I have a plotter printing 1189mm bond paper.
When I print A3 format multiple sheets the plotter will take the height of the drawing paper format (A3 =297x420mm) and make a strip 297x1189mm for each sheet I print.
This leaves me with a strip 297x796mm of waste paper for each sheet. This waste could easily be used to print a second A3 drawing.
Arrayed printing as I have called it could also be used for diversified paper size printing. A1+A2+A2, A1+A2+A3+A3 and so on
In AutoCAD we used to put to drawings side by side and "print as one" to utilize the paper better.
This is a chance for Autodesk to reduce its indirect carbon footprint, grab it!
