Amazing Lego Printer Prints Direct from a Computer
This is one amazing printer built from Lego parts and some electronic wizardry. Never mind that the ink cartridge is just a felt-tip marker pen. The fact that something like this actually works simply blows our minds.
The coolest part has to be that the Lego printer was connected to a computer and printed stuff direct from the screen from its own custom driver. The end result is quite unbelievable considering that only a single marker pen was used and not some fancy top-class inkjet cartridge system.
