I'm writing a Java screen-scraping application for a 3270 mainframe and rather than scroll through page after page of 80x24 chars I'd like to output all pages to a printer and then capture and parse the printer output.
我正在为3270主机编写一个Java屏幕抓取应用程序,而不是逐页滚动浏览80x24字符的页面我想将所有页面输出到打印机,然后捕获并解析打印机输出。
The 3270 client has a print option, so I just need to virtualise a printer device and then somehow capture the output. Has anyone achieved this in Linux before?
3270客户端有一个打印选项,所以我只需要虚拟化打印机设备,然后以某种方式捕获输出。有没有人在Linux之前实现这一点?

You probably want to create a lpd-queue for this purpose and then hook into that.
您可能希望为此目的创建一个lpd队列,然后挂钩。

If this is 3270 via VT100 you can issue VT100 print capture commands at the terminal. Otherwise, as already answered you can enable LPD and put a filter on it to tee it to a file.
如果这是通过VT100的3270,您可以在终端发出VT100打印捕获命令。否则,正如已经回答的那样,您可以启用LPD并在其上放置一个过滤器以将其发送到文件。
