Nobody likes clutter. In fact, the whole reason you moved to a wireless network in the first place was to get rid of that "magical mess" of cables and routers messing up your Feng Shui. Though the blinkenlights are cool, we'll keep those.
Not content to just leave a wireless router plugged into his old LaserJet, a guy named computerguru365 hacked the two devices together, creating his own network-ready wireless printer for far less than what an integrated unit would cost.
You'll need a printer, a cheap router running DD-WRT, a network adapter, soldering equipment and one of those clear plastic space-holder donut things that comes at the bottom of a spindle of CDs. Be warned: this project is hands-on and intensive. Not for the faint of heart.
