Good morning

I have a simple program that generate qrcode placed in picture box and save it to specific path as jpg.file.
My question is how can i send this file to thermal printer to print.

What I have tried:

txtQRCode.Text = textBox6.Text + textBox2.Text + textBox7.Text + textBox3.Text + textBox4.Text + textBox5.Text;
                            QRCodeGenerator qr = new QRCodeGenerator();
                            QRCodeData data = qr.CreateQrCode(txtQRCode.Text, QRCodeGenerator.ECCLevel.Q);
                            QRCode code = new QRCode(data);
                            pic.Image = code.GetGraphic(5);
                            pic.Image.Save(@"C:\Algo\2.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

Any program that can read a .jpg file will most likely have a print option.

Depends on the driver (and utilities) that come with the thermal printer and the "printer codes / language" it supports. Read the manual for the printer; it's not "plug and play" in my experience; most of these things hark back to XP.
