Hi Rayan ,
As already explained by other experts we can attach the smart form with ref to plant & order type combination in t-code -OPK8 & we can also set the criteria of printing .
I believe we don't have any other setting which needs to be done from PP side . Please consult with you ABAP team probably they need to design the smartform in T-code - SE73 for Bar code .
Thanks,
Regards,
Aman
