Printer setup when SMARTFORM is printing

Hello guys.

I have a problem with smartform printing, when I make it, there is screen with printing input parameters like OutputDevice, Copies, Page selection, Print immediatelly etc. All of this parameters are stored in SSFCOMPOP structure, but there is no information about Frontend printer...

Frontend printer option I can confugure by RSPO_FRONTEND_PRINTERS_FOR_DEV fm, but there is a problem, how can I "send" it to smartform?

Thanks in advance.

Daniel
