srw.run_product does not create report output in pdf file on Client

Hello Experts,

We are using Report Builder 11.1.2.2.0 with Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production on Windows Machine,

We have installed Oracle Weblogic.

We used following coding to generate the report output on local machine but it opens the report in browser.

We had tried to call the coding on After Parameter Form Trigger and on Before Report Trigger, but no success.

function BeforeReport return boolean is
  cmdline varchar2(4000);
begin
   IF :print_mode <> 'PRINT' THEN
      :DESTYPE   := 'LOCALFILE';
      :PRINTJOB  := 'NO';
      :DESFORMAT := :print_mode;
      :DESNAME   := 'C:\TEMP\FAXP.'||SUBSTR(:print_mode, 1, 3);
    cmdline := 'BATCH=YES';
   cmdline := cmdline || ' DESTYPE=LOCALFILE';
