Query Latest Pending Print Task
A third-party platform calls the Query Latest Pending Print Task interface (/api/Printer/getLastTask) to query the open platform for details of the latest pending / in-progress task on a designated printer. The platform returns synchronously the task ID, order number, print status, product information, image URL, timestamps, and the merged-print flag — used for front-end status display or business-logic decisions.
