Hi Urkec,

It works well! Before I printign, now I can know the state of the printer.
Now, Could you tell me What is WMI and How can we take advantage of it?


WMI stands for Windows Management Instrumentation. It is used mostly for
system administration (getting system information, monitoring etc). It is a
set of classes (like Win32_Printer) that represent just about any computer
component you can think of. It can be very useful.

Hope this helps. I'm sure you can google a much better answer.
