Many people would probably say the hard copy is a dead medium, but sometimes you just need to see the bigger picture on a full size plot.

I’m loving the innovation we’re seeing come out of crowd funded projects. This robot printer runs around the page laying down ink. As long as you have a flat surface large enough you can print to any paper size you need. Site teams could print off an A0 sheet in the lunch shed then put the printer away again in a drawer.
