Get notification from command line or other application when a printer finish printng?

Question

Hello! I am working on a game in which people take selfie via webcam and the photo is printed by a printer.

I am using System.Diagnostics.Process to open cmd.exe and pass command into it.

("rundll32 C:\\WINDOWS\\system32\\shimgvw.dll,ImageView_PrintTo " + "\"" + (Path) + "\"" + " " + "\"" + "(Printer Name)" + "\"")

This works and my printer successfully prints photo. However I also want Unity can be able to check whether the printing is done.

After searching and trying I know I can use Prnjobs.vbs or Prncnfg.vbs to know status of printing jobs in command line. ![alt text][1] But I don't konw how to let Unity know the printing status.

Maybe there is some way to save those information as a text file from cmd, and then ask Unity to read it? Or make another small WPF or Windows Form application to check the status (maybe the Win32_Printer class is what I need?) and make it talk to Unity?

I will be really grateful if you can give me some advice. Thank you!

This may do the trick! Run prnjobs.vbs in CMD and use StandardOutput.ReadToEnd() to read the output from CMD

I've implemented this and put it on github.
