Hi Pilou, well as far as I know all the new styles of plotters work like giant inkjet printers, like the one that you showed in your message here: http://moi3d.com/forum/index.php?webtag=MOI&msg=1949.4 - is like that, it will use an ink jet mechanism and not pens to draw that large forest poster that you showed.

If you want to drive one of the real pen plotters, I think those require some special software that knows how to emit the instructions for moving the pens around, if I remember right those styles of printers do not get set up with a general Windows printer driver.

As far as I know that kind of a pen plotting system is quite old now and you may need to use some older software to drive it, I would recommend looking for an older version of AutoCAD for that possibly.
