Printing Report - Urgent please

Question

Hi All,
Can anyone please help me with the following printing problem.
I created a report using class cl_gui_list_tree. The report looks like our windows directory stucture. Like directory/sub-directory/file. This is NOT sapscript.
The above class does not have any print methods. I used the following code to print it. It shows the print parameter screen where we can select the printer/format etc. Once press the green check mark, it will not do anything.
The code:
case ok_code.
  when 'PRIN'.
  data: l_status type c.
  call function 'PRINT_REPORT'
    exporting
     NO_DIALOG                    = ' '
      report                       = sy-repid
   IMPORTING
     STATUS                       = l_status
   EXCEPTIONS
     ARCHIVE_INFO_NOT_FOUND       = 1
     OTHERS                       = 2
  if sy-subrc <> 0.
  endif.
First question is: Can I use the above function module for printing?
If this is not the right one please let me know the right function module.
If we can use above function module whatelse I have to do to get it printed?
Thanks in advance.

I am not sure for the function module but here is a suggestion - write data to spool, get the spool request no.
And then use fm RSPO_OUTPUT_SPOOL_REQUEST to print spool request.
You can try this approach. Let me know if you need any help to create Spool request.
