I found this written in Ruby several years ago. My two favorites were, "INSERT COIN" and "ADD WATER". Of course, this is only really effective when large groups use the same printer. It was mentioned somewhere as an IT prank for April Fools day.

  Sigh, it's "OUT OF WATER", not "ADD WATER". Only very new printers tell you how to resolve the problem ("Add Letter paper to tray 1"); old printers just tell you what the problem is. ("PC LOAD LETTER? What the fuck does that mean?") And for the OP, it's "INSERT COIN" not "INSERT QUARTER".

And I've seen one written in Perl that does the current weather. EDIT: http://miscellany.kovaya.com/2007/10/get-weather-on-your-hp-4200.html http://miscellany.kovaya.com/2007/10/get-weather-on-your-hp-...

This prank was also on TDWTF and I think my favourite message was "OUT OF CHEESE!"
