Hi Jack,
thank you for your post.
Please note the hints in our online knowledgebase:
Make sure to open a job/create a component instance in your application before starting the first print thread and do not close this job before all threads are terminated. Typically, this will be done in your application’s start-up and shutdown code. Background: the first job creates a couple of helper objects that need to be destroyed in the same job. Also, this can increase the performance remarkably as it avoids steady loading and unloading of DLLs.
If this will not solve the problem, then we will need additional information that cannot be exchanged through the forum platform.I’d suggest to open a support case via our support portal. Please copy any pertinent information from this thread into the case description.
Best regards,
Christian Rauchfuß
