如何将ESC控件发送到Microsoft.PointOfService仿真程序

Question

以下是Micrsoft.PointOfService打印机的ESC码：

  string escAlignCenter = String.Format("{0}|cA", ((char)27));
  string escAlignRight = String.Format("{0}|rA", ((char)27));
  string escBoldOn = String.Format("{0}|bC", ((char)27));
  string escNewLine = String.Format("{0}|1lF", ((char)27));
  string escPaperCut = String.Format("{0}{1}|P", ((char)27), AppSettings.POSPrinterLinesToCut);
  string escReset = String.Format("{0}|N", ((char)27));
  string escUnderlineOn = String.Format("{0}|uC", ((char)27));

这段代码

simulatedReceipt.AppendLine(string.Format("{0}{1}Header will appear Here{2}",  escBoldOn, escAlignCenter, escReset));

当发送到模拟器打印机时

 textToPrint = simulatedReceipt.ToString();
 posPrinter.PrintNormal(PrinterStation.Receipt, textToPrint);

结果如下：

  System.FormatException occurred
  HResult=-2146233033
  Message=Input string was not in a correct format.

  InnerException: 

不幸的是，我没有合适的收据打印机来测试它，但我怀疑只有内置的热敏打印机模拟器才会出现错误。

有人能证实我的怀疑吗。

检查SDK示例后，很明显，在发送到模拟器之前删除了控制代码，因此模拟器似乎不会模拟粗体等。
