TSC TX600 从 android 打印？

Question

我想使用 TSC -TX600 型号（通过 USB）从 android 设备打印 Text/barcode 标签。

从 TSC 网站上，我得到了以下源代码。因此，我创建了一个新的 android 项目并添加了 libs/*.jar 文件作为依赖项。然后我在 mainActivity.java.

复制了下面的内容

当我执行此操作时，Android（代码）正在与打印机通信。（显示屏显示正在打印）但打印机没有输出任何内容。你能告诉我我在哪里搞砸了吗？我还需要发送命令详细信息（在互联网上找不到）。

PS：如果我点击打印机中的诊断选项，状态打印正确。因此，纸张或打印机没有问题。

您在此处发布的代码中似乎存在语法错误。

TscUSB.sendcommand("TEXT 100,100,\"3\",0,1,1,\"123456\"\r\n"TscUSB.sendcommand("PRINT 1\r\n");

应该是这样的：

TscUSB.sendcommand("TEXT 100,100,\"3\",0,1,1,\"123456\"\r\n"); // <-- previous command ends here
TscUSB.sendcommand("PRINT 1, 1\r\n"); // <-- Add missing argument here

更好的是，您可以简单地使用这个命令：

TscUSB.printlabel(1, 1); // <-- Ready made method on TSCUSBActivity class

此外，根据 TSPL2 编程手册，打印命令采用 2 个强制参数。（Link 这里：TSPL2 Programming Manual）
