"The game is played on a receipt printer, a common device you can see at every convenient store. It prints those papers you usually find crumbled up in your pockets, just to throw them away. It is a thermal printer using heat to darken the paper.
This eliminates any slowdowns in printing lots of black. A roll can be ordered online and costs around 80 cents. 50 meters is the maximum distance you are theoretically able to race in one run, before running out of paper. So ecologically it's pretty much a disaster, just like any real car."
Back to basics :).
