C#客户端打印条形码

第一种方法：

引用第三方插件文件zxing.dll

 // 1.设置条形码规格
             EncodingOptions encodeOption = new EncodingOptions();
             encodeOption.Height = ; // 必须制定高度、宽度
             encodeOption.Width = ;
             encodeOption.Margin = ;
             encodeOption.PureBarcode = true;

             // 2.生成条形码图片并保存
             ZXing.BarcodeWriter wr = new BarcodeWriter();
             wr.Options = encodeOption;
             wr.Format = BarcodeFormat.CODE_128;  // 这里可以设定条码的标准
             Bitmap img = wr.Write(""); // 生成图片
             string filePath = System.AppDomain.CurrentDomain.BaseDirectory + "..\\CODE_131.jpg";
             img.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);

第二种方法：

引用第三方插件库文件BarcodeLib.dll和BarCode.dll文件

  //竖型条形码
            BarcodeLib.Barcode barcode = new BarcodeLib.Barcode();
            barcode.Alignment = BarcodeLib.AlignmentPositions.CENTER;
            barcode.Width = ;
            barcode.Height = ;
            barcode.RotateFlipType = RotateFlipType.Rotate90FlipNone;
            barcode.BackColor = Color.White;
            barcode.ForeColor = Color.Black;
            string filePath = System.AppDomain.CurrentDomain.BaseDirectory + "..\\CODE.jpg";
            Image img = barcode.Encode(BarcodeLib.TYPE.CODE128, "");
            img.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);

             //条形码
            BarcodeLib.Barcode barcode_2 = new BarcodeLib.Barcode();
            barcode_2.Alignment = BarcodeLib.AlignmentPositions.CENTER;
            barcode_2.Width = ;
            barcode_2.Height = ;
            barcode_2.RotateFlipType = RotateFlipType.RotateNoneFlipNone;
            barcode_2.BackColor = Color.White;
            barcode_2.ForeColor = Color.Black;
            string filePath_2 = System.AppDomain.CurrentDomain.BaseDirectory + "..\\CODE_2.jpg";
            Image img_2 = barcode_2.Encode(BarcodeLib.TYPE.CODE128, "");
            img_2.Save(filePath_2, System.Drawing.Imaging.ImageFormat.Jpeg);
