Hi Elizabeth,
Use CO04N for mass printing of production orders.
Also, please refer OSS note 11104.You can also use an additional report (PPPRBSEL), which, like
Transactions CO04 and CO04N, selects the orders to be printed then prints them. You can also schedule a job for this report.
Print Production Orders (in Mass Processing) - Production Orders (PP-SFC) - SAP Library
Thanks & Regards,
