I'm not at a Mac right now, so I can't give you a tested solution, but
here's a general idea:

Put an (in)visible field in the background, called "date".

Put a few lines in your background script that are activated whenever
you get a closeField, like this:

on closeField
  put the date into field "date"
end closeField

Theoretically, this will set the contents of the date field to the
current date whenever the card has been changed (I seem to recall a
problem if you go to another card without formally "closing" the field
(pressing tab).  I *could* be wrong).

  You'll also need a field somewhere that holds the date you last ran
your print script.  I'm going to wave my hands on the structure of the
print script (I haven't done much printing), and just say that you
search the stack for cards containing a date higher than the "last
printed" date, and print them.  When you're done, reset the "last
printed" date to the current date.  If you make changes frequently,
you may want time, too.

  Also, the default date format probably won't work (unless HC can
recognize it as a date), since 12/11/66 is greater than 11/10/88.

  If you need any further help, send e-mail and I'll send you a stack
that does this (which means I'll write one, just to prove I'm right :-))
