Hola:

I have looked around, but I believe older entries of your calendar may be deleted from your device.  If you want to print entries from your Blackberry calendar, my suggestion would be to do it through Google's calendar.  You would need to set up a GMail email account, which is free.  Then you would have access to a calendar which you could sync with your Blackberry.  Then, from the Google calendar, you could print a copy of your calendar.  I hope this helps.
