How to print a PDF using the PdfToImageConverter library

The Syncfusion Essential® PDF is a feature-rich and high-performance .NET PDF library used to create, read, and edit PDF documents programmatically without Adobe dependencies. Using this library, we can print a PDF using the PdfToImageConverter in C#.

Steps to print a PDF using the PdfToImageConverter programmatically:

1. Create a new console application project.
2. Install the Syncfusion.PdfToImageConverter.Net NuGet package as a reference to your console application from Nuget.org.
   
3. Include the following namespaces in the Program.cs file.

C#

using Syncfusion.PdfToImageConverter;
using System.Drawing;
using System.Drawing.Printing;

4. Use the following code sample in Program.cs to print a PDF using the PdfToImageConverter.
   C#

public class Program
{
   static int itr = 0;
   static Bitmap[] bitmaps;
   static void Main(string[] args)
   {
       // Initialize PDF to Image converter.
       PdfToImageConverter imageConverter = new PdfToImageConverter();
       // Load the PDF document as a stream
       FileStream inputStream = new FileStream("../../../Input.pdf", FileMode.Open, FileAccess.ReadWrite);
       imageConverter.Load(inputStream);
       bitmaps = new Bitmap[imageConverter.PageCount - 1];
       // Convert PDF to Image.
       Stream[] outputStream = imageConverter.Convert(0, imageConverter.PageCount - 1, false, false);
       bitmaps = BitmapConverter.ConvertStreamsToBitmaps(outputStream);
       PrintDocument printDocument = new PrintDocument();
       printDocument.PrintPage += PrintDocument_PrintPage;
       printDocument.Print();
   }

   private static void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)
   {
       e.Graphics.DrawImage(bitmaps[itr], 0, 0, e.PageBounds.Width, e.PageBounds.Height);
       e.HasMorePages = itr < bitmaps.Length - 1;
       itr = itr + 1;
   }
}

public class BitmapConverter
{
   public static Bitmap[] ConvertStreamsToBitmaps(Stream[] streams)
   {
       Bitmap[] bitmaps = new Bitmap[streams.Length];

       for (int i = 0; i < streams.Length; i++)
       {
           bitmaps[i] = new Bitmap(streams[i]);
       }

       return bitmaps;
   }
}

By executing the program, you will get the PDF document as follows.

Take a moment to peruse the documentation for working with images, where you will find other options like inserting, replacing image in PDF document, image pagination, and image masking.
