Print Files from C# Code: Step-by-Step Guide

Printing files from C# code can be a useful feature for any application that needs to generate reports, receipts, or other types of documents. In this step-by-step guide, we'll go through the process of printing files from C# code.

Step 1: Add System.Drawing.Printing Namespace

Before we can start printing files from our C# code, we need to add the System.Drawing.Printing namespace to our project. This namespace provides classes that allow us to control the printing process.

using System.Drawing.Printing;

Step 2: Create a PrintDocument Object

Next, we need to create a PrintDocument object. This object represents the document that we want to print. We can set various properties of the PrintDocument object, such as the document name, the printer to use, and the page orientation.

PrintDocument pd = new PrintDocument();

Step 3: Set PrintPage Event Handler

We need to set the PrintPage event handler for our PrintDocument object. This event handler is called each time a page is printed. Inside the event handler, we can draw the content that we want to print on the page.

pd.PrintPage += new PrintPageEventHandler(PrintPage);

Step 4: Implement PrintPage Event Handler

In the PrintPage event handler, we can use the Graphics object to draw the content that we want to print on the page. We can use methods such as DrawString, DrawImage, and DrawRectangle to draw text, images, and shapes on the page.

private void PrintPage(object sender, PrintPageEventArgs e)
{
    // Draw content on page using e.Graphics object
}

Step 5: Print the Document

Finally, we can print the document by calling the Print method of the PrintDocument object. We can also display a PrintDialog to allow the user to select a printer and set print options.

PrintDialog pdialog = new PrintDialog();
if (pdialog.ShowDialog() == DialogResult.OK)
{
    pd.PrinterSettings = pdialog.PrinterSettings;
    pd.Print();
}

Conclusion

Printing files from C# code can be achieved by following these simple steps. By using the System.Drawing.Printing namespace and the PrintDocument object, we can easily control the printing process and generate high-quality documents from our C# applications.
