如何拦截发送到打印机的数据? [英] How to intercept data being sent to a printer?

问题描述

我正在与一个应用程序交互，该应用程序将原始打印机文件发送到默认打印机.这是它对数据所做的唯一处理.

I'm interfacing with an application that's sending a raw printer file to the default printer. This is the only thing it will do with the data.

我需要以某种方式获取此文件，以便我可以将其存储在其他地方.这样做的最佳方法是什么?

I need to get this file somehow so I can store it elsewhere instead. What would be the best way to do this?

我想到的最好的方法是编写一个监听特定端口的应用程序，并将默认打印机设置为该端口.

The best I've thought of is to write an app that listens to a specific port, and set the default printer to that port.

这种方式行得通吗?有没有更好的办法?

Would this way work? Is there a better way?

推荐答案

我遇到了 Java 的 LDP 实现，我将要修改和使用它.您可以将其作为打印机访问，然后使用原始文件执行您想要的操作.

I ran across and LDP implementation for Java that I'm going to modify and use. You can access it as a printer and then do what you want with the raw files.
