Converting a Smartform to ZPL format

Hi,

i'm facing the following Problem: i need to convert a smartform into zpl format.

I don't need to print the smartform on a ZPL printer by using SAP standard procedure, i need the Smartform in ZPL as a "string" to send it by RFC to a specified destination (where the ZPL will be printed, finally).

Thanks for your support,

greeting Hannes
