Print with write statements from webynpro does not trigger top-of-page

Question

Print launched from webdynpro application via application server created with write statements does not trigger top-of-page event. When print is done from sapgui it works ok. The idea is to reuse backend print which was created for sapgui with abap list made application log in webdynpro application.

Hi,
here a short extract like i do it:
CLASS LCL_EVENT_HANDLER DEFINITION .
  PUBLIC SECTION .
    METHODS:
   HANDLE_PRINT_TOP_OF_PAGE
         FOR EVENT PRINT_TOP_OF_PAGE OF CL_GUI_ALV_GRID,
ENDCLASS.                    "LCL_EVENT_HANDLER DEFINITION
* Event-Händer Implementierung
CLASS LCL_EVENT_HANDLER IMPLEMENTATION .
  METHOD HANDLE_PRINT_TOP_OF_PAGE.
      PERFORM PRINT_TOP_OF_PAGE.
  ENDMETHOD.   
ENDCLASS.
  CREATE OBJECT GR_EVENT_HANDLER.
  SET HANDLER
  GR_EVENT_HANDLER->HANDLE_PRINT_TOP_OF_PAGE  FOR GR_ALVGRID_LEFT.
  CALL METHOD GR_ALVGRID_LEFT->SET_TABLE_FOR_FIRST_DISPLAY
FORM PRINT_TOP_OF_PAGE.
  LINSZ = SY-LINSZ - 16.
  WRITE: / 'Report:   ', SY-REPID,
           AT LINSZ 'Datum:',  SY-DATUM.
  WRITE: / 'Benutzer: ', SY-UNAME,
           AT LINSZ 'Zeit: ', SY-UZEIT.
ENDFORM.
hope it helps.
