自定义驱动程序用于Windows中的热敏打印

Question

我正在尝试为我的打印机开发驱动程序，该驱动程序正在使用com端口。它是一台热敏打印机，主要关注收据打印。但是我没有这台打印机的任何驱动程序，所以现在我使用Windows“GENERIC \ TEXT ONLY PRINTER” 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

1.是否可以对各种字体和语言使用通用\纯文本模式？

2.它是否拥有自己的语言监控器和OEM驱动程序？

3.是否可以将任何gpd文件与通用模式驱动程序

集成

以及

基本上，对于任何打印机，驱动程序中有三个主要组件是语言监视器，OEM单驱动程序，用户界面，该驱动程序必须在WDK中开发，用于任何可用于打印机驱动程序开发的开源。

任何人都有这个想法。

所以我现在回来了，我说错了 - 它不是VB6，它已经是C＃ - 你将不得不翻译它（基本上你可以使用相同的api调用..）

我还在网络的某个地方找到了这个代码...它没有逃脱我的大脑

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）。

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

在我使用VB6的古老编程时代，可以将打印机打开为“RAW打印机”，这实际上是一种无人驾驶打印方法 - 您可以完成所有工作。

我会在我的旧资源中开始搜索，我很确定，如果需要，可以将其翻译成c语言。
