Print Page Functionality

Question

Hi all,
I'm somewhat new to CRM 7.0, coming from years of Enterprise Portal Java and R/3 ABAP development (add to that experience in CRM 5.0 E-Commerce Java and ABAP).
I have a (CRM 7.0) query about the system button 'Print' (icon) that appears on the top right of the work area.
On most pages it's there. When I'm creating a Lead it's there. From lead creation (component BT108H_LEA) I'm able to move to the 'New Assignment' creation page (component ICCMP_SURVEY) and the print functionality is no longer there. I was asked to correct that.
Now, being a developer, I generally look for a coded solution; and I came up with one... it's done. However, I also understand that customizing solutions are generally preferable to coding. My solution was to redefine IF_BSP_WD_TOOLBAR_CALLBACK~GET_SYSTEM_BUTTONS and add this code:
METHOD if_bsp_wd_toolbar_callback~get_system_buttons.
  DATA: ls_button TYPE crmt_thtmlb_button_ext.
  CALL METHOD super->if_bsp_wd_toolbar_callback~get_system_buttons
    RECEIVING
      rt_buttons = rt_buttons.
* PRINT BUTTON
    CLEAR ls_button.
    ls_button-page_id         = me->component_id.
    ls_button-type            = cl_thtmlb_util=>gc_icon_print.
    ls_button-enabled         = 'X'.
    ls_button-on_client_click = `crmFrwPrint();`.           "#EC NOTEXT
    ls_button-tooltip         =  text-000.
    APPEND ls_button TO rt_buttons.
ENDMETHOD.
So it works... but still, I'd much rather know what it is that tells one page to return the Print button from ~get_system_buttons and what tells another page not to.
Where is that defined? Is it in customizing? What tells a page what it's 'system buttons' are supposed to be?
Or is my solution perfectly acceptable?
Thanks for your time,
P.

Hi Patrik,
Option to print a page is generally available with an overview page for any transaction.
In case you want to have this available for any other page then coding would be required.
I would say that your solution is correct.
