C#通過條碼印表機列印條碼(斑馬印表機)

很久登陸部落格園了,自己剛進入開發這行一年,部落格上一直不知道寫什麼,現在把自己工作中遇到的一些關於使用條碼印表機的一些代碼,貼出來,希望能給出學者帶來點協助,本人水平有限,寫的不好多多包含,具體代碼如下:

//此類作用開啟印表機的串口

 internal class BarcodePrinter
    {

//連接埠
        private string fileName;

        public BarcodePrinter(string port)
        {
            this.fileName = port;
        }

        [DllImport("PrinteDll.dll")]
        private static extern int ClosePrinter();

//取得列印命令
        public string GetLabelCommand(string fileName)
        {
            StreamReader reader = new StreamReader(fileName);
            string str = "";
            string str2 = null;
            while ((str2 = reader.ReadLine()) != null)
            {
                str = str + str2;
            }
            reader.Close();
            return str;
        }

        [DllImport("PrinteDll.dll")]
        private static extern int OpenPrinter(string fileName);

//列印條碼
        public void PrintLabel(string text)
        {
            if (OpenPrinter(this.fileName) < 0)
            {
                throw new Exception("標籤列印：開啟 " + this.fileName + " 失敗。");
            }
            Write(text);
            ClosePrinter();
        }

        [DllImport("PrinteDll.dll")]
        private static extern int Write(string text);
    }

 

 

//調用

//執行個體化列印對象

BarcodePrinter v_barcode_printer = new Pack_BarCode.Model.BarcodePrinter(串口);

//ZPL II語言(具體參考ZPL II說明)

string strPrint="^XA
^LH0,0
^FO60,303^GB1100,0,10^FS
^FO550,303^GB0,647,10^FS
^FO120,670^A0,25,40^FDPN:$P^FS
^XZ";

//列印方法.

private void PrintText(string str)

{

     v_barcode_printer ..PrintLabel(strPrint.Replace("$P",str);

}
