We have a Citrix XenApp 6.5 farm on Windows 2008 R2 that serves an application to our end users. Recently we have found that if the spooler service hangs, the application no longer launches for new users that login because the application queries the spooler service on startup. Users print using this application on a daily basis.
I believe there is an issue with printer drivers that is causing the spooler service to hang, but we are unable to reproduce the issue reliably.
If I do have a bad printer driver, how can I isolated and identify it? If it is not a printer driver how can I identify what is causing the spooler to hang?
Any help is appreciated. Thanks.

Another possibility to create a crash or hang dumb with the
Debug Diagnostic Tool https://www.microsoft.com/en-us/download/details.aspx?id=49924
Select what you what to monitor, in this case the spooler service and let it create a full hand or crash dumb.
You should be able to find the driver/dll that causes the issues and then, as mentioned before, isolate tis driver or better try to find a replacement that you can you.
