运行时exec lp命令打印成功 [英] Runtime exec lp command print success

问题描述

我必须在java程序中打印一个PDF文件并确保它打印成功，否则抛出异常.

I have to print a PDF file in java program and make sure it's printed successfully, else throw exception.

我的代码是:

Process p = Runtime.getRuntime().exec("lp -c -n 1 -d 1.2.3.4 abc.pdf");
System.out.println(p.waitFor());

上面的代码打印0，但它只确认作业提交正常，如何确保它也被打印.

Above code prints 0, but it only confirms that job is submitted fine, how to make sure that it's printed also.

有没有其他方法可以做到这一点?

Is there any other way to do this?

推荐答案

运行 lpstat(在 lp 之后)并捕获进程输出.

Run lpstat (after lp) and capture the process output.
