Adobe Reader 11.0 (AcroRd32) does not close

Hi,

I am using CL_GUI_FRONTEND_SERVICES=>Execute method to print PDF form in foreground passing '/t' as parameter. Once executed the Adobe Reader opens and then the file opens and close and go to printer but the Adobe Reader remains open and does not close.

Is there any way I can close the reader too along with the document?

Thanks for the help.

Regards,
