Printerface is something I cooked up to allow me printing to my 3d printers (reprap's) with the browser. This allows you to control your 3D printer over the internet using your laptop, ipad, iphone, Android phone or any browser capable device. It was made for the inexpensive Raspberry Pi (http://www.raspberrypi.org/) but it has also been reported to work with things like MK802 (https://www.miniand.com/products/MK802%20Android%20Mini%20PC ).
The cool thing about it is that with the raspberry or or mk802 like devices is that it prints smoother than using a laptop running a bunch of other services not needed for printing and it draws much less power. These mini pc's only consume 5-10watts instead of a laptop that uses +-80 watts...
Little video explaining the usage is on youtube: http://youtu.be/tsMdusrO6bk

git clone git://github.com/w-A-L-L-e/printerface.git
#forever keeps our printerface running even if it crashes, and creates a logfile while we're at it...
sudo npm install -g forever@0.9.2
#now actually fire it up, put this line in /etc/rc.local to have it on boot
cd /home/pi/printerface && forever start printerface.js
#I've also added another script that posts my ip in /etc/rc.local to my webserver. That way I can access it from the outside world too ;)
