Issues with SELFITEM-PRINTTASKDESCRBATCH

[Rick Sample]

4.6C
I have a decision task with Approve / Reject / Print. 
 
For the Print option, it calls the next Task which is a 
SELFITEM-PRINTTASKDESCRBATCH. I have Advance with Dialog checked. 
Both tasks, the decision task and print task are General Tasks with Agents 
defined by Role res. If it does not find the agent I have it set to Terminate if role 
res fails. These are in a loop.
 
Now,
In Dev the user clicks the Print option and sends correctly to the defined printer. 
It keeps the decision task on the screen like I would expect it to. i.e the user 
does not have to go back into the inbox and reopen the task for the Approve / reject. 
 
But I am experiencing issues in production. The user selects the print option and 
then it disappears from the inbox and stuck with No Administrator found. 
I am getting security to apply a role to the tasks in question, but I don't understand why 
it is working in dev and Qa but intermittently fails in prod. 
 
Any know issues or suggestions?
 
Thanks 
Rick
