using IronPdf;

// Initialize a new instance of ChromePdfRenderer.
ChromePdfRenderer Renderer = new ChromePdfRenderer();

// Render the specified URL as a PDF document.
PdfDocument Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");

using IronPdf;

// Initialize a new instance of ChromePdfRenderer.
ChromePdfRenderer Renderer = new ChromePdfRenderer();

// Render the specified URL as a PDF document.
PdfDocument Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");

Imports IronPdf

' Initialize a new instance of ChromePdfRenderer.
Private Renderer As New ChromePdfRenderer()

' Render the specified URL as a PDF document.
Private Pdf As PdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/")

// Print the PDF document using the default printer settings.
Pdf.Print();

// Print the PDF document using the default printer settings.
Pdf.Print();

' Print the PDF document using the default printer settings.
Pdf.Print()

Advanced Printing Options

For silent printing, IronPDF provides various advanced printing options.

PdfDocument.GetPrintDocument method is used, and the result is stored in System.Drawing.Printing.PrintDocument object. The code is simple and as following:

// Remember to add assembly reference to System.Drawing.dll in project

// Get the print document for the PDF.
System.Drawing.Printing.PrintDocument PrintPDF = Pdf.GetPrintDocument();

// Remember to add assembly reference to System.Drawing.dll in project

// Get the print document for the PDF.
System.Drawing.Printing.PrintDocument PrintPDF = Pdf.GetPrintDocument();

' Remember to add assembly reference to System.Drawing.dll in project

' Get the print document for the PDF.
Dim PrintPDF As System.Drawing.Printing.PrintDocument = Pdf.GetPrintDocument()

Specify Printer Name

IronPDF also gives the opportunity to print to a specific printer. To specify the name, the PrinterSettings.PrinterName property is used. First, we need to get the current PDF document object. Przykładowy kod wygląda następująco:

using (var printDocument = pdfDocument.GetPrintDocument())
{
    // Specify the printer name.
    printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF";

    // Send the print job to the specified printer.
    printDocument.Print();
}

using (var printDocument = pdfDocument.GetPrintDocument())
{
    // Specify the printer name.
    printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF";

    // Send the print job to the specified printer.
    printDocument.Print();
}

Using printDocument = pdfDocument.GetPrintDocument()
	' Specify the printer name.
	printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF"

	' Send the print job to the specified printer.
	printDocument.Print()
End Using

Set Printer Resolution

Another cool feature is setting the printer resolution. We can control the number of pixels to be printed, displayed, depending on the output. The DefaultPageSettings.PrinterResolution property of the PDF document can be used to set the resolution. Here is a very quick code sample:

// Set the custom resolution for the printer.
printDocument.DefaultPageSettings.PrinterResolution = new PrinterResolution
{
    Kind = PrinterResolutionKind.Custom,
    X = 1200,
    Y = 1200
};

// Send the print job with the custom resolution settings.
printDocument.Print();

// Set the custom resolution for the printer.
printDocument.DefaultPageSettings.PrinterResolution = new PrinterResolution
{
    Kind = PrinterResolutionKind.Custom,
    X = 1200,
    Y = 1200
};

// Send the print job with the custom resolution settings.
printDocument.Print();

' Set the custom resolution for the printer.
printDocument.DefaultPageSettings.PrinterResolution = New PrinterResolution With {
	.Kind = PrinterResolutionKind.Custom,
	.X = 1200,
	.Y = 1200
}

' Send the print job with the custom resolution settings.
printDocument.Print()

PrintToFile Method

The PdfDocument class provides the PrintToFile method which allows us to print PDF to a file in C#. It takes the pathToFile as an argument to print the file directly to that location without opening the printer dialog. Kod jest prosty i wygląda następująco:

// Print the document to a specified file location.
printDocument.PrintToFile("PathToFile", false);

// Print the document to a specified file location.
printDocument.PrintToFile("PathToFile", false);

' Print the document to a specified file location.
printDocument.PrintToFile("PathToFile", False)

The complete code example goes as follows:

using IronPdf;

// Initialize the PDF renderer and create the PDF document.
ChromePdfRenderer Renderer = new ChromePdfRenderer();
PdfDocument pdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/");

using (var printDocument = pdfDocument.GetPrintDocument())
{
    // Specify the printer name.
    printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF";

    // Set a custom print resolution.
    printDocument.DefaultPageSettings.PrinterResolution = new PrinterResolution
    {
        Kind = PrinterResolutionKind.Custom,
        X = 1200,
        Y = 1200
    };

    // Execute the print job.
    printDocument.Print();
}

using IronPdf;

// Initialize the PDF renderer and create the PDF document.
ChromePdfRenderer Renderer = new ChromePdfRenderer();
PdfDocument pdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/");

using (var printDocument = pdfDocument.GetPrintDocument())
{
    // Specify the printer name.
    printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF";

    // Set a custom print resolution.
    printDocument.DefaultPageSettings.PrinterResolution = new PrinterResolution
    {
        Kind = PrinterResolutionKind.Custom,
        X = 1200,
        Y = 1200
    };

    // Execute the print job.
    printDocument.Print();
}

Imports IronPdf

' Initialize the PDF renderer and create the PDF document.
Private Renderer As New ChromePdfRenderer()
Private pdfDocument As PdfDocument = Renderer.RenderUrlAsPdf("https://ironpdf.com/")

Using printDocument = pdfDocument.GetPrintDocument()
	' Specify the printer name.
	printDocument.PrinterSettings.PrinterName = "Microsoft Print to PDF"

	' Set a custom print resolution.
	printDocument.DefaultPageSettings.PrinterResolution = New PrinterResolution With {
		.Kind = PrinterResolutionKind.Custom,
		.X = 1200,
		.Y = 1200
	}

	' Execute the print job.
	printDocument.Print()
End Using

When the code is executed, it converts a URL to a PDF document. Then to silently print a PDF document, the GetPrintDocument method is used. On successful compiling and executing the program files, a printer dialog box appears to save it as a PDF document. The PDF is then saved using the specified printer name.
