How to print the smartforms to the windows local printer from WD4A

Hi Experts,

How to print the Smartforms to the windows local printer (LOCL) from Webdynpro for ABAP, where the application runs within SAPGUI.

I created a T-code for the application which runs within SAPGUI. And why its not finding the windows local printer in webdynpro application, where it does prints in SE38 custom program.

And this application does not require to show the pdf preview, as it is created in ZPL code especially for Zebra Printer.

Your help is highly appreciated.

Thanks,

Raj
