          l_count      LIKE pri_params-prcop VALUE 1,
          l_list_text  LIKE pri_params-prtxt,
          l_text(12)   TYPE c.

    IF usr01-spld IS INITIAL.
      usr01-spld = 'LOCL'.
    ENDIF.
*&--GET THE EXISTING DEFAULT PARAMETERS
    CALL FUNCTION 'GET_PRINT_PARAMETERS'

Hi,
Ofcourse, its different issue...Can you explain me why you have used the below code
*&--GET THE EXISTING DEFAULT PARAMETERS
CALL FUNCTION 'GET_PRINT_PARAMETERS'
EXPORTING
no_dialog = 'X'
IMPORTING
out_parameters = l_t_params.
I mean you are importing the existing default parameters but you are not modifying the parameters in l_t_params. I hope you are not required above code.
