Outlook doesn't have a way to print the reminders, but you can create a custom view and print it. Tasks uses the Reminder time field, Flagged messages use the Due by field. The calendar uses the Remind Beforehand field. The only problem is you see the reminder as minutes before, as in 15 or 45, not a specific time of day, like 9:15 AM.
If you want to see the reminder time using a date and time format ("Wed 12/1/2007 2:45 PM") you can create a custom field and enter a formula that converts the minutes before to a date.
The formula you need is
DateAdd("n",-[Remind Beforehand],[Start])
For best results, I recommend you create a custom view.




Notes:
Recurring appointments will show the reminder as of the starting date, not the next (or any future) recurrences.

As with anything recurring, this only works as expected for the first occurrence, but it works as expected for individual appointments. Oh, and it won't show the new reminder time on snoozed reminders.
Tip: the three line AutoPreview setting and in-cell editing is under Other Settings, if you want to disable either option.
