 public  class TSCLIB_DLL
    {
        [DllImport("TSCLIB.dll", EntryPoint = "about")]
        public static extern int about();

        [DllImport("TSCLIB.dll", EntryPoint = "openport")]
        public static extern int openport(string printername);

        [DllImport("TSCLIB.dll", EntryPoint = "printerfont")]
        public static extern int printerfont(string x, string y, string fonttype,
                           string rotation, string xmul, string ymul,
                           string text);

    }

文本打印正常：

SCLIB_DLL.windowsfont(280, 118, 24, 0, 2, 0, "宋体", "产品颜色");

二维码 图片打印不正常 无法打印出来也没有图片

图片打印

 TSCLIB_DLL.downloadpcx("1.BMP ", " TS1C.BMP ");
 TSCLIB_DLL.sendcommand("PUTBMP 100,100, \" TS1C.BMP \"");

二维码打印

 TSCLIB_DLL.sendcommand("QRCODE 50,50,H,4,A,0,M2,S7,\"123TSCtest\"");

完整代码：

    TSCLIB_DLL.openport("TSC TTP-243E");
    TSCLIB_DLL.setup("70", "50", "4", "8", "0", "3.5", "0");
    TSCLIB_DLL.clearbuffer();

   TSCLIB_DLL.windowsfont(280, 70, 24, 0, 2, 0, "宋体", "ASDFAA");
   TSCLIB_DLL.downloadpcx("1.BMP ", " TS1C.BMP ");
   TSCLIB_DLL.sendcommand("PUTBMP 100,100, \" TS1C.BMP \"");

   TSCLIB_DLL.sendcommand("QRCODE 50,50,H,4,A,0,M2,S7,\"123TSCtest\"");

   TSCLIB_DLL.printlabel("1", "1");
   TSCLIB_DLL.closeport();

现在的问题是，除了能打印文本，其他的都不能打印，直接复制官方的文档也不行，我使用的语言是c#。

我是少配置了什么？还是少了什么打印参数？是打印机不支持？

不报错，也打印不出来
