we have developed one software that is used some feature such as barcode. we use at previous zebra pritner. when zera barcode pritner hd broken we buy citizen cl7201e label printer .

Please share me knowledege of cl7201e pritner seeting and how to print from c# program use code 39 fonts for label?

Share me knowledge.
with best reagrd........

That is...incredibly specific. You'll have much better chances contacting the manufacturer. As for the actual printing, here's some snippets from a barcode assignment i did a while back. In no particular order...

#region member variables/consts
        bool[] bCode = new bool[95];    //barcode bit data array
        bool bValidCode = false;        //flag that indicates a valid code
        const double dPrintPenSize = 0.33, //size of printing pen (33mm)
                     dPrintHeight = 25.0,  //height of printing area (2.5cm)
                     dPrintXOffset = 50,   //offsets used when printing
                     dPrintYOffset = 50;
        const int iPrintWidth = 160,       //width of printing area
                  iXOffset = 6;            //X offset (padding)
        //handles the print event
        private void prntDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
            //set the page unit for printing
            e.Graphics.PageUnit = GraphicsUnit.Millimeter;
            //build the barcode on the page's graphics object
            BuildBarCode(e.Graphics, new Pen(Color.Black,
                (float)dPrintPenSize), iPrintWidth, (int)dPrintHeight, true);

        //handles the print button
        private void btnPrint_Click(object sender, EventArgs e)
            PrintDialog pDia = new PrintDialog();
            if (pDia.ShowDialog() == DialogResult.OK)
                // take printer settings from the dialog and set into the PrintDocument object
                prntDoc.PrinterSettings = pDia.PrinterSettings;
                // start the printing process, catch exceptions
                catch (Exception exc)
                    MessageBox.Show("Printing error!\n" + exc.Message, "Error", MessageBoxButtons.OK,


        //draws the barcode on a graphics object
        //arguments:  Graphics grMain -> object to draw to
        //            Pen p1          -> Pen to draw with
        //            int iWidth      -> Width of the barcode
        //            int iHeight     -> Height of the barcode
        //            bool bMode      -> True indicates textual mode
        private void BuildBarCode(Graphics grMain, Pen p1, int iWidth, int iHeight, bool bMode)
            //iterate each element of the code array and draw a line if its true
            for (int i = 0; i < 95; i++)
                if (bCode[i] == true)
                    grMain.DrawLine(p1, (iXOffset + (i * p1.Width) + (bMode == false ? 0 : (int)dPrintXOffset)),
                        (bMode == false ? 0 : (int)dPrintYOffset), iXOffset + (i * p1.Width) + (bMode == false ? 0 : (int)dPrintXOffset),
                        (bMode == false ? 0 : (int)dPrintYOffset) + iHeight);
            //this mode implies print mode, and draws my name and the barcode values
            if (bMode == true)
                grMain.DrawString(txtCode.Text + txtCheck.Text
                    new Font("Times New Roman", iWidth / 12),
                    Brushes.Black, new PointF(iXOffset + (int)dPrintXOffset, (float)iHeight + (float)dPrintYOffset));

Hope that helps.
