ABAP - PDF file font size too small

Hi,

We are using function module - CONVERT_ABAPSPOOLJOB_2_PDF  to generate a PDF file . The PDF file generated has very small font size. Could someone please provide a step by step approach to deal with this problem .

I searched existing posts in SCN and got this piece of code which changes printer parameter :

CALL FUNCTION 'RSPO_R_SELECT_TSP01'
     EXPORTING
       rqident   = gv_spool_nr
     TABLES
       tsp01desc = gt_spool
     EXCEPTIONS
       error     = 1
       OTHERS    = 2.
   IF sy-subrc = 0.
*Passing RQPAPER has the key and getting the paper format.
     READ TABLE gt_spool INTO gs_spool WITH KEY param = 'RQPAPER'.
     IF sy-subrc = 0.
*          CASE gv_flag.
*            WHEN 'X'.
*              gs_spool-value = '200'.
*            WHEN 'L'.
*              gs_spool-value = '512'.
*            WHEN OTHERS.
               gs_spool-value = 'X_65_200'.
*          ENDCASE.
       MODIFY gt_spool INDEX 21 FROM gs_spool.
     ENDIF.
   ENDIF.

   CALL FUNCTION 'RSPO_R_UPDATE_TSP01'
     TABLES
       tsp01desc = gt_spool.
   COMMIT WORK.

Unfortunately , I could not find a suitable format that could adjust all my columns in one page with proper font size. Could some one please throw some insight into this problem solution ?
