C语言 窗口中热敏打印机的自定义驱动程序

Question

我正在尝试为我的打印机开发驱动程序，该打印机正在com端口上工作。 它是最专注于收据打印的热敏打印机。但我没有任何此打印机的驱动程序，所以现在我使用 Windows"通用\仅文本打印机"drivers.it 工作，但问题是我无法控制语言.我对Windows通用文本驱动程序有一些疑问

是否可以对各种字体和语言使用泛型\纯文本模式 1.is？

2.是否有自己的语言显示器和OEM驱动程序？

3.is 可以将任何 gpd 文件与通用模式驱动程序集成

还有

基本上对于任何打印机，驱动程序中有三个主要组件，即语言监视器，OEM uni驱动程序，用户界面，该驱动程序必须在WDK中开发，对于可用于此类打印机驱动程序开发的任何开源。

任何人都对此有想法.

所以我现在回来了，我说错了 - 它不是 VB6，它已经是 C# - 你必须翻译这个（基本上你可以使用相同的 api 调用.

我还在网上的某个地方找到了这段代码......它没有从我的大脑中逃脱

这是一项服务，用于旧的DOS应用程序打印到HP Laserjet（Dos应用程序知道如何使用PCL）。

电话：

RawPrinterHelper.SendFileToPrinter(new PrinterSettings().PrinterName, fileName);

在我使用 VB6 的古老编程时代，可以将打印机作为"RAW 打印机"打开，这实际上是一种无人驾驶打印方法 - 您拥有完整的工作。

我将在我的旧资源中开始搜索这个，我很确定，如果需要，你可以将其翻译成 c 语言。
