Printer set up to make PO status incorrectly processed

Hi All,

We are using SRM 7, Extended Classic Sceanrio, ECC6

We had the requirement from business to set up the printer at purchasing organization level such that if the PO output is print and no email is maintained in vendor master then PO should go to incorrectly processed (status under header tab) and should not print the PO output, so that purchaser will get the list PO which are incorrectly processed and make furhter actions. Currently it is being printed in users local printer and PO is going to correctly processed status and going to succesfully processed status.

So we tried to lock printer in SPAD set up, but POs are still going to succesfully processed status.

Please guid me, how to set up printer to achieve above requirement.

Thank you in Advance
