挂件打印错误 [英] Catch printing error

问题描述

我直接打印而不打开打印对话框.
一切正常，但问题是在打印时是否有任何错误，我无法捕捉到该错误.

我已经尝试过Window.onbeforeerror和onaftererror

并尝试捕获

但没有用....

请在此帮助我

我确定有解决此问题的方法，或者有一个变量告诉我无法打印

在此先感谢

Hi ,

I am giving a direct print without opening a print dialog box.
Every thing is working fine,but the thing is if there is any error while printing I am not able to catch the error.

I have tried Window.onbeforeerror and onaftererror

and try catch

but of no use....

kindly help me in this

I am sure there is some solution for this problem or a variable which tells me unable to print

Thanks in advance
varun

推荐答案

我们可以做的一件事是，
我们可以拥有一个日志文件，并且可以在代码中捕获异常消息并将其写入日志文件.

One thing what we can do for it is,
we can have a log file and we can catch the exception message in the code and write it into log file.
