How to print in a web dynpro application

Hello everybody,

i´ve got a problem with one of our web dynpro applications.

In our application users have to print some lists. We do this by calling a Fuba:

*"----------------------------------------------------------------------
*"*"Lokale Schnittstelle:
*"  IMPORTING
*"     VALUE(P_BEST) TYPE  CHAR20 OPTIONAL
*"     VALUE(P_MATNR) TYPE  MATNR OPTIONAL

*"     VALUE(P_LGORT) TYPE  LGORT_D OPTIONAL
*"     VALUE(P_MENG1) TYPE  CHAR15 OPTIONAL

      print_parameters TYPE pri_params,
      valid type string.
      print_parameters-PRIMM = '1'.

CALL FUNCTION 'GET_PRINT_PARAMETERS'       "Beschaffen von

  IMPORTING OUT_PARAMETERS        = print_parameters.

                    SPOOL PARAMETERS print_parameters
                     WITHOUT Spool DYNPRO
                    AND RETURN
                    with p_lief  = p_lief "Lieferantenname
                    with p_wedat = SY-datum
                    with p_best  = p_best
                    with p_matnr = p_matnr
                    with p_maktx = p_maktx
                    with p_lgort = p_lgpla
                    with p_meng1 = p_meng1
                    with p_ean   = p_ean
                    with p_agp   = p_agp
                    with p_mhd   = p_mhd
                    with p_charg = p_charg
                    with p_brgew = p_brgew.


ENDFUNCTION.

This Fuba calls a report "ZETIKETT_WE_Z_BEST" which should be printed immediatelly on the local printer of the user.

So far it´s ok. The fuba get called, the rebot is made and a spool job is created.

But...

The spool job doesn´t print. In "my spool jobs" it´s marked as "done".

Now another strange thing. If we debugg the appliacation (don´t change anything only pressing F5) the SAPLPD is called an the report is printed perfekt. Can someone help me?

Points guaranteed....
