How to print a Spool File?

Hi guys, Actually i’m stuck with printing the spool file.

I’ve done a simple Screen(DSPF), Printer File(PRTF).
For example: i have a screen then press any function key, eg:F9. When pressing the F9 it will call my program that generate a report which is store in Spool File(WRKSPLF).

I’m just wondering when pressing F9, i just wanted it will print the spool file from the printer. What should i do? Is there any Program need to call (CLLE) in order to do the settings? Do you have the example code?

Thanks for helping.
