A fellow who goes by the name "squirrelfantasy" (we're not going to ask) has put together a working printer that uses felt-tip pens instead of ink cartridges. The most impressive part, though, is that he built it entirely out of LEGOs.
Adorned with LEGO men and, really, only as pretty as it has to be to get the job done, the LEGO printer doesn't look like it's the fastest, though it does create a pretty unique printout. The pen slides back and forth, building images and text one line at a time. It'd probably have trouble with the finer details, though maybe it could just use a finer pen.
Check it out in the video above.
