a print document for the loaded PDF
            var printDocument = pdf.CreatePrintDocument();

            // Print the document
            printDocument.Print();
        }
    }
}

Imports System
Imports System.Drawing.Printing
Imports PdfiumViewer

Friend Class Program
	Shared Sub Main()
		Dim pathToFile As String = "C:\assets\input.pdf" ' Absolute path with filename

		' Load the PDF document
		Using pdf = PdfDocument.Load(pathToFile)
			' Create a print document for the loaded PDF
			Dim printDocument = pdf.CreatePrintDocument()

			' Print the document
			printDocument.Print()
		End Using
	End Sub
End Class

Note: PDFiumViewer requires a System.Windows.Forms assembly to work; otherwise, it will throw an exception. This is because the PDFiumViewer library is designed to be used with Windows Forms applications. Ensure this task is performed in a valid Windows Forms application.

On executing the app, the Windows form is displayed with a "Print PDF" button. Upon clicking, the print dialog is displayed. Save the document as a PDF file.

The output is the same as the input PDF file. If the printer settings had the physical printer name, then it would have been printed out on paper perfectly.

Conclusion

IronPDF and PDFiumViewer both serve distinct purposes when it comes to working with PDFs. IronPDF offers a comprehensive set of features for creating, manipulating, and printing PDFs. Its ease of use and rich functionality make it a popular choice for .NET developers.

On the other hand, PDFiumViewer shines in rendering and displaying PDFs within Windows Forms applications. However, it lacks native PDF printing capabilities, and additional solutions for printing, as shown in the above example, may be required.

The choice between IronPDF and PDFiumViewer depends on your specific project requirements. If you need access to a versatile library with robust PDF manipulation features, IronPDF is an excellent choice. On the other hand, if your focus is on displaying PDFs in a Windows Forms application, PDFiumViewer can fulfill that role.

IronPDF is a powerful PDF library for C# developers. It is free for development purposes, and commercial licenses start at $799 for a single developer. There is also a free trial with full features and support, so you can try it out before buying. You can download the software from here.
