From an integration the Print Scheduler handles the print task, as described in this article: https://support.seagullscientific.com/hc/en-us/articles/1500001384742-Troubleshooting-Guide-Integrations
Is is possible to log the exact received XML for every Print Scheduler Task?

Maybe by altering the n-log configuration?

Or adding an extra line in the Integration task.
Or by starting the scheduler with a command line option?
