1. Normalise Print Configuration (Edit Fields (Set)): sets 5 fields: baseId, jobsTable, sheetId…
2. Fetch Approved Print Jobs (HTTP Request): calls an HTTP API

4. Diff Released Revisions (Code): runs custom JavaScript code
5. Check Print Source Integrity (If): checks a condition and branches into true / false
6. Detect Revision Delta (If): checks a condition and branches into true / false
7. Stop Invalid Print Input (Code): runs custom JavaScript code
8. Debounce Artwork Changes (Wait): waits 60 seconds
9. Recheck Print Release Register (HTTP Request): calls an HTTP API
