PosPrinter.PrintBarCode，PosPrinter.PrintBitmap在PrintNormal工作時不工作

我創建了一個ActiveX控件，其中包含處理打印機（Star TSP100）的所有方法，如實例化，打印機等。ActiveX正在註冊com。當我通過javascript使用打印機方法時，除PrintBarCode和PrintBitmap方法外，所有方法都正常工作，並引發錯誤。PosPrinter.PrintBarCode，PosPrinter.PrintBitmap在PrintNormal工作時不工作

位圖我用： -

printer.PrintBitmap(PrinterStation.Receipt, path, percentWidth * lineWidth/100, PosPrinter.PrinterBitmapCenter);

和條碼： -

printer.PrintBarCode(PrinterStation.Receipt, code, BarCodeSymbology.Code93, 80, (int)(0.9 * lineWidth), PosPrinter.PrinterBarCodeCenter, BarCodeTextPosition.Below);

雖然這兩種方法也在從Visual Studio調試模式下工作。但是在系統中創建安裝並安裝後，這兩者不起作用。

的錯誤是： -

Microsoft.PointOfService.PosControlException: Method PrintBarCode threw an exception. Attempt was made to perform an illegal or unsupported operation with the device, or an invalid parameter value was used.

我有同樣的問題，併爲位圖我有一個解決辦法：

printer.PrintBitmap(PrinterStation.Receipt, path, PosPrinter.PrinterBitmapAsIs, PosPrinter.PrinterBitmapCenter);

也許打印機不能夠擴展位圖。但是，在將位圖發送到打印機之前，很容易縮放位圖，我認爲這是一個很好的解決方法。

對於條碼問題，我只能說，我有錯誤的BarCodeSymbology（Ean13S而不是EanJan13）。如果我有進一步的見解，我會在這裏分享。

DLG：是打開文件對話框

cbAlignment：是包含三個值組合框：左，中，右。

tbWidth和tbWidth：用於印刷

cbTextPosition的大小：對於文本位置

這裏是一個屏幕截圖：

enter image description here

我有Epson-T20，代碼工作正常，我：

//In the loading of the form : to init cbTextPosition 
cbTextPosition.Items.Clear(); 
cbTextPosition.Items.AddRange(Enum.GetNames(typeof (BarCodeTextPosition)));

並打印：

try 
      { 
       //Show the Open File Dialog Box 
       OpenFileDialog dlg = new OpenFileDialog(); 
       dlg.Filter = "Image files|*.bmp;*.gif;*.jpg"; 

       //Try It First With Monochrome Bmp Image : try it with 384x384 px 
       if (dlg.ShowDialog() == DialogResult.OK) 
       { 
        //Init your stuff here 
        PosExplorer explorer; 
        DeviceInfo _device; 
        PosPrinter _oposPrinter; 

        explorer = new PosExplorer(); 
        _device = explorer.GetDevice(DeviceType.PosPrinter, "T20PRINTER"); 

        _oposPrinter = (PosPrinter) explorer.CreateInstance(_device); 
        _oposPrinter.Open(); 
        if (!_oposPrinter.Claimed) 
        { 
         _oposPrinter.Claim(5000); 
         _oposPrinter.DeviceEnabled = true; 
         PrinterStation CurrentStation = PrinterStation.Receipt; 

         //This is a Header : 
         _oposPrinter.PrintNormal(PrinterStation.Receipt, "Here is your LOGO : "); 

         //Printing Your Logo : 
         int alignment; 
         if (cbAlignment.Text == "Left") 
          alignment = PosPrinter.PrinterBarCodeLeft; 
         else if (cbAlignment.Text == "Center") 
          alignment = PosPrinter.PrinterBarCodeCenter; 
         else if (cbAlignment.Text == "Right") 
          alignment = PosPrinter.PrinterBarCodeRight; 
         else 
          alignment = int.Parse(cbAlignment.Text, System.Globalization.CultureInfo.CurrentCulture); 

         //Print it : you can try 384px for real size in tbWidth 
         _oposPrinter.PrintBitmap(
          CurrentStation, 
          dlg.FileName, 
          int.Parse(tbWidth.Text, System.Globalization.CultureInfo.CurrentCulture), 
          alignment); 

         //Cutting your Paper : 
         _oposPrinter.CutPaper(95); 
        } 

       } 

      } 
      catch (Exception c) 
      { 
       MessageBox.Show(c.Message); 
      }

對於條形碼數據從來沒有嘗試過對不起，如果我找到的東西，我會告訴你，好運氣的傢伙。
