Batch printing in Smartforms

Question

hi guys,
i have a problem to perform batch printing and process batch printing at a button click and here is the detail explanation of the problem.
The Front End Screen will be a selection screen with (1) radio buttons listing all form letters, a field for Date of the form, (2) a field for Employee Number (PERNR), (3) a field for Request Date, (4) a field for Request Reason, (5) <b>a selection for Print Now or Print Batch</b>, and (6) <b>a Process Batch button</b>.
when Radio Button for one of the Forms selected, the User will then select the Print Now or Print Batch option. If the Print Now option was selected, the selected form will be immediately generated and printed. If the Print Batch option has been selected, the data on the Front End Screen will be stored in a batch file for processing and printing en masse.
Screen when ready to print the batch file of forms. When the Process Batch button is selected, any forms that are stored in the batch file are then processed (created and printed). Forms may be printed multiple times (one for the employee, one for the employee’s supervisor and one for the personnel file). Each form detailed below will indicate the number of copies to be printed.

Printing a Smartform is always about calling the function module generated for this form. Calling the FM is done from a printing program.
Put this program into a job using
CALL FUNCTION 'JOB_OPEN'
  EXPORTING
    jobname          = name
  IMPORTING
    jobcount         = number
  EXCEPTIONS
    cant_create_job  = 1
    invalid_job_data = 2
    jobname_missing  = 3
    OTHERS           = 4.
IF sy-subrc = 0.
" FOR each PERNR
  SUBMIT submitable TO SAP-SPOOL
                    SPOOL PARAMETERS print_parameters
                    WITHOUT SPOOL DYNPRO
                    VIA JOB name NUMBER number
                    AND RETURN.
ENDIF.
then when you want to execute the job, call this:
    CALL FUNCTION 'JOB_CLOSE'
      EXPORTING
        jobcount             = number
        jobname              = name
        strtimmed            = 'X'
      EXCEPTIONS
        cant_start_immediate = 1
        invalid_startdate    = 2
        jobname_missing      = 3
        job_close_failed     = 4
        job_nosteps          = 5
        job_notex            = 6
        lock_failed          = 7
        OTHERS               = 8.
    IF sy-subrc <> 0.
    ENDIF.
ENDIF.
