Oh, and you can apparently use the same trick for Desktop Printing of documents, but I was never all that impressed by Desktop Printing anyways.
[Editor's note: This works as described! While it's a handy trick, if I have to drag a Finder window to be printed, I'll proably continue to drag things to SearchWare Solutions' PrintWindow (donationware), which offers additional options such as subfolder expansion and inclusion of icons.]
