问题描述
我在内存中(在Java Tomcat网络应用程序中)有Postscript代码/数据(?),我想直接将其发送到联网的PS打印机。有没有一种简单的方法(即只是弹出一个端口并发送文本)来打印此内容,从而绕过所有特定于O / S的驱动程序和内容(甚至希望不需要额外的jar)?
I've got Postscript code/data (?) in memory (in a Java Tomcat webapp) that I'd like to send directly to a networked PS printer. Is there an easy way (i.e. just popping open a port and sending the text) to print this, bypassing all of the O/S-specific drivers and stuff (and hopefully not even requiring extra jars)? A link to example code showing how to do this?
谢谢,
Dave
Thanks,Dave
推荐答案
在目标打印机的LPR端口上打开一个TCP套接字。
open a TCP socket to the LPR port on the target printer.
发送数据;只要打印机理解,您就很酷。
send your data; as long as the printer comprehends it, you're cool.
完成后不要忘记换行。
(然后关闭端口。)
