If the reminders are from your "calendar" folder, go to Advanced Find
(Tools...Find...Advanced Find <or> Ctrl+Shft+F). Select the "Advanced" tab.
Select the "Field" button, go down to "All Appointment Fields" and select
"Reminder" and "equals to Yes". This will result in a list of all
appointments that have reminders associated with them. You can then print
the list by clicking on File...Print.
