LEGO Printer
The beauty of Lego Technics and Lego NXT is that these can be paired with parts from other mechanical or electronic equipment. There are build instructions for using Lego NXT to build your own DIY printer, and with patience, you can do it in a reasonable amount of time. There are different models of the Lego plotter/printer, and it is all up to the creator which one he wants to make, and in what size.
