我一直在尝试打印到SATO GL408e打印机。我试图通过USB接口发送数据但没有示例代码来执行此操作。我尝试使用此处的示例代码：http://support.microsoft.com/kb/322091但它运行时没有错误，也没有打印。有没有人知道如何将数据发送到SATO打印机？
谢谢！
（这是我正在使用的代码）

我已经解决了这个问题。 Microsoft代码运行良好。问题在于我发送给打印机的字符串。转义码无效。相反，我用命令名替换了转义码，然后用字符替换。感谢所有试图帮助的人！
这是我替换的代码：
PrintCommand = "<STX><ESC>A<ESC>IG1<ESC>Z<ETX><STX><ESC>A<ESC>#E3<ESC>Z<ETX><STX><ESC>A<ESC>CS5<ESC>Z<ETX><STX><ESC>A<ESC>EX0<ESC>Z<ETX><STX><ESC>A<ESC>*&<ESC>Z<ETX><STX><ESC>A<ESC>A3H0001V0001<ESC>Z<ETX><STX><ESC>A<ESC>V0000<ESC>H0259<ESC>F001+002<ESC>D202099" + EmployeeNo + YearNumber + FirstTraceCode + "<ESC>L0203<ESC>H0247<ESC>V0114<ESC>F001+002<ESC>U" + EmployeeNo.Substring(0, 2) + "-" + EmployeeNo.Substring(2, 4) + "-" + YearNumber + "-" + FirstTraceCode + "<ESC>V0000<ESC>H0589<ESC>F001+002<ESC>D202099" + EmployeeNo + YearNumber + SecondTraceCode + "<ESC>L0203<ESC>H0577<ESC>V0114<ESC>F001+002<ESC>U" + EmployeeNo.Substring(0, 2) + "-" + EmployeeNo.Substring(2, 4) + "-" + YearNumber + "-" + SecondTraceCode + "<ESC>Q" + LabelQuantity + "<ESC>00<ESC>Z<ETX>";
PrintCommand = PrintCommand.Replace("<STX>", ((char)02).ToString());
PrintCommand = PrintCommand.Replace("<ETX>", ((char)03).ToString());
PrintCommand = PrintCommand.Replace("<ESC>", ((char)27).ToString());
