Windows Forms: Print Picture Box in C#

To play the demo, you should drag the PictureBox and Button controls from the visual studio toolbox to your winform, then layout your form as shown below.

Adding a click event handler to the Open button allows you to select an image, then display on the PictureBox control.

private void btnOpen_Click(object sender, EventArgs e)
{
    //Open image file
    using (OpenFileDialog ofd = new OpenFileDialog() { Filter = "JPEG|*.jpg", ValidateNames = true })
    {
        if (ofd.ShowDialog() == DialogResult.OK)
            pictureBox.Image = Image.FromFile(ofd.FileName);
    }
}

Adding a click event handler to the Print button allows you to print an image from the PictureBox as the following c# code.

private void btnPrint_Click(object sender, EventArgs e)
{
    //Show print dialog
    PrintDialog pd = new PrintDialog();
    PrintDocument doc = new PrintDocument();
    doc.PrintPage += Doc_PrintPage;
    pd.Document = doc;
    if (pd.ShowDialog() == DialogResult.OK)
        doc.Print();
}

Creating the PrintPage event handler allows you to print an image using PrintDocument to the printer.

private void Doc_PrintPage(object sender, PrintPageEventArgs e)
{
    //Print image
    Bitmap bm = new Bitmap(pictureBox.Width, pictureBox.Height);
    pictureBox.DrawToBitmap(bm, new Rectangle(0, 0, pictureBox.Width, pictureBox.Height));
    e.Graphics.DrawImage(bm, 0, 0);
    bm.Dispose();
}

Through this c# example, you can easily print an image from the PictureBox in c# windows forms application.
