Train your HP printer to harass your office enemies

All you need is this little perl program, developed by this guy. Get it going and you can have your local document demon start back-talking in no time, if only to demand quarters that the staff will have no visible method of inserting. And that's just for starters:

"I wrote a more elaborate version that takes advantage of the HP 4200's larger, four-line display. It sends the current weather conditions which I grab from NOAA using the perl Geo::METAR module. It updates every 10 minutes. Amazingly, while many people noticed the report on the printer display, no one questioned it!"

Ladies and gentlemen, start your hacking.
