Copying print program for sapscript

Hello all,

I would like to customize the print program PSFCPICK which we are using to print a sap script for shop orders.

So I did a copy of the program and named the new one ZPSFCPICK and assigned the copied print program to the list in OPK8. I know the copied print program is called when printing the script,

but no output is coming out of the printer. When I change it back to the original program, it is working fine.

Is there anything I have to pay attention when copying a print program??

Thanks

Anne
