Why the control parameters changed when print smart form

Question

Hi experts:
  I set the control parrameters in my source code to print the smart form, I use the loop table for printing, but I found the print device changed automatically, only the frist page is ok. that means, the control paramenters lost when loop. how to solve it?
this is my source:
LOOP AT it_outtab INTO wa_outtab WHERE flag = 'X' .
    ssf_open ls_control_param outopt ls_composer_param.
    CALL FUNCTION 'SSF_FUNCTION_MODULE_NAME'
      EXPORTING
        formname           = lf_formname
      IMPORTING
        fm_name            = lf_fm_name
      EXCEPTIONS
        no_form            = 1
        no_function_module = 2
        OTHERS             = 3.
   IF sy-subrc <> 0.
     MESSAGE 'Call SSF_FUNCTION_MODULE_NAME Error' TYPE 'E'.
   ENDIF.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
              WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
    CALL FUNCTION lf_fm_name
      EXPORTING
        control_parameters = ls_control_param
        zgl_k_stru         = wa_outtab
      EXCEPTIONS
        formatting_error   = 1
        internal_error     = 2
        send_error         = 3
        user_canceled      = 4
        OTHERS             = 5.
   IF sy-subrc <> 0.
     MESSAGE 'Call LF_FM_NAME Error' TYPE 'E'.
   ENDIF.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
              WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
    ssf_close .
    MOVE-CORRESPONDING outopt TO ls_composer_param.
    ls_composer_param-tdimmed = ' '.
    ls_control_param-no_dialog = 'X'.
    IF outopt-tdpreview = 'X'.
      EXIT.
    ENDIF.
  ENDLOOP.

Hi Prabhat,
Please check following point in your smartform design.
1) In your smartform design, how many pages do you have? (Check the page format and margins, have a look at form painter
    as well)
2) Check out the navigation from one page to another page.
3) Debugg the form and check at what point the last page is been added.
Regards,
Amee.
