The CREATEDATE could be later than the PRINTDATE if, for example, you
a. create a new blank document, say with a PRINT field
b. print it
c. save it as a template (.dot)
d. close it
e. create a new document based on that template. The PRintdate has not
changed, and the create date will be later.
There are probably several other scenarios where you might get the same
thing, e.g. someone's system clock was wrong when they created or printed
the document.
