Try to delete the auto created printer and check. Also if possible update Receiver for Windows 3.4 you can download the client http://support.citrix.com/article/CTX133997

Are the Citrix servers patched to the latest level, including any rollups?

Are there are any event log entries at the time of the crash?

What versions are in use?

Is it consistent across all users or specific ones? What are they doing at the time?

As Tony1044 said, you need to ensure you have the latest relevant hotfixes for XenApp 6.0.

If you did this and yet you still face the HDX crashing issue, then try disabling the client side HDX flash to see how it goes, as follows:

In the following registry key from the client side
HKCU\Software\Citrix\HdxMediaStreamForFlash\Client\PseudoContainer
disable UserEnabledFlash by changing its value to 0.

If this resolves your issue, then you need to know that the client side Flash is conflicting with the server side Flash and causing the issue. However, this should be considered as a temporary work around. I would suggest to test with the latest Citrix plugin to see whether this would resolve the Flash conflict issue.

Did you also check with a user account with admin privileges on the server? So any permission related issues can be vetted out.

Personally I feel that the OP pointed out that the resolution came in two parts: update to latest hotfixes and implement a registry key change;

Mutawadi agreed with me in his post that the latest hotfixes should be put on and did point out a registry key but it wasn't the one in the final fix.

Either the question should be closed and refunded or I should get points for pointing the OP in the right direction.

Unless the author comes back with his comments and reasons, I recommend that:
1. http:#a38799169 accepted as the solution
2. http:#a38807905 should receive a split as an assisted solution
3. http:#a38737533 should receive a split as an assisted solution

I'd agree with Mutawadi re the split.
