我正在编写C应用程序,需要使用rawprinterhelper将数据打印到pos star打印机。

我的印刷效果很好,除了我发送像_½___这样的字符。 然后我得到错误的数据打印出来。

到目前为止,我的研究给了我以下的结果。

如果我在PowerShell中打开良好的旧编辑并在TXT文件中写入我的字符(_½_) 把它送到打印机,我就可以随心所欲地打印出来。

我不能重复使用记事本

我如何用C编码我的刺,使其看起来像来自命令提示符(eidtor)的刺。所以 当我将数据发送到打印机时,它会像在Windows环境中那样打印所需的字体。

我还尝试使用Star驱动程序和他们的C样本进行打印,以便将数据直接发送到打印机,但没有成功。

编辑:

我做到了,对于其他人来说,他们通常很难用C直接在星型打印机上打印。# 这是示例应用程序的代码 Star IO Programming Tool 使用他们的司机。
