I work in visual studio 2015 windows form application and i need to print qr code by using c#

How can i print qr code generation ?

I generated using the following code :

if (textBox1.Text =="")
{
MessageBox.Show("Please Enter Value ","Error");
textBox1.Focus();
}
else
{
using (SaveFileDialog sv = new SaveFileDialog() { Filter = "JPEG|.jpg", ValidateNames = true })
{
if (sv.ShowDialog() == DialogResult.OK)
{
MessagingToolkit.QRCode.Codec.QRCodeEncoder encoder = new MessagingToolkit.QRCode.Codec.QRCodeEncoder();
encoder.QRCodeScale = 8;
string encoding="UserName : " + textBox1.Text + "\r\n" + "CardNo : " + textBox2.Text + "\r\n" + "Address:" + textBox3.Text + "\r\n"+textBox5.Text;
Bitmap bmp = encoder.Encode(encoding);
pictureBox1.Image = bmp;
bmp.Save(sv.FileName, ImageFormat.Jpeg);
}
}
}
}

Im sorry i posted this in asp.net forum by wrong .

Hi, Create one private variable file_name on top the function and assign sv.Filename to file_name. string file_name; using(SaveFileDialog sv =) { //your logic file_name = sv.FileName; } now file_name has path

After saving the QRCode image, print the image using below code:
private void button1_Click(object sender, EventArgs e)
{
    string fileName = @"D:\Development\QRCodeImage.jpeg"; //pass image file path
    var p = new Process();
    p.StartInfo.FileName = fileName;
    p.StartInfo.Verb = "Print";
    p.Start();
}
