Print on an Intermec PM43 labeller

I have to print some barcodes on a label (which measures 4 x 3 inches), the barcodes I send them to a panel doing them with the library BarcodeLib, after reading a code this throws another that I have related to a database and display it in a panel with the following code

if (e.KeyChar == (char)Keys.Enter)
            {
                if (textBox1.Text != "")
                {
                    Barcode codigo = new Barcode();
                    codigo.IncludeLabel = true;

                    DataTable buscar = existente.busqueda(textBox1.Text, textBox1.Text);
                    if (buscar.Rows.Count > 0)
                    {
                        DataRow row = buscar.Rows[0];
                        etiquetaNombre = Convert.ToString(row["nombre"]);
                        panel1.BackgroundImage = codigo.Encode(TYPE.CODE128, etiquetaNombre, Color.Black, Color.White, 300, 99);
                        guardado = true;
                    }
                    else
                    {
                        panel1.BackgroundImage = codigo.Encode(TYPE.CODE128, Convert.ToString("No Existe"), Color.White, Color.White, 300, 99);
                        MessageBox.Show("No se encontro un nombre asociado a este numero " + textBox1.Text);
                        panel1.BackColor = Color.White;
                        textBox1.Text = "";
                    }

                }

            }

I do the same with a second panel that would have a quantity

Then with a button to print the panels that is as follows

            PrintDocument doc = new PrintDocument();
            doc.PrintPage += new PrintPageEventHandler(pd_PrintPage2);
            PrintDialog PrintSettings = new PrintDialog();
            PrintSettings.Document = doc;
            PageSettings pgsetting = new PageSettings();

            if (PrintSettings.ShowDialog() == DialogResult.OK)
                doc.Print();

Which sends for calling the following method

void pd_PrintPage2(object sender, PrintPageEventArgs e)
        {
            int w = e.MarginBounds.Width / 2;
            int x = e.MarginBounds.Left;
            int y = e.MarginBounds.Top;
            Font printFont = new Font("Code 128", 40);
            Bitmap logo = new Bitmap(panel1.Width, panel1.Height, panel1.CreateGraphics());
            panel1.DrawToBitmap(logo, new Rectangle(0, 0, panel1.Width, panel1.Height));
            Bitmap logo2 = new Bitmap(panel2.Width, panel2.Height, panel2.CreateGraphics());
            panel2.DrawToBitmap(logo2, new Rectangle(0, 0, panel2.Width, panel2.Height));
            int height = 100 + y;
            string tabDataText = textBox2.Text;
            var tabDataForeColor = Color.Black;
            var txtDataWidth = e.Graphics.MeasureString(tabDataText, printFont).Width;

            using (var sf = new StringFormat())
            {
                height += logo.Height + 15;
                sf.LineAlignment = StringAlignment.Center;
                sf.Alignment = StringAlignment.Center;
                e.Graphics.DrawString(tabDataText, new Font("bc39CR8", 40),
                     new SolidBrush(tabDataForeColor),
                     e.MarginBounds.Left + (e.MarginBounds.Width / 2),
                     e.MarginBounds.Top + (e.MarginBounds.Height / 2) + (logo.Height / 2) + 15,
                     sf);
            }

            e.Graphics.DrawImage(logo2,
                e.MarginBounds.Left + (e.MarginBounds.Width / 2) - (logo2.Width / 2),
                e.MarginBounds.Top + (e.MarginBounds.Height / 2) - (logo2.Height));

            e.Graphics.DrawImage(logo,
               e.MarginBounds.Left + (e.MarginBounds.Width / 2) - (logo.Width / 2),
                e.MarginBounds.Top + (e.MarginBounds.Height / 2) - (logo.Height));

            e.HasMorePages = false;
        }
    }

But with this code it only prints one of the bar codes, and the other one seems not to take it into account, so I did it with a text with a source to do it bar code but I want to know if there is a better way to do it and also be able to write on top of each barcode what is as name and quantity
