Sending output to a printer in a background job

I did a quick search on this issue and found a few suggestions. One suggestion was to use something like this:

SUBMIT RSFLFIND ... TO SAP-SPOOL DESTINATION 'LT50'.

I looked at the SAP help for SUBMIT and it was quite helpful however it raised a few questions. The program that am writing will be run in the background. I want to create a simple report that will print at several different printers when it is done. Looking at the help section (specifically this part):

"The SUBMIT statement accesses an executable program rep. The executable program is executed as described under Calling Executable Reports.

The program name rep can either be specified directly or as the content of a character-like data object name. The data object name must contain the name of the program to be accessed in block capitals. If the program specified in name is not found, an irretrievable exception is generated.

The selscreen_options additions can be used to determine the selection screen for the program accessed and to supply it with values.

The list_options additions allow you to influence the output medium and the page size in the basic list for the program accessed.

You can schedule the program for background processing by specifying job_options. "

It seems like I would create a simple program like this:

DATA: number TYPE tbtcjob-jobcount, 
      name TYPE tbtcjob-jobname VALUE 'JOB_TEST', 
      print_parameters TYPE pri_params. 

... 

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. 
  SUBMIT submitable TO SAP-SPOOL 
                    SPOOL DESTINATION 'LT50'.
                    VIA JOB name NUMBER number 
                    AND RETURN. 
  IF sy-subrc = 0. 
    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. 
ENDIF. 

That will then call the background job and the output will go to the print spool. I have a few reservations about this. The print spool will not be determined until the background job. The background job creates sales orders and the material group, in the sales order, determines the printer that the final report will go to. Also, if this is the way to do it, do I just do simple write statements in the background job?
