Send the Webdynpro Output screen to Spool

Dear All,

I have a requirement to Print the output screen of the Webdynpro application.

Scenario,

I have a ALV table as an output in the webdynpro application, and there i have given a Print button to print that table.

the ONACTION_PRINT code is

"data lo_comp type REF TO if_wd_component.
   data lo_appl TYPE REF TO if_wd_application.

   lo_comp = wd_comp_controller->wd_get_api( ).
   lo_appl = lo_comp->get_application( ).

   lo_appl->print_page( )."

The output table shows about  16 columns and once we give print it prints only 9 or 10 columns, the remaining i am unable to print, is there any provision to

Print the entire table.

OR

How to send this webdynpro application screen to spool,

Please let me know you thoughts

Regards,

Balaji sha
