The "FKEY #4" command for printing dumps of the Macintosh screen is in the
process of being abandoned in all Print drivers for the Mac.  There are
several reasons for this, which I can elaborate on if anyone is interested,
but for starters it just plain doesn't work under some conditions not the
least of which is:
  * low memory (applications assume 10k is plenty for any printer)
  * multi-finder (how do you print dynamically changing screens? 2 screens?)
  * self portraits (how do you prevent FKEY #4 nesting?)
Though these may be considered soluble at some level, it is not considered
worth it since low-level print driver calls are being phased out.

The recommended way of printing screen dumps is to execute an FKEY #3 
(which saves the screen to a file) then printing the file like any other
bitmap file.  This is not only cleaner, its easier and is just as fast as
the FKEY #4.
