Can you please clarify?
In your nsq that you created in designer, you have a report assigned to a task, the task is assigned to a job, the job assigned to a schedule. All of that is saved in the nsq. From the server console, you point to the nsq to be processed.
At what point does the error occur?when the service tries to run the task,when pointing to the nsq?
Is the user runnign the nprinting service the same or differnt the the user running the qlikview services - they should be different
