HELP!!! I dunno how to print the date using the Canon S45

[mikpsnco]

Help please... I want to print the date of the picture taken on the photo. I plan to have the picture developed at a Photo store. My friend has a sony and he has the option to have the date appear even when just viewing it on the computer. How do I do that? Is the Canon S45 capable of doing so? Or is there a program I can use to produce this?
