从打印机端口捕获数据并保存到文件（Excel / PDF） [英] Capture data from printer port and save to file (Excel/PDF)

问题描述

我有一个大型机应用程序，通过它我们可以发送文件打印命令。由于此应用程序是基于LAN的，并且它直接连接到LAN上的打印机，即使我将默认打印机更改为'PDFCreater'，打印命令也会转到LAN上的打印机。 我想创建一个应用程序，通过该应用程序，我可以从打印机端口读取数据，并根据需要将其保存为软拷贝（pdf或excel）。

任何人都可以帮我这个吗？



谢谢&问候，

Harshala

Hi,

I have one mainframe application through which we can send command for document printing. As this application is LAN based and it directly connected to printer on LAN, even though i changed default printer as 'PDFCreater' print command goes to printer on LAN. I want to create one application through which i can read data from printer port and save it into soft copy (pdf or excel) as required.
can anyone help me with this??

Thanks & Regards,
Harshala

推荐答案

很久以后有人问过一个技巧问题... + 5 for that :)



我不知道我是否知道答案，但这是我的第一件事......



根据此 [ ^ ]，大型机的打印机端口 515 ，所以尝试使用以下文章 C＃中的网络嗅探器 [ ^ ]，如果要从端口解析数据，则< a href =http://www.faqs.org/rfcs/rfc1179.html>这里是协议说明 [ ^ ]



祝你好运......

Well after a long time someone asked a trick question... +5 for that :)

I don't know whether I know the answer or not, but this is the first thing comes my mind...

according to this [^], the printer port for mainframe is 515, so try to capture the data from that port using following article A Network Sniffer in C#[^], if you want to parse the data from the port, then here is the protocol description[^]

Good luck...
